General Mach Discussion / slaving

« on: February 02, 2015, 09:25:06 PM »

 
Hi Everyone
I am very new to the cnc / Mach3 world about a month.
I am building a cnc router that has two stepper motors on the same axis.
I have read the instructions from Mach3 and in this case slaved my y axis to the A axis, no problem.
Both motors turn in the same direction but they are not in sync with each other.
I have 2 home switches on each side of the gantry, according to the instructions when I zero the Y one side of the gantry with hit the home
switch, stop and back off and the Y does just that but the A hits its home switch and keeps traveling.
I have tested the home switches by the LED's on the diagnostics screen to confirm they work.
Can anyone please help ??
Thanks Richie.
