All signs pointing to a switch? I have went off of Sam Wong's Replicape configuration and edited a little to include the gantry component of the Comet. The Shapeoko is made in the US and comes with a 12 month warranty. 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.). Note: This video is super obsolete. The switch mounting plate is tilted in the wrong direction, causing the gantry plate to contact the hard limit. Looks like you're using new Reddit on an old browser. 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. This is … 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. ... started and promptly stopped the job, and all hell broke loose. 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..

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! Let us know how it turns out or if you need some help. I followed all the instructions and set it up as so. Solution: loosen the mounting screws (M5x35mm BHCS) and slightly rotate the mounting plate to better contact the edge plate. The machine never touched the z limit is what has me confused. I finished adding all the limit switches to the shapeoko except for the z-. The Shapeoko XXL ships with three (3x) limit switches. Support was all over it like you mentioned and is sending me a new switch, so hopefully this guy will be up and running again soon. 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. Starting at $1320. Thanks for the help, I think this helped me make some progress before going to bed for the night. 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.

Carbide Create is our free design software that’s easy to learn and powerful enough to grow with you. First, when Grbl doesn't find the limit switch within a search distance. I cannot see anything light up when I push any of the switches. While I'm not familiar with the carbide3d (or the Shapeoko3), I do have a 1M x 1M Shapeoko 2 with a Tinyg. 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. 15: Travel exceeded: Jog target exceeds machine travel. I will ohm out the switch to see if it failed. 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. I did swap it. I had just the X limit switch plugged in, when I pressed it the corresponding X LED light lit up blue. I’m still a bit worried about installing the new and it happening again. Not long after, it’s my Y. Homing fail occurs in two scenarios. All wires have crimped terminals and headers, and are color coded for easy attachment. If the machine is jogged outside of the limit switches, it completely defeats the purpose of soft limits. 5:25. @ThomasDalgas: ALARM:9 is totally different from error:9. Sounds like your Z Switch is triggered all the time. 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" Ok you should be able to see one button above called "PROG" and on the other end of … To protect his machine from human error, [Zorlack] decided to make limit switch brackets for his Shapeoko. This refers to the limit switch pins which by default are set to high using the Arduino's internal pull up resistors. Also, homing is blocking and will not show any feedback until it completes. I just learned this!!) To protect his machine from human error, [Zorlack] decided to make limit switch brackets for his Shapeoko. I’ll report back once the parts are in to make sure it worked. This is getting overly frustrating because I cannot use my shiny new probe without GBRL 1.1, and I can’t use that without homing, which I can’t do without working switches. For the opposite behavior use the setting $5=1 which tells the system that a high is the limit switch trigger. Open loop means that there is no feedback to the controller. I continue to have issues with limit switches. This requires soldering as it does not come with connected wires and connector as it does fromC3d. UPDATE: (You don't have to do this if you have limit switch on the Z axis. Review the items below to help you identify what could be causing your limit switches not to trigger. 20: Unsupported command So make sure you have your max travel settings roughly correct. Invert Bits Grbl0.9 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. See GRBL detailed documentation on what these do. Grbl (pronounced gerbil) \ˈjər-bəl\ is a CNC controller software that runs on an Arduino (or similar) microcontroller..

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. However whenever I tried to run my first project it would start at a random set points. As shown in the documentation. Try increasing max travel, decreasing pull-off distance, or check wiring." Do you use a ShapeOko CNC machine? Ok, I’m looking for a little bit of help, please! Essentially, I wired the limit pin directly to the switch, and the switch to ground. No, install Carbide Motion and Carbide Create and thats it. ShapeOko Limit Switches Update. They were working pretty well until I did a job boring 66 largish holes in some MDF. auto cycle start ($14) has been turned off Note that turning off auto cycle start requires that one begin the machine manually by typing ~. I removed the switch and checked it with an Ohm meter and it is defective. Unfortunately, I do not have the factor GRBL presets for the 3018 Pro. I assumed it had something to do with the limit switches not being set and followed the message threads to remedy that situation in Carbide Motion Settings by changing the “Shapeoko Has Homing” to “true” / Table X to 850 / Table Y to 430. We’ll see. Please help Hi gang…connected my lap top for the first time… tried to home and the cycle failed. One possible issue will be if I get false limit switch trips due to swarf getting into the switches. 3.Jog the machine to the maximum desired position within the limit switches. Could not find limit switch within search distances. 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. 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. Just installed the carbide3d set on my Shapeoko3 xxl and getting limit switch error in carbide motion. Learn and Share with us! ***** (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). The Shapeoko uses our Carbide Compact Router or you can provide your own DeWalt DWP-611 or Makita RT0701C as a spindle. 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.

I bought a shapeoko and I installed limit switches as described in the Wiki. 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). You can build it in about 2 hours. 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. 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. The Shapeoko is partially assembled. Hard Limit Error, A limit switch was triggered, this always results in the end of your job. Do I need to do something to reset up the machine with the new laptop? $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. So I'll limit my comparison to the two points below: Whereas the… Error: GRBL ERROR: homing failed, couldn’t find limit switch. It is about 3/16” tall. 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. Homing fail. So in this post – Limit Switches for the ShapeOko – I installed some optical switches as limit switches. 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. What might I be doing wrong? Could this be due to a faulty switch? [35] Another possibility is a poor connection between the gShield and the Arduino --- if all other connections are good, then try unplugging/replugging. 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. After looking at the limit switch, the little pin had been sheared off and the switch was crooked, a bit up in the error. This is the bleeding edge. New replies are no longer allowed. Hard Limit Error, A limit switch was triggered, this always results in the end of your job. , if not they will most likely send you a new switch if that turns out to be the problem.

Very interesting, let me know what you find out. I am pretty sure it is the switch but thank you VERY much. Second, if the homing cycle doesn't disengage the limit switch when trying to pull off them. The most affordable and capable bench top CNC router kit available. Line not stored. All three work well on Shapeoko. A CNC can have one or two limit switches per axis. This refers to the limit switch pins which by default are set to high using the Arduino's internal pull up resistors. Try increasing max travel, decreasing pull-off distance, or check wiring." 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. Probably good enough for most of what I do, though I might run some tests later to see what actually happens. I finished adding all the limit switches to the shapeoko except for the z-. The picture is to show that the limit switch is getting touched by the z-axis plate. Sounds like you better get a new one, but please do post a picture of this when you have time. Then it gave me a Z limit switch error. The wire run is free of any kinks or moving parts. ALARM:9 indicates "Homing fail. I suppose I need to hope that the last switch failed before it was touched by the HDZ, hence allowing the crash. 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. With all of the wires connected and routed back to the controller, you can safely remove the controller cover again. 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. 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. I had a limit switch issue that turned out to be largely due to outdated assembly instructions on the Carbide 3D website. - Answered by a verified Tech Support Specialist We use cookies to give you the best possible experience on our website.

Electronic limits 2.5mm Electromechanic switches 4mm e.g. Content is available under Creative Commons Attribution Share Alike unless otherwise noted. On a NO setup any short to the frame will make the board think a switch is thrown. The only time a limit switch should be hit is during a homing cycle, at any other time it will stop the system. The switch is normally open. $27=4: 9: Homing fail: Homing fail. This distance is about 1.5 times the max travel of the axis. 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. Make sure the controller board configuration matches the connection to the switch. They are 3D printed, accept standard limit switches … Shapeoko comes with an industrial-grade motion controller running GRBL firmware, homing switches, and 4 NEMA 23 stepper motors. *edit (NO, not NC for #4), Reversed NO for NC on #3 (see how easy it is to get those mixed up!). Grounding the pin tells GRBL the limit switch is tripped. One for the X axis, one for the Y axis, and one for the Z axis. Otherwise, I have something else going on that popped up out of nowhere.
