Gcode error from FreeCad with DragKnife dressup

[JTV10 (Jason Voss)]

So I picked up a Dog River drag knife so I can make some custom gaskets for motors.

I use FreeCad to design and export the gcode. If I do not use the drag knife dress up on the file the gcode loads in carbide motion just fine. However when I do use the drag knife dress up i get the following error message when I load the file in carbide motion, “Error loading file line 35 arc endpoint error”.

I am not gcode savey and if someone could point me in the right direction to fix the gcode it would be appreciated.

I am running the Shapeoko Pro XXL

Is your GCode exported in Inches or Metric? In most cases, if you are in Inches and switch to Metric, the problem goes away.

EDIT - nevermind, the GCode uses G21, so is in metric.

Okay, it is a G2 (clockwise) arc from:

X35.335 Y75.091

to

X35.560 Y76.200 

which is supposed to have a centerpoint

I-3.585 J1.109

When I draw this up:

The arc doesn’t seem to encompass both points.

Thank you for the response.

I will see if I can fix the issue.
