General Mach Discussion / Travel diestance does not match command
« on: June 02, 2011, 05:18:57 PM »
I am working on a small converted lathe and am turning only wood till I get this figure out. I break fewer tools that way!
What I have done:
Went into the motor configuration and set my step rate to match the actual travel. When, I jog my x axis 1 inch, it moves 1 inch (measured with micrometer) and the display on mach shows that my x has moved one inch.
I have run the turning wizard to just turn the OD of a part from .70 to .60 (love the wizards btw.) I get everything lined up and zeroed. I run the gcode that the wizard has generatred and then measure the part when finished. It actually is moving 2x the distance it is supposed to. It measures .50 when I finished my run instead of the .60 that it was supposed to measure.
The Z axis has the same stepper motor and same pitch lead screw and the controller is set the same and it does move the proper distance when running the program.
This is probably a simple fix but I have been reading and looking for 2 days and have not solved it yet. Can someone lead me in the correct direction?
