General Mach Discussion / Motor Tuning Problem

« on: September 01, 2017, 11:57:04 AM »

I am having a little trouble with the motor tuning.  The x and y axis do not seem to hold their calibration settings.  I thought they were calibrated perfectly, then I cut a simple 16" square and one side is almost .125 larger than the other.  Re-calibrated and once again one side is slightly larger than the other.  I first used a standard tape measure to calibrate at several different distances and then after that was dialed in I used a dial indicator for fine tuning.  Any suggestions?

Unfortunately, one more issue if you don't mind.  The x and y axis do not seem to hold their calibration settings.  I thought they were calibrated perfectly, then I cut a simple square and one side is almost .125 larger than the other.  Re-calibrated and once again one side is slightly larger than the other.  I first used a standard tape measure to calibrate at several different distances and then after that was dialed in I used a dial indicator for fine tuning. 

Thanks in advance!

That worked.  I am new to Mach 3 - my previous CNC had proprietary control software and not so many variables to deal with.  Would it also be a good idea to increase the acceleration?

Thanks for the quick response!

General Mach Discussion / CNC Router not cutting all square outside corners

I just finished setting up a Chinese Router and was doing my first test cut.  It was a simple Rectangle with square outside corners.  I sue V carve pro and the G code seems to be fine but 3 of the 4 corners were rounded.  Anyone have any ideas?

Thanks
