I wonder if I am missing some setting...
As I mostly do text based wooden signs with my router, I really never put much effort into getting the axis's super accurate, I just used a 24 inch ruler and estimated...I recently rebuilt the machine to gain Z distance and increased stiffness...anyway...(I have done this several times)...I can get the X and Y axis to repeat +/- .001" measured by an electronic digital caliper, over a 5" range...now when I cut a 5" circle (gcode generated by VCarve)...the circle ends up about +.032" across the X and +.044 across the Y...not really sure if something else is going on...tomorrow, I will cut some squares and measure...
A couple of questions...I read somewhere that you MUST re-home an axis after you use the calibration routine...True?
Also, If I can cut say a 5" square and end up with (tool diameter compensated for) 5.030", can i just go into the axis calibration and say to move 5", then enter 5.030? THis is what I will try tomorrow, just did not know if there was some other config setting that may be creating the circle errors...
Thanks
