hello
i have a problem with dividing head (A AXIS) machine is vmc FANUC 18M
when i switch on the machine all axis goes fine to home position XYZ&A
No (APC) provided with the machine. the problem is after switch off the machine and next day i zero return the axis as usual the A axis gives me error about 10 degrees comparing with the previous homing position,
so if some one could tell me where is the problem and how to fix it
for example, do i need to set zero reference for A Axis ? if yes what is the procedure??
any help will be appreciated
thnx
