Thread: PWM output on CNC BOB
Threaded View
- 
	09-05-2021 #19Here are my hal and ini files (I had to rename them as txt files to get them to upload). 
 
 The limit switches are all connected to machine ground except when they are pressed.
 The estop switch is connected to ground if the machine is on, except when the button is pressed.
 
 The steppers will all jog OK in stepconf. When I select an axis to test in stepconf, the BOB relay comes on (WHY?). When I run linuxcnc, the orange ON button is greyed out, even if I invert the estop input.
 
 Should the limit switches and estop switches maybe be pulled high with resistors?
