No signal on Z endstop terminals + messed up endstop lables
Posted: Sun Oct 11, 2020 2:00 pm
Hello,
I'm looking for help with a weird issue where I get no signal on the Z endstop terminals. X and Y get 5v but the Z is dead. Also on top of that X and Y endstop terminals are switched so I need to wire X endstop into Y terminals and vice versa. Any suggestions on how to fix it? I'm guessing the pin assignment in GRBL is messed up - how should it look to work correctly?
This is an issue only with this shield. My old Chinese shield worked fine (until it died) with the exact same config. I've tested this on 2 Arduino Uno boards so I'm sure it's not a problem with that.
I'm running v1.1h (2019-08-25) release of grbl.
Thanks!
Miron
