General Mach Discussion / y axis problem
« on: May 09, 2012, 02:21:55 PM »
I am having a problem with my Y axis. I am trying to cut 2 small parts out of aluminum - 3/4x 1. Mirrored so there is a left and right. I have the Gecko 540, a taig mill, I use Rhino and Rhino Cam for cad/cam generation. This is not a new set up I have been using the mill for more than a year.
When I first ran the program for the exterior profile, the Y axis looked like it was loosing steps in the +Y direction. The cuts keep creeping towards - Y. the X axis is working fine as is Z. I stopped the program before it could cut both parts. I replaced my power supply and stepper motor. I reran the same program in wax letting it cut both profiles. It steps toward -Y on the first piece and then towards +Y on the 2nd piece. On the Second piece the steps are reversed.
I rechecked the Rhino Cam Paths and regenerated them, deleted the original file in Mach and transfered the new file and its still doing the same thing.
I have another mill with a seperate controller/computor,I took the same file loaded it into Mach and it runs fine. No wierd stepping.
Both mills have dedicated computors and controllers. I do my cad cam on a seperate computor.
ANy thoughts?
