I have a machine with two slave steppers on the main axis.
I have slaved X and A and installed home switches on both.
I have set the A axis to linear.
Using manual control the pair of slaved axis move OK and remain in step but:
1. When I use to 'Go to Zero' command, the axis remain in step but move in 'bursts' of about one second/30mm.
2. When using 'REF ALL HOME' the Z and Y axis do the correct thing (touch the home switchs and then back off) but the X and A axis do odd things - one touches/backs-off, the other touches,reverses and keeps going in the wrong direction.
I have very carefully checked:
1. Pulse rate and varied it from 25KHz to 100KHz and it makes no difference.
2. All the ACHIVE_HIGH/LOW, DIRECTIONS, PINS and PORTS.
Any help would be very welcome.
