Z axis going the oposite way it should.
« on: October 23, 2007, 08:09:34 PM »
My Z axis goes the opposite way it should, I always have to switch the values around to make the code work. Can this be fixed in Mach3 or is there something I'm doing wrong when I set up my CAM program to make the G-code?

Z- should be making the tool go deeper into the part. If you jog in a negative direction, is it going deeper? If not you can change the motor direction in config, homing and limts. Reverse the z axis.

You can reverse the axis in the Homing and Limits page, you will find it under the config menu.

If I press "page down" on the keyboard the Z axis goes up, if I press "page up" the Z-axis goes down.

Thanks, I'll check that out.

Does your spindle go up and down on your machine or your table?

OK so if you press the Pg Down your spindle should go down and your DRO for the Z should increase in the  negative. Is this happeneing?

Hi, mac102004

In Config, Home & Limits there is a Reversed Box for each Axis, Check it for your Z Axis.

Hope this Helps, Chip
