Title: Mach3 Turn Help
Post by: ahmedrehan on March 22, 2009, 01:41:28 PM

Following are the problem i am facing with mach3 turn i am using uhu drive.

1. As the tool changer work it changes program coordinates randomly but machine coordinates remains 0,0
2. when any limit switch is hit it changes the hotkey direction with the same hot key the machines move in opposite direction
3. It dose not remember the parameter instead of i save the setting
4. in general configuration should i select absolute or increment?
5. can i have screen shot for general config for lathe.

X0 should be when the X axis is on the lathes centre line, all moves should be in a positive direction. If your X axis homes to the positive then you want to set up a Home Off Distance so that when homed the machine coords DRO for the X reads the amount it will take to move the tool to X0.

 It doesnt really matter which way you have it homing, however  the normal direction would be away from the door. What is important is X0 should be when your tool is at the exact centre line of chuck. All moves towards the back should be positive.
