4. edit Tested and was getting continuity from the switch. *Note: Make sure to stay inside the physical limit switches. I got a message back saying there was a serial error, so I turned off and disconnected my Xxl. 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? The instructions will help you install the limit switch kit sold through the Carbide 3D store. All three work well on Shapeoko. First of all, I have an early XL with a version 2.3 control panel, the HDZ, touch probe, and bit setter. New comments cannot be posted and votes cannot be cast. I am pretty sure it is the switch but thank you VERY much. I would say “measure twice, then recheck everything one additional time, and then cut, while keeping your hand on the power switch”. The switch is normally open. Homing fail occurs in two scenarios. This is … 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 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. However, I agree with your assessment. The switch mounting plate is tilted in the wrong direction, causing the gantry plate to contact the hard limit. 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. Ships Free in the US. Probably good enough for most of what I do, though I might run some tests later to see what actually happens. 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. So make sure you have your max travel settings roughly correct. Im not surprised if support has been in touch with you already and solved this issue! Check for any contact to the frame.

I have went off of Sam Wong's Replicape configuration and edited a little to include the gantry component of the Comet. NO is the opposite, with continuity only with the switch is thrown or made. See GRBL detailed documentation on what these do. They were working pretty well until I did a job boring 66 largish holes in some MDF. At the heart of each axis driver is a DRV8811 IC by Texas Instruments. Thanks again for the help, and here is the image of the switch. I even got some work done. 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.

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. I did swap it. 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.
