Ender 5 - CR-Touch on Duet Mini 3 5+
-
I cannot for the life of me get the CR-Touch to work with my Duet Mini 3 5+ When the printer is turned on the probe does NOT self check but flashes red - Reset probe macro does reset the probe to a purple light.
Using deployprobe.g causes it to revert to red flashing
Once in a blue moon I am able to use the deploy and retract macros to move the probe but only for a few mins and then it goes back to flashing red.

Bltouch/crtouch will not work with common ground both grounds must be on separate pins. I tried a similar configuration last year and feel your frustration.

@Macgyver How did you resolve that did you have to use the gnd pin on a nearby IO for the other earth?
-
Yes correct, the black wire is not actually ground, the brown one is. The black wire (on factory bltouch units is actually a low digital. It's called ground but it's part of the pio.
I just got a new phone and do not have the pic, I will look for my old post and put a link to it here.

@MightyRaith my best guess is that you have a bad crimp connection in either the ground pin, the 5V pin or the control pin.
Which firmware version are you using on the Duet 3 Mini? There was a startup timing issue that affected some BLTouch devices attached to Duet Maestro boards, which was fixed in a recent firmware version (3.4 AFAIR). It might possibly affect Duet 3 Mini too although we had no reports of that.
