Title: large circles in M3
Post by: orangecrush on March 15, 2014, 01:26:56 PM

I am just getting started with Mach3. Not sure if this is the right place to post this, but I am having a problem with gcode.

I am using Cut3d to generate cutting paths. When the part is cut on my mill I am seeing big circles, which is not the intent. I can also see these circles in the mach 3 window:

The gcode looks fine when viewed in cutviewer:

Reverse your I J setting under Config / General Config.
See if that helps,
Russ

Thanks Russ,

I am not sure I understand what to reverse on the gen config page. Can you point out this setting?
