Mechanical switch for z probe
May 21, 2017 03:22PM
Hi

just installed the duet 0.85 (non wifi) on my mini kossel and i have a mechanical switch probe, so the original setup was the two outer tabs on the switch itself.it triggers obviously when the switch was pressed is that correct? , because i thought it would be the other way around ie once the probe lifts of the switch then it be triggered, because i wired it differently the outer tab to the middle nc i think its called i get mixed up and i go do a g30 and soon as the switch goes the board shorts thankyou for any help given can't wait get this sorted don't worry it will be moved over to a sensor once i have funds spend on it thanks again

How have you connected your Z probe switch to the Duet? If you connect it to the E0 endstop input then you must use the two outer pins of the endstop connector on the Duet, regardless of which switch contacts you use.

I think you must have a short somewhere, perhaps to the centre pin of the E0 connector.

I thought i would be able to replicate the issue by just pressing it and checking the status, i would of thought it would do the same wether i send a g30 or not but function fine when i press it, it only
reboots during a g30 command which is odd i did check the wiring nothing untowards ill just have to wait and get a ir sensor lol but it just baffled me been over it and over it

Yes that does sound odd. Which firmware version are you using?

Bit of progress i did another configuration using tool again and thought id just do the the calibration find nozzle height just in centre as to see where about roughly it is. I did the g30 s1 command went down and stopped nothing reset or looked as if it was shorting out, so i homed and did the g30 went down really nothing happened as before, worked fine, defiantly a weird one that is
