Tested X and Y stops out OK no prob.
Z stop test:
…‘As soon as you have pressed this button the Z CARRIAGE will move towards the micro switch that your finger is
resting on. Quickly press the micro switch. If the micro switch is working correctly the Z CARRIAGE will stop.
If the bed has stopped the micro switch wiring for the Z AXIS is correct.’
bed?? surely extruder arm/beam
I’ve got different behavior:
Press Z home and extruder arm descends. Momentary press the Z micro switch the motor reverses and go up for approx 5mm and then descends again (call that the second decent) defo. more than 5mm.
If i depress the microswitch again on the second decent then the motor stops straight away.
In a weird way this double hit of the micro switch effectively finds the home but is it normal behavior programmed into the firmware or is the manual is wrong or a wiring problem.
Wiring:
removed the z stop plug (3 terminals middle wire snipped) from controller board.
Put a continuity tester across the plug end terminals and there was continuity.
Press the microswitch to break the continuity
thanks
