z axis calibration
Hi Steve, My first print turned out just great using your software. I've run into a bit of a problem on the z axis calibration. I've attached some pictures. There seems to be a drift as the z axis distance increases, is there a way to do fine adjustments? or is this a firmware problem? I'm using the Uncia

Re: z axis calibration
Can you determine how much it's off by?
Start at a position, and move the z axis 100mm using the software. Measure it and let me know how much it's off by.
Thanks,
-Steve

Re: z axis calibration
dangre, the problem was that CWS approximates the Uncia's steps per mm to be 90, when the actual value is closer to 87. I posted a recompiled version of CWS that had the correct value on the Uncia Google Group.
