ger21 - I use Vectric VCarve Pro for my router.  Is that what you mean?

I have a similar problem with my router gantry.  It is built on 25mm ballscrews that are 1500mm in length.  One side travels just slightly more than the theoretical 5mm pitch.  The error is very small but accumulates over a long cut.  At one end of travel the gantry is slightly out of square.  I have reduced the error by making sure it is square at the center and splitting the difference seen in large parts. Or by setting the material up close to the machine zero to minimize travel.  It would be a very nice addition to Mach3 if separate steps/unit travel could be assigned to accomodate small mechanical differences while retaining the other properties needed with a slaved axis.  Post processing editing to assign movements to each axis is out of my league right now and may not be supported by the G540 controller I'm using.  If anyone knows of a patch to enable such a feature that would be really helpful.  Right now I am trying to calibrate each ballscrew on the machine to see if the z axis screw is a closer match.  Wish I had thought of that prior to building!

Hi.  My name is Travis and I am new to CNC but have just built a 4 x 4 ft router.  Running mach 3 and cut2D.  This is my latest project with no real purpose in mind.
About me:  General Surgeon in NC.  Spend a lot of time on call and having to stay close to home.  i use this time to do projects such as the router.  Other hobbies include long range shooting, reloading, varmint hunting and xbox.  My wife allows me to live in the garage with lots of stuff to keep me busy when I am not at the hospital   I look forward to picking the brains of the forum users to further my knowledge of Mach3.  - Travis
