Anyone got any idea what I am doing wrong here please? I have only just finished calibration on the Maslow and trying to cut a few things out this week a a tester. The letter with 4 passes works fine in Fusion 360 but looks bizarre in Ground Control, I guess I am missing some setting somewhere but it is not obvious to me what it is.

What is the version number of Ground Control you are using? We had an issue like this in the past which was fixed, maybe this is related.
Will you post a copy of the gcode file?
I did a basic rectangle and the same thing happens, thought that would make it easier to analyse the GCODE.
Ground Control version is 1.26
I should mention that I can cut the sample GCODES that came with Ground Control with no difficulty.

What is the post-processor you are using in F360?
Did you try this one? fusion360-post-processor-for-maslow
bCNC and Camotics also display a strange views and the small circles are vertical.
This is in the CAD/CAM workflow. Try the Maslow post-processor or alternative Grbl, Linux-CNC, Mach3.
Kind regards, Gero
Edit: G19 in the code!
G17 is XY plane, G18 is XZ plane and G19 is YZ
Edit2:
I took out the circles and some strange zig-zag, plus the G19 from a different plane, corrected 2 wrong x-coordinates and removed all ->â:â<-.
This is what a simple rectangle looks like:
it might be best if you share the fusion file for that rectangle, that way someone can look at it and see where the problem is. Iâm willing to bet something isnât set up quite right in the cam settingsâŚ
you keep saying you are using a simple rectangle, but based on the g-code, itâs doing a rectangle with rounded corners (and generating the wrong g3 lines for those corners)
they look like a reasonable radius, but with the center in the wrong direction.
OK, what dlang said there made me go back through some autodesk forums and I finally figured out that I was being a bit of an eegit and hadnât noticed that it was set to ârollover cornersâ in the passes section instead of âkeep corners sharpâ.
Thanks for the replies, onwards and upwards, will post pics of project when it is done.
