RE: Bltouch Configuration Issue
@Phaedrux Thanks for the help once again and sigh... good luck to me to try to get another bltouch during a pandemic....

RE: Bltouch Configuration Issue
@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.

RE: Bltouch Configuration Issue
@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?

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.

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

RE: Bltouch Configuration Issue
@Phaedrux after applying a g30 i had the pin press the bed slowly but it did not retract i pushed a bit more and it retracted into alarm state

RE: Bltouch Configuration Issue
@wepaking If i pull the pin manually and push it back in it doesnt retract automatically and it also does not go into alarm either.

RE: Bltouch Configuration Issue
@Phaedrux Send a M401/M402 command works with retract and deploy but if i touch the bltouch gently when it is deployed it will go into an alarm state.

RE: Bltouch Configuration Issue
@Phaedrux I cant seem to attach the images
I gently put my finger on the probe and it does not retract if I push more then it goes into alarm mode using the M280 P3 S10 I1 OR S90 same thing occurs I wil also look into the link you provide thanks as well.

RE: Bltouch Configuration Issue
@PaulHew I looked into this I don't understand what I should be doing. I can't move the axes in the web interface unless it homes in allah ces first I am not sure how to move it without homing and I don't get where the trigger height will go or what it does for the bltouch I thought once the probe retracts it take it as detected and then I can babystep and set my z-offset. Sorry for the bother just trying to understand what step I am missing an an example g1 command will be cool.

@DIY-O-Sphere I'll try setting it lower I was playing around with the values and it just does the same thing it won't trigger.

Bltouch Configuration Issue
Hey everyone new to the duet family and I am trying to install a BLTouch on my printer.
I have tested it with the M280 P3 S10 I1 and M280 P3 S90 I1 and it retracts and deploy as intended but when I do the z homing the testing the pin it deploys the probe but once I tap or hold it with a solid surface it goes into an alarm state and the z motors does not stop. I am stumped.....Here what I have tried
- In the z probe on the duet web viewer I see a 0 regardless if it retracted or deployed. If I unplug the both the zprobe in and ground it goes to 1000 as intended as if the probe retracted. I put the pins back it goes to 0.
- I tried a working bltouch on my other machine and it does the same thing it always 0 and won't go to 1000 until i unplug the zprobe connections.
- I have installed my servo wire to pin 8 (heater 3)
5v and ground on pin 1 and pin 2 respectively
Connected the white and black wire respectively in the zprobe In and GND connection
I am not sure what else to try it just wont home z and recognize the probe the biggest issue is it just go to alarm mode i presume it reporting some type of issue.

M280 P3 S90 I1 ; retract BLTouchAny help will be greatly appreciated really been trying these past two days to see if there anything wrong on the hardware side of things but I cant see to find out what my problem in either software or hardware. I used to reprap config tool to generate my configuration everything works expect the bltouch.
