Couple Questions related to the 8L: Assume you are standing in front of the lathe, with the spindle on the left hand side.
1) When homing the Z axis, does the carriage go to the left or the right to find the home sensor?
2) When homing the X axis, does the carriage go away from you (back of lathe) or to you (front of lathe) to find the home sensor?
Depends on where the home switches are. Home normally would be in the right rear position.
3) When you press the left arrow on the keyboard, does the carriage (Z) go to the left or the right?
Carriage should move left,
4) When you press the left arrow on the keyboard, does the DRO number for Z go up or down?
Z moving in the negative direction (counting down)
5) When you press the up arrow on the keyboard, does the carriage (X) go to the back of the lathe or the front of the lathe?
The X carriage should be moving to the back (away from you)
6) When you press the up arrow on the keyboard, does the DRO number for X go up or down?
The X DRO should be counting up
This is the case for all lathes.
X G54 zero is normally tool tip on the spindle centerline. Z G54 zero is normally tool tip at the right end of the part.
