I'm setting up my CNC (again) I've had some issues with it and my PC. Something has gone haywire and the G-Code is clustered with a bunch of circles over the file I've created. Is this a problem with configuration or my Lic & Software. I do the drawing in CamBam and run G-Code in Mach3. ALSO - My "Y" Axis is stretching the circles into ovals, how do I correct this? My CNC is a 4x8 BLACKFOOT. I just replaced a Microstepper & added UCCNC100 Ethernet interface. It seems to jog OK from the Keyboard, although I think my X & Y AXIS were switched in the PORTS & PINS. So I switched that, Now I'm not even sure how to ZERO the machine. Ugh...any help is greatly appreciated, thank you!

To remove the Crop Circles;  In Config / General Config change the IJ Mode setting. Then Regen the toolpath and all should be well.

Ideally all Gcode containing arcs should contain the correct G90.1 or G91.1 (as appropriate).

Thank you - the IJ setting worked, no more crop circles. I'm still having troubles with my scale. My "Y"Axis is way off, it's only running 60% length programmed, what could be causing that? I should probably post a new thread since my original problem has been resolved. ANYWAY, thank you for the help, I'm feeling very encouraged.

I am pleased that you have sorted the Crop Circles 

If you run the Axis Calibration feature (Settings page) you can check that your Steps per Unit are set correctly for your Y axis (use a reasonably large distance when testing).
