So in this post – Limit Switches for the ShapeOko – I installed some optical switches as limit switches. Second, if the homing cycle doesn't disengage the limit switch when trying to pull off them. It is about 3/16” tall. 5. Try increasing pull-off setting or check wiring. Step 7: Limit Switch *****UPDATE 2-20-2019***** This limit switch block is only for older style mounts. Try increasing max travel, decreasing pull-off distance, or check wiring." The only time a limit switch should be hit is during a homing cycle, at any other time it will stop the system. The Carbide 3d support team sent me a switch very quickly-I received it today, installed it, and everything works as normal now! All of the rest, which is the entire Shapeoko kit, along with the parts to upgrade everything to a Shapeoko 2 (stiffer z axis gantry, new belts all around) plus other enhancement parts I never got around to using - including those needed to make a control box with detachable cables, limit switches, emergency stop button, etc. I'm making a PCB for my Shapeoko desktop CNC machine in order to isolate the Arduino Uno from noise on the limit switch wires and pushbutton wires. The Shapeoko is a great machine out of the box, and there is really no need to modify it to get good results. Tonight, while initializating my machine for the first time in a week, it went to the back right corner like it normally would before making all kinds of cringeworthy noises. Hello, my new Shapeoko XL ran the paper test OK. They were working pretty well until I did a job boring 66 largish holes in some MDF. See GRBL detailed documentation on what these do. I’m still a bit gunshy about something happening again, but they also mentioned to resend the machine configuration since I set up a new laptop (https://docs.carbide3d.com/support/carbideupdater/#carbide-motion-v4). Ok, I’m looking for a little bit of help, please! If the machine is jogged outside of the limit switches, it completely defeats the purpose of soft limits. Powered by Discourse, best viewed with JavaScript enabled, https://docs.carbide3d.com/support/carbideupdater/#carbide-motion-v4. The Shapeoko 3 limit switch kit from Carbide 3D provides an easy and reliable way to add limit switches (home switches) to your current setup. Check for any contact to the frame. I will ohm out the switch to see if it failed. With the way the table is setup (currently) the tool will bury itself through the table before the limit switch is even triggered so, _for now_, it will work. Cookies help us deliver our Services. The Shapeoko uses our Carbide Compact Router or you can provide your own DeWalt DWP-611 or Makita RT0701C as a spindle. First of all, I have an early XL with a version 2.3 control panel, the HDZ, touch probe, and bit setter. Still, once you are reasonably comfortable with the machine, and how to set optimal CAD/CAM parameters, chances are you may be tempted to optimize the machine itself. The machine never touched the z limit is what has me confused. A few thoughts, with the machine powered off, manually rotate the ball screws to move the machine away from the limit switches. So in this post – Limit Switches for the ShapeOko – I installed some optical switches as limit switches. After restarting my computer, I was greeted with this wonderful error: ... Shapeoko 2 – X/Y/Z Limit Switch Mounting Bracket Fabrication; Battlefield 4 – Adjustable Vehicle Respawn Countdown Timer; Recent Comments. Grounding the pin tells GRBL the limit switch is tripped. The main reason for doing this is electrical noise from the stepper motors and from the router motor can cause the limit switch inputs to trigger. NO tends to be more prone to interference on the tinyg, not sure if the same is true for the Carbide3d. I did send a request to support, but I figured I would put this out there to the forum to see if there is anything I can look into in case it takes time to hear back from support. This page was last modified on 11 July 2014, at 20:56. Im not surprised if support has been in touch with you already and solved this issue! The Shapeoko XXL ships with three (3x) limit switches. I got a message back saying there was a serial error, so I turned off and disconnected my Xxl. The limit switches seemed to be working great, and I was loving being able to home the machine and not have to re-zero my work all the time. Shapeoko accepts standard gcode so you can use almost any CAM software. Need assistance. Learn and Share with us! After about 5 seconds I was finally able to shut off the machine at the power switch. (These are pins 9,10 & 12 in Arduino Talk) When you hit a limit switch, the limit switch connects/shorts this pin to ground causing the voltage on this pin to rapidly drop from High State (5V) to Low State (0V/GND). It seems to be the switch itself and not the board. I had a limit switch issue that turned out to be largely due to outdated assembly instructions on the Carbide 3D website. What might I be doing wrong? Then set the GRBL "soft limit" settings appropriately, e.g., $130=415.000 (x max travel, mm) $131=430.000 (y max travel, mm) 840mm works well for a Shapeoko XXL. Then it gave me a Z limit switch error. Homing fail occurs in two scenarios. Limit -- Illuminates when a stop switch is active; Stepper Motor Connection; Axis driver -- DRV8811; Microstepping Control Switches; Heatsinks -- One each on the driver IC and a collective aluminum slug on the backside; Current control potentiometer; Operation. I went through some troubleshooting steps on the Carbide website and have not been able to make any progress. Symptoms: The console window will show the command being sent and a confirmation of "ok".However, the active state goes to "Queue" and never returns to "Idle." Grbl (pronounced gerbil) \ˈjər-bəl\ is a CNC controller software that runs on an Arduino (or similar) microcontroller.. From the Grbl Github page: Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. ALARM:9 indicates "Homing fail. This usually results in a grinding noise as the hard stop engages while trying to find the home switch. Thanks for the help from everyone in support (Will and Adam) as well as Kenneth in this thread! Thanks again for the help, you’ll allow me to sleep much better-these types of things keep me up all night if I don’t have at least some idea of what’s going on before I get to bed, ha! The most affordable and capable bench top CNC router kit available. All three work well on Shapeoko. I bought a shapeoko and I installed limit switches as described in the Wiki. I even got some work done. The switches have a repeatability rating of .3mm (.012″) which is pretty good. Christmas Tea light - CNC build - Carbide 3D shapeoko 3 XXL - Duration: 8:04. Winston Moy 36,048 views. New comments cannot be posted and votes cannot be cast. and ox, there is allot of interference in the device due to all the equipment and power sources in the mix. No, really, check out Winston Moy's videos if you need convincing. Not long after, it’s my Y. One for the X axis, one for the Y axis, and one for the Z axis. I wasn’t sure what happened, then I saw that I had an error that said GRBL failed, homing error, pull off didn’t clear. The instructions will help you install the limit switch kit sold through the Carbide 3D store. Second, if the homing cycle doesn't disengage the limit switch when trying to pull off them. Starting at $1320. I followed the wires down and all the sheathing is there. I am pretty sure it is the switch but thank you VERY much. Instead of holding down PROG key, simply hold the Z axis limit switch while programming. After messing around for a bit I unplugged the switch 1 by 1, and sure enough when i unplugged the z axis switch the error went away and could run homing at least (although I had to kill it asap to keep it from bouncing off of the z axis.). If not, the RF from the servo motor wiring will induce a current in the limit switch wires -tripping the circuit. Very interesting, let me know what you find out. To protect his machine from human error, [Zorlack] decided to make limit switch brackets for his Shapeoko. It goes between the fan and the input control cable. This info will be filed away for future troubleshooting. Sounds like your Z Switch is triggered all the time. The take advantage of the homing switches on your Shapeoko CNC router, homing will need to be enabled in the machine control software Carbide Motion. Sounds like you better get a new one, but please do post a picture of this when you have time. would I contact customer support on carbide 3d’s actual website? edit Tested and was getting continuity from the switch. Thanks for the help, I think this helped me make some progress before going to bed for the night. Do I need to do something to reset up the machine with the new laptop? After looking at the limit switch, the little pin had been sheared off and the switch was crooked. I have exactly the same issue installing HDX. If you have a multimeter, this also comes in handy for testing. The Shapeoko is made in the US and comes with a 12 month warranty. While I'm not familiar with the carbide3d (or the Shapeoko3), I do have a 1M x 1M Shapeoko 2 with a Tinyg. Ok you should be able to see one button above called "PROG" and on the other end of the board there is another called "RESET" see picture below. I’ll report back once the parts are in to make sure it worked. *edit (NO, not NC for #4), Reversed NO for NC on #3 (see how easy it is to get those mixed up!). Available in 3 sizes. The Shapeoko 2 from Inventables was my second milling machine (after the Roland iModela, which I blogged about before). Ellen, I just completed putting my Shapeoko 3XXL together and I have downloaded Carbide Motion onto my laptop. Make sure the controller board configuration matches the connection to the switch. Hard Limit Error, A limit switch was triggered, this always results in the end of your job. New replies are no longer allowed. Record the machine coordinates at the end of the travel. As shown in the documentation. After looking at the limit switch, the little pin had been sheared off and the switch was crooked, a bit up in the error. You can build it in about 2 hours. 4DThinker Vectric Wizard Posts: 1403 Joined: Sun Sep 23, 2012 12:14 pm Model of CNC Machine: CNC Shark Pro, Probotix Meteor 25" x 50" All signs pointing to a switch? Thanks again for the help, guys! I don't intend this post to be an extended comparison of the iModela and the Shapeoko 2- they're different machines aimed at different markets. There's a few things that might cause a limit switch fault on any 3d CNC controller to troubleshoot: Are the limit switch wires shielded? There's a few things that might cause a limit switch fault … It most definitely is bad. I cannot see anything light up when I push any of the switches. Error(10) GRBL Error: Homing Failed, couldn’t find limit switch. I tried to look somewhere beneath them and see nothing. Could this be due to a faulty switch? UPDATE: (You don't have to do this if you have limit switch on the Z axis. Carbide Answers 874 views. I double checked and made sure the switch is plugged into the appropriately labeled wiring, even unplugged and replugged everything. The only time a limit switch should be hit is during a homing cycle, at any other time it will stop the system. I will say that I got a new laptop since the last job I ran, and the new version of carbide motion it picked up was 4.28, whereas my old had 4.17. I would say “measure twice, then recheck everything one additional time, and then cut, while keeping your hand on the power switch”. However, I agree with your assessment. A CNC can have one or two limit switches per axis. I just learned this!!) The good folks at Carbide support, who solved the problem for me, say that updated assembly instructions are imminent. Must be tolerance stack up on the HDZ because mine engages just fine…the only issue with mine must have been that it failed before the machine homed. While I'm not familiar with the carbide3d (or the Shapeoko3), I do have a 1M x 1M Shapeoko 2 with a Tinyg. I’m not sure when the new one will make it here, but I’ll test it and report out as soon as I get it. r/shapeoko: Do you use a ShapeOko CNC machine? However whenever I tried to run my first project it would start at a random set points. I am using the Lightburn software to run the laser as that is what JTech recommends but after I follow the set up instructions, Lightburn does not find my laser. So I'll limit my comparison to the two points below: Whereas the… Unfortunately, I do not have the factor GRBL presets for the 3018 Pro. I followed all the instructions and set it up as so. 5:25. Does the carbide 3d like them wired normally open (NO) or Normally Closed (NC)? [35] Another possibility is a poor connection between the gShield and the Arduino --- if all other connections are good, then try unplugging/replugging. Hard Limit Error, A limit switch was triggered, this always results in the end of your job. All the instructional videos and blogs automatically assume Lightburn will find your laser. The Shapeoko is made in the US and comes with a 12 month warranty. Jog command has been ignored. If the limit switches are active, this will also be displayed in Carbide Motion on one of the tabs, but i cant remember which one. Learn and Share with us! If for some reason support is not supplying a switch, they can be purchased here and many other places. No, install Carbide Motion and Carbide Create and thats it. Homing switches are now standard on all Shapeokos. That’s interesting, I wonder what is different. When i enable the limit switch by issuing the $16=1 command and I try moving any of the axes, I get the HARDLIMIT alarm, and i have to reset. While I'm not familiar with the carbide3d (or the Shapeoko3), I do have a 1M x 1M Shapeoko 2 with a Tinyg. Could not find limit switch within search distances. This distance is about 1.5 times the max travel of the axis. Each of the limit switches reduces axis travel by less than 3mm. Could not find limit switch within search distances. I also had to put a block of plastic w/ two way tape on top of the z axis carriage because the homing/limit switch was not being engaged. It's easier than you think, and super useful. They were working pretty well until I did a job boring 66 largish holes in some MDF. Ships Free in the US. @ThomasDalgas: ALARM:9 is totally different from error:9. With all of the wires connected and routed back to the controller, you can safely remove the controller cover again. One possible issue will be if I get false limit switch trips due to swarf getting into the switches. Build info or startup line exceeded EEPROM line length limit. After some searches here, I tried to check my switched on the control panel by pushing each one and checking to see if they lit up. I have checked wiring, and tested the limit switches to a point. For instance, if I zero Z (for G54) at -3" from the Home switch.. Then I should be able to run G-code that moves the machine up to +3" (ish) as that is the actual limit.. The switch is normally open. First it was my Z limit, which Carbide was nice enough to send a replacement for. Carbide sent a new switch. $130, $131, and $132 parameters respectively control X, Y and Z maximum travel : (carefully) jog to the limit of each axis, leaving a small margin you are confortable with, write the current axis value in millimeters, drop the minus sign, and set it in the corresponding parameter (e.g. First, when Grbl doesn't find the limit switch within a search distance. type in $130= in the GRBL console). i also have the same problem , fitted the HDZ UPPGRADE then got exact same error, im convinced the z switch got broke while fitting the hdz but need to get replacement, im in uk , any idea who would I contact to find out? The Shapeoko is partially assembled. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. Shapeoko comes with an industrial-grade motion controller running GRBL firmware, homing switches, and 4 NEMA 23 stepper motors. Grounding the pin tells GRBL the limit switch is tripped. Basic Shapeoko Limit Switch Troubleshooting - Duration: 2:21. edit Contacted carbide3d and they quickly responded, and have a new switch on the way! Let us know how it turns out or if you need some help. The above code is the portion I changed for the Y-axis. Do I need to do something to reset up the machine with the new laptop? 4DThinker Vectric Wizard Posts: 1403 Joined: Sun Sep 23, 2012 12:14 pm Model of CNC Machine: CNC Shark Pro, Probotix Meteor 25" x 50" Do you use a ShapeOko CNC machine? There's a few things that might cause a limit switch fault on any 3d CNC controller to troubleshoot: It sounds like a limit switch is active. We’ll see. Homing fail occurs in two scenarios. Carbide Create CAD/CAM Software. Depending on the version of Carbide Motion you are using, the instructions vary. Ok you should be able to see one button above called "PROG" and on the other end of … Try increasing max travel, decreasing pull-off distance, or … I had just the X limit switch plugged in, when I pressed it the corresponding X LED light lit up blue. At the heart of each axis driver is a DRV8811 IC by Texas Instruments. Posted on September 21, 2013 by Timothy Foreman. , if not they will most likely send you a new switch if that turns out to be the problem. @ThomasDalgas: ALARM:9 is totally different from error:9. I repositioned it and tightened it down to try again, and I got the error again and the z axis just plunged down an inch or so without doing anything else. The problem with that one is I am having the hardest time finding a place to mount it. This refers to the limit switch pins which by default are set to high using the Arduino's internal pull up resistors. Otherwise, I have something else going on that popped up out of nowhere. The problem with that one is I am having the hardest time finding a place to mount it. Solution: loosen the mounting screws (M5x35mm BHCS) and slightly rotate the mounting plate to better contact the edge plate. Looks like you're using new Reddit on an old browser. Tested the board by jumping the contacts and it does think the limit switch is hit when I do, so the board is good. The electronics work on 110V or 220v. 3.Jog the machine to the maximum desired position within the limit switches. Review the items below to help you identify what could be causing your limit switches not to trigger. With the way the table is setup (currently) the tool will bury itself through the table before the limit switch is even triggered so, _for now_, it will work. Thanks again for the help, and here is the image of the switch. I did swap the y and z switches at the control panel and it did at least send the z axis back up to the top before crashing into the switch. Limit Switch Holder v4.stl (71 KB) View 3D Render Download Note: if you want to re-download a file, please do so from your Purchases page or the product page. All three work well on Shapeoko. The purpose of the limit switch is to send a signal that will stop the axis from trying to move past the end of its travel range. I still can’t find anything on the control panel lighting up when I push the switches, but I did open the log and was able to see some lines that appeared to point toward the x and y axes when I pushed those switches, and nothing seemed to happen with the z. I’m hoping that means that switch failed and I just need to see if I can get a new one form carbide. ***** I shouldn't be blocked by +.5" as being above the soft limit as the soft limit should only be in consideration from the perspective of the table, not the G-Code coordinate. This is … Try increasing max travel, decreasing pull-off distance, or check wiring." Error: GRBL ERROR: homing failed, couldn’t find limit switch. Electronic limits 2.5mm Electromechanic switches 4mm e.g. Seems like too much of a coincidence. Note: This video is super obsolete. 15: Travel exceeded: Jog target exceeds machine travel. Could not find limit switch within search distances. Installing the Limit Switches. They are 3D printed, accept standard limit switches … This distance is about 1.5 times the max travel of the axis. Machine won't start. My Shapeoko 3 was fairly easy to assemble, even though I'd never built a CNC mill before. r/shapeoko: Do you use a ShapeOko CNC machine?

Listed below are several common problems found during home switch installation and initial setup. Installing a Homing and Limit Switch Kit - Shapeoko Project #48 - Duration: 5:25. See the Shapeoko . I removed the switch and checked it with an Ohm meter and it is defective. Press question mark to learn the rest of the keyboard shortcuts. Thanks again for your help. 16: Invalid jog command: Jog command has no '=' or contains prohibited g-code. To protect his machine from human error, [Zorlack] decided to make limit switch brackets for his Shapeoko. Shapeoko 3 XL CNC Router, Unbox/Assembly - Duration: 7:20. Homing fail. The Shapeoko 3. 2:21. 17: Setting disabled: Laser mode requires PWM output. It sounds like maybe it’s more of a “sure” thing to do vs a “have” to do, but I’ll go ahead and do that as well once I get the new switch installed. Limit switches are essentially homing switches doubled up and in addition to setting the origin are used to prevent the motors from hitting the end of each axis which can cause serious alignment problems, potentially serious damage to your Shapeoko, destroy a bit, or ruin a work piece. I have reinstalled Carbide motion a few times, with no luck. I finished adding all the limit switches to the shapeoko except for the z-. I suppose I need to hope that the last switch failed before it was touched by the HDZ, hence allowing the crash. The switch mounting plate is tilted in the wrong direction, causing the gantry plate to contact the hard limit. Open loop means that there is no feedback to the controller. Thanks for any help you guys can give! This topic was automatically closed 30 days after the last reply. This refers to the limit switch pins which by default are set to high using the Arduino's internal pull up resistors. The newest magnetic mounts do not need the limit switch block. The DIP switches on the Carbide Motion Control Board add another possible poor connection --- toggle the switch on a misbehaving axis several times to improve the connection. The Limit Switch and Probe settings depend on how you wire these up as to what polarity is required. You can just run it next to the power cable for the shapeoko 3. Pull off travel failed to clear limit switch. The electronics work on 110V or 220v. The picture is to show that the limit switch is getting touched by the z-axis plate. So make sure you have your max travel settings roughly correct. You can remove the switch from the troubleshooting and test the board with a set of jumper wires across the switch input terminals (you're the switch now!) The Shapeoko is quite affordable and worth every penny, yet with all required accessories the entry cost is somewhere around in the 1500-2000 euros range. Faulty Switch: Test continuity across the contacts while throwing the switch; NC should show continuity when the limit switch is untouched, then show open when the switch is down. This is a GREAT Idea ... and did not even cross my mind to try. That made a lot of dust – more than my vacuum could keep up with – and the dust got into the limit … Invert Bits Grbl0.9 20: Unsupported command ShapeOko Limit Switches Update. For the opposite behavior use the setting $5=1 which tells the system that a high is the limit switch trigger. The next pair of settings, Junction Deviation and Arc Tolerance rarely require change. NO is the opposite, with continuity only with the switch is thrown or made. If I manually press the limit switch twice while it is trying to home it then homes the other two axes perfectly. Yes, if you haven’t already, contact support@carbide3d.com and we’ll work out how to get a replacement switch to you. I just learned this!!) This requires soldering as it does not come with connected wires and connector as it does fromC3d. Wether you are using a reprap style printer or a cnc router or other cnc tool like the open source shapeoko(2) .
