I'm back again after long time..
I have some information, if you have EMC2 to run your CNC. So you can try Heekscad and Heekscnc.
I have try for a couple days, and it is run very good.
Some information about Heekscad
- free opensource
- read 2D file (dxf) then convert to gcode
- 3D drawing
It is enough.
