Any more recent tutorials? #24

Is work still ongoing with this project? Any further tutorials and explanations available anywhere? CAM software that can handle stl mesh import seems really rare, so this project looks very important. Thank you

PathCAM hasn't been updated in many years, and Xenovacivus hasn't posted anything to Github in 3 years, and that's on his 'interesting stuff' git.

PathCAM has A LOT of bugs. It freaks out over nternational settings(some countries use ',' to separate the fractions from whole numbers, '3,14159' instead of '3.14159' but G-code is supposed to use '.' Gets messy. ) Whatever speed is used is all guesswork. It never seems to be what I want. In some models with holes going through the workpiece it has issues with which side to cut... In one incident it did a 'coarse cut' up to the line, then did a fine cut to clean up the edge of the discard(center of the hole) another, where I had multiple holes, it would cut one 'step down' in each hole before going back to the first and cut another step down...

There's a fork of PathCAM, that was supposed to fix the internationalisation, at least, but that hasn't been updated in years, either.

you may want to look at GrblGru ( grblgru.com ) It's a CAM program, 3D simulator, G-code sender...

Thank you, Norwegian-Gadgetman. Can grblgru do waterline milling of an imported stl file? I saw mentions of stl import in the manul pdf, and I found a youtube video where you slice an stl such that each slice could be cut separately then assembled as a big object, but can grblgru cut the slices together so a single object comes out (like a 3d printing slicer butsubtractive and with absolutely no underhangs). Thanks

I can write up a short manual with information on how I use PathCAM if you're interested.

Here's a video on using PathCAM (for generating isolation traces for PCB's, not quite what you're after):

Some of that translates to generating paths for 3D objects though. Also, looks like the current version of PathCAM only works well with GRBL v0.8 (I think just the pause/resume functionality won't work?) - when I merge the pathcam-gerber changes into the master branch it will work all the way up to the latest GRBL v1.1.
