Hello, I’ve been trying to get the touch probe to work for a while, but I can’t. I tried the different wiring mode presented here: https://docs.carbide3d.com/assembly/touch-probe/#version-24de. The card used is version 2.4. When I connect the electrode to the ground (using one of the controller fixing screws) and I make the contact, the controller shut down (as soon as I stop the contact it turns back on). I can’t get the red LED when contacting. I have updated the firmware (GRBL V1.1) and I use create motion 5. Any idea to help me?
Sounds like a short.
Can you get a photo of your connections?
Just my $0.02:
any chance that when you grounded the probe in that lower right corner you showed, it contacted with the pin header nearby (circled in the pic below)?
Unless I am mistaken, one of those pins is wired to 24V, so an unintended short to GND there would…be bad.
I’m sure, there is no contact with this pin header.
I disassembled the probe and i saw that the red wire was pinched under the screw ! It was the reason of the short !
Now the probe works !
Thanks for your help.
Good detective work Ben, and I’m sorry for the mistake on our end. If you’d like us to replace the probe, just shoot us an email.
