Hi, I’m a new KiCad user.
I wanted to generate (plot) gerber files for our lab’s old PCB milling machine (at least 15 years old), which I have to work with a pretty old proprietary CAM software to operate.
Now the problem is, although the CAM and KiCad both claim to support RS-274X format, the CAM is not accepting gerber files generated with KiCad, raising an error on import.
I did a bit of fiddling around, and I found out that, a gerber file with G01/G02 in G36~G37 block is not accepted, while a gerber file without G01/G02 in G36~G37 block is accepted. An example of G36~G37 block that is accepted by the CAM is:
Apparently the gerbers that KiCad generates have a lot of G01/G02 in G36~G37 block.
I also looked at the contents of gerber files previously generated with Eagle, and it contained no G01/G02/G03 in G36~G37 block. All arcs were approximated with massive amount of line segments.
So my question to the community is: how can I make KiCad not to use G01/G02 in G36~G37 and instead force to use linear interpolation?
I understand this is a problem on the CAM side, not KiCad. However I thought it would be easier to solve it on KiCad if it is possible.
Thanks, and pardon my broken English.
