Bltouch Configuration Issue
-
@Phaedrux Yes it works fine on my other machine but it not a duet2 wifi it a marlin based system.

Ok, so go through this checklist with me
- probe works on another machine no problem?
- when powered on the pin deploys and retracts in self test and then stays retracted with a solid red light?
- M401 and M402 work to deploy and retract without issue?
- G30 deploys the pin and moves the Z axis properly?
- hitting the pin while it's doing a G30 causes it to error?
- does it stop the z axis movement?
-
- Yes
- Yes
- Yes
- Yes
5.Yes a gentle touch will cause the pin not to retract on it own it just pops right back out applying a bit more push causes it to retract and go into a flashing red alarm state. - With a gentle touch or the alarm state does not stop the z axis movement.
Thanks for your help I really do appreciate it all your doing for me.

Alright, I think there is a problem with your wiring, specifically the white signal wire. Double check your crimps and wire continuity.
-
@Phaedrux I think your right I put two pieces of bare wire and held them together once I let go the z motor actually stop so I your right there has to be something wrong with the wire or so...... Not sure how to trouble shoot it at least on the pcb side of the bltouch i get continuity between grounds and the signal wire on the pcb i don't think this is right but looks like a short I couldn't find a schematic to see how the bltouch pcb wiring looks like?
-
@Phaedrux Bro thanks so much for your help I feel like a super noob and dumb. So I realized that short is not on my other bltouch so hence it defective. I put my other bltouch from my other machine again and wired up to test and z stopped so I guess I will have to purchase another bltouch because it looks like the signal wire is shorted to ground.
-
Glad you got it sorted out.
-
@Phaedrux Thanks for the help once again and sigh... good luck to me to try to get another bltouch during a pandemic....

Well in the meantime if all you want to do is homing the Z you can use probe type M558 P0 to do manual probing which pops up a jog dialogue for you to manually move the nozzle to touch the bed.
-
)))perfect I will do that in the meantime
