Y axis Jogs when homed but won't actually home
-
I had to disassemble my printer for a move, 6 months later, I tried to re-assemble it/get it up and running. I'm running into a problem where when I attempt to home the Y axis it jogs but never contacts the homing switch.
I've completely updated all software, re-compiled the firmware from scratch, tried with and with out limit switches, and different motors. nothing seems to make a difference. I'm stuck, I'm running the most current software as of June 20 2021 Here's my config g

@bellus check the state of your y endstop when triggered and not triggered using M119. I suspect you need the pin inverting
-
Endstops - X: at min stop, Y: at min stop, Z: not stopped, Z probe: not stopped
X is contacting the limit switch, Y is not.
-
@bellus if the state isn't changing when its triggered then its a wiring issue
Endstops - X: at min stop, Y: at min stop, Z: not stopped, Z probe: not stopped
If the above is when not triggered you need to add a ! to the pin name
-
@jay_s_uk pressing the switch, M119 reports the same. I think it may be wiring or switch related. May have been damaged in the shipment, prior to shipping it all was good but on older software.
-
@bellus what type of switches and how do you have them wired?
-
@jay_s_uk, Oh man, they were the end stop switches that came with my original printrbot simple. 3 prong, 2 wires, normally open switch. they've been wired the same way for about 2 years with no issue. molex connector on the y stop connector on the board.
-
@bellus I suggest you methodically check your wiring etc.
Normally open switches are susceptible to EMI (electromagnetic interference) leading to false triggering etc. The pin names should be configured with a ! for NO. The other drawback is that if they fail, your machine will continue to try and home.
Normally closed are much better. They are less susceptible to EMI and if they fail, the printer won't try to home (the issue you're seeing above)Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
-
@jay_s_uk, I'll give that a try, really appreciate the help. I'll follow up once complete.
-
@jay_s_uk That was it, that switch was about 7 years old, guess I got my moneys worth...Ironically I had half a dozen NC switches laying around.
Swapped it out for a new one and it homes nicely and M119 reports accordingly. Thanks again, was really thinking it was something more severe, been a minute since I messed with the software. -
@bellus glad we got you sorted. shout out if you have any more issues
