Re: ProfileDepth Problem

It is my understanding that the profile operation cuts to the bottom of the job and that is how its worked for me in previous versions of Freecad is this wrong.

Re: ProfileDepth Problem

Should I do a bug report No! It seems likely from your descriptions that you are a fairly new user to Path Workbench, so there are some things for you to learn. Firstly as Herbk mentioned, the auto calculate of expressions {edit: usually do not occur} until you "after recalculate the path, not dire...

Re: First attempt to use Path - Error

I use FreeCAD grbl post processer a fair bit with an Arduino mega and also today an Arduino pro mini and on a few occasions for LinuxCNC. Works great. Re your question is Path just a CNC emulator - like a flight simulator - or is it supposed to actually control a CNC to make things? I strongly sugge...

Re: Path array wiki page

2. Add the path along which you want to create the repetitions to the selection I think this step should be ignored and deleted from wiki as it makes it sounds like you will place or sweep the path array along some other path. For me ignoring step 2 (because I forgot what wiki said) and just treati...

Re: Drill Retract Height - Issue?

My understanding from the nice diagram in Path Commands section on wiki page https://wiki.freecadweb.org/Path_Workbench is that OpStartDepth = height of the top of your stock.
