Here’s a link to the modified post processor I have used: Is that even possible on a Marlin based system? Would that depend on the g-code sender?
Haven’t tested yours out, but was wondering if yours can pause for tool changes. I still don’t have my machine cutting yet, but have done a few simple tests with a pen, and the g-code produced by the post processor I have seems to work OK. I just compared the output of your script to the one I have, and noticed some differences in the length of the file, probably just caused by using different tolerances (yours is longer, so I suppose it makes smaller moves). I made a few adjustments so so that it zeros the machine at the start and sends it back to zero at the end. I found a post processor for Marlin a while back (link not included as comment won’t post), which seemed to work reasonably well, but tried to home the machine (as a 3D printer would) at the beginning of a toolpath. Pronterface reads comments with a semicolon “ ” rather than the “/”. tap, but then the comment syntax causes an error (" raw G-Code line “/” could not be parsed"). This is not so important, as Pronterface can read the. I use Pronterface, and it wants a “.gcode” file extension, where this post processor outputs a “.tap” file. Just tried it out briefly with one of the CAM examples in Fusion 360. Question was asked about post process file
