Delta Laser GCode going in strange directions

Sorry if its against the rules to crosspost but I don't know how many people visit the laser cutting subforum.

Is there a missing G-code command I need to use when exporting a gcode file using J-techs Inkscape Plugin? My Delta moves in strange directions (ie down towards the bed) even with simple gcode directions


Heres the beginning of one of my test cuts (too long to post it all but the sequence fails immediately):
I manually home and set the zheight to focus the beam

ok so i think i narrowed it down, it seems to mess up at G3 and G2 commands, which i thought were supported by marlin. Any idea how to enable these commands? or do I have to switch to a different program so that arc commands arent sent

... export the arcs in linear segmentation, then it should work ...
