There's a few things that might cause a limit switch fault on any 3d CNC controller to troubleshoot: I just learned this!!) Shapeoko 3 Z-axis The Shapeoko 3 uses a belt-driven Z-axis, requiring an endless loop 6mm wide GT2 belt. The Z-axis will then back off slightly before re-engaging the switch and then backing off for a final time and setting the Z-axis to machine origin ― this will display as Z=−5 (the 5mm away from the machine origin that the machine backs off after homing) until an origin is set If it is able to move down okay, but will not move up reliably, then the acceleration or movement may be too fast or high. I did the XXL upgrade last week and installed the limit/homing switches (after having to adapt it to my Ver1 end plates). Each limit switch is attached to a twisted-wire pair of black and yellow wires. I took it off, and the “button” is broken off inside the little cover. Having problem with limit switch hit.

Now, when I attempt to home, the z axis travels down instead of up toward the limit switch, ... about 3 weeks ago I ordered a shapeoko 3, … Here's an example of a proximity switch for the Z-axis: They can be used as an (almost) drop-in replacement for the original switches, the only difference is that (depending on their technology) they may need an additional lead for power supply, connected to one power pin of the controller board (typically, the 5V pin on the Arduino ISP header, see Anatomy of a Shapeoko for details). a) GRBL AIO (Arduino + Drivers + Filters + more So I went back to Teh Google and found the real pinout for the GRBLShield and sure enough, the limit switches go on pins 9, 10 and 11. Where can I order new switches (without the wiring) so I can keep a few on hand if this happens again? To protect his machine from human error, [Zorlack] decided to make limit switch brackets for his Shapeoko. The Z axis actually turned out kind of slick – I ended up only using one switch. Which means that the minimal movement that the Shapeoko can theoretically do in any axis is 1/40th of a mm, that's 0.025mm or 0.001''. Hoping perhaps their quality is somehow different from the ones I got on Amazon. It worked great! When one switch gets tripped it will pull the other low. The drag chain is at an angle towards the front of the machine. One for the X axis, one for the Y axis, and one for the Z axis. The ones that came with my machine seem to be Omron D2QW-C003H. Here's more or less how I have my limit switches wired. There is 1 home switch per axis of your machine (3 total). Add to that they are $6+ a pop, plus shipping. I did the XXL upgrade last week and installed the limit/homing switches (after having to adapt it to my Ver1 end plates). Once I figured that out, it worked as expected! The community maintains a list of parts and other notes on the machine: http://www.shapeoko.com/wiki/index.php/Home/Limit_Switches#Shapeoko_3, http://www.digikey.com/product-detail/en/omron-electronics-inc-emc-div/D2QW-C003H/SW1221-ND/2698560, This may be a little late, but my Z axis switch stopped working on the second day of using my SO3 XXL.
