@Phaedrux do you have any idea why the first two pwm channels failed?

i would really like to know if i should be worried about the other PWM channels. has this happened before?

UPDATE
i saw that the leds are on for e2 through e4 heaters on the duex. i dont remember them ever being on. so i decided to try e6heat on PWM5 and it works!!!

does anyone have any idea how the pwm could fail like that? i see the heater 5 led is on now, but not full brightness like the others.

video of scope, i press deploy probe at about 17 seconds and retract at 23 seconds. it keeps flickering like this untill i turn off the printer. this was with no wires attached to plug, just the leads for the scope
i thought i would have to record it and go back to look for a single 650ms pulse, but it seems to keep going? does it keep trying untill it sees a change in the hall sensor wires?
the pulse lengths seem good, but it seems very noisy.

@DIY-O-Sphere nice, time for some testing

@DIY-O-Sphere the jumper is for the 5v power to the probe, that is fine.

@dc42 do you know the pulse length for the pwm signal to depoly and retract the probe on PWM1 on duex? i have an oscilloscope i can hook up. it seems as its not sending the signal anymore. and also is it supposed to be 3.3v or 2.5v? and does it go high or low to deploy the probe?

yep, ive been printing smoothly since may.

@DIY-O-Sphere so that would make sense that the duex e2 heater led is on, but i wonder why 3 and 4 are on.

@DIY-O-Sphere connected to PWM1 on duex

@DIY-O-Sphere something at add, im not 100% sure, but i dont remember the leds being lit up on the duex e2,3,and4 heater teminals...maybe they were, idk. but it seem like they shouldn't be.

its been a while but you cant with the duex expansion ribbon installed correct? dont the servo wires plug into the large expansion heaader?

i should clarify that i mean the signal wire for the servo wires, not the signal for bltouch prob position.

@DIY-O-Sphere i tried that and still no dice, i mean i dont see how that could be the issue if its been working since may. i dont fully understand how all of that is supposed to work, but it was working whit the config as is.

quick recap
-haven't touched config in months
-bltouch is confirmd good
-wire harness shows cont on all wires from duet to probe plug and a strong 5v and 2.5v to the probe
-tried changing line 57 to duex.e3heat and tried pwm2 plug on duex
-noticed that my other printer on RRF2 the signal pin is at 3.33v and this one is at 2.5v (the signal to deploy the probe, not the hall sensor signal)
-DWC2 says zprobe 0 whether i manually pull the pin down or up.
-am confused...

yeah, it just does nothing, everything else is working except the deploy and retract of the probe, if i pull the probe down manually the red light turns off but there is no blue light. also i though it should flash red if you pull it down manually?

just measured signal voltage on my other printer and its yellow signal pin is at 3.33 volts, and this is at 2.5v. does this matter?

just tested the other bltouch and still no deploy. is there a way for me to know if the duet is physically sending the deploy signal on the pwm signal wire? should be the left pin of the three? i edited the other reply but i do have a good 2.5 and 5v to the bltouch.

and to switch pwm output i should only have to change duex.e2heat to duex.e3heat for pwm2?

@Phaedrux i just actually checked each wire individually with a multimeter and all show continuity, so i guess i can try a different servo output on my duex, maybe something happened. other than that idk, maybe the bltouch died but still self tests? i have another bltouch on my other machine, but i really dont want to take it off to rule out the bltouch unless thats my only option. and i also just double check that i have 5v and 2.5v out the end of the harness

hi all, ive had a printer set up and running smooth for a few months and today the probe wont deploy for anything. the wiring seems to be intact. i have a duex expansion board and the servo output is on its pwm1 pins, i noticed the 2.5v signal wire doesn't change on my multimeter when i send a deploy command. im not sure how quick the signal is but i assume it should go high to 5v? also that was with no wires attached just measuring from pin to gnd.

i should add that it still does its startup routine, i literally printed something yesterday and now just nothing, is there a way to rule out the board in my diag?

damn, got my hopes up. i tried that with !, ^, and !^ on the pin name but still nothing. here is a refresh of the config.
