Has anyone used this software with success? I am getting “i” and “j” coordinates in my gcode file that I do not believe GC can handle. See below. If anyone knows how to update this program to prevent this, please advise.

G2 and G3 gcodes are arcs, with the relative center determined by I and j. The file should run as expected, though because of some quirks of floating point math in the Arduino software, arcs with really large radii will be cut as straight lines. The firmware will indicate when it is taking that action, in practice the difference between the arc and the straight line is indistinguishable.
Thanks for responding!
So you say I do not have to worry about the GC recognizing this then? I tried importing into Easel to view and it did not like it at all so I assumed QC would do the same.
Unfortunately I do not have internet access where my Maslow is set up so any changes using the web based programs makes me truck up to the house, redo everything, then go and test. Very time consuming…
I think it will run just fine. You could run it without a bit in the router to ‘pre-flight’ it, just to see.
I will do that. Thanks again.
It worked… GC received and ran with no problems. It noted that the system replaced some large arcs with straight lines to improve accuracy, but overall it ran great.
The Makercam software is far superior for my needs than the Easel software. I really wish that it could be further updated to allow for user preferences to be saved. Makercam does have it’s bugs, but nothing I can not work around. One bug that I noticed involved importing objects with an ellipses inside the part (window cut out). If I import the SVG into Easel the ellipses are perfect, If I open same svg file in Makercam, the ellipse turns 90 degrees.
