Whenever I attempt to use the drag knife addon for fusion with my Nomad 883 I get several “Arc Endpoint Error” messages when carbide motion attempts to load the g-code. I’ve updated carbide motion to the latest version and fusion 360 is up to date. I’ve used this plug-in before with no issues and I’m not sure what’s different now.
I’ve attached the g-code if that’s useful.
"Error on line 286: Arc Endpoint Error "
Also get the same error on lines 350, 402, 433, 438, 609, 757, 772, 787, 797

Which post-processor are you using?
Do you have the output set for metric?
It doesn’t plot correctly in one 3rd party tool:
G1 Z0.0424 F13.333
G1 X0.338 Y0.107
G2 X0.349 Y0.116 I0.010 J0.
If we draw this out:
reducing the circles, but maintaining their center:
We then draw in the center:
and we see that things do not line up:
Ok that makes sense. so the drag knife specific post processor is doing something wrong?
Is that something I can go in and manually fix?
It’s a math issue.
If you set the post-processor to use metric dimensions that reduces the size of the error and may get it small enough for it to work.
