spindle activation and endstops

Post by jb.lagrange » Fri Dec 21, 2018 7:30 pm

I received the protoneer rpi-cnc yesterday.
The motors work fine but
1. I cannot activate pin 3 (spn en), either by software (bCNC) or by sending M03.
2. a low level on pin 5, 6, 7 (end stops) does not stop the motors.
Do I miss something ?

The enable pin by default is configured for variable speed or PWM.

After enabling the spindle you need to set the S??? command as well. S1000 is 100% power.

Have you enabled hard stops in GRBL to make the end-stops work?
