Re: Post for MPCNC with Marlin firmware

With all that being said, the workaround for the G2/G3 commands seems to be to segment the arcs into several smaller G1 moves - now for my question: Is there an option in Freecad to issue G1 segments in lieu of a G2/G3 arcs? There currently is not. The idea is that such customisations are performed...

Re: climb / conventional

This is also an issue on many of the other tool paths where often only Spiral offers a consistent cut direction. Sadly this is one of the least reliable path options. I have posted about various problems with Spiral and I think this is a well known issue. Perhaps the fact that it is often the best ...

There should be no null shape any more in upstream. Please report if otherwise.
My bad - I hadn't updated in a while. You are correct, after rebasing my changes the exceptions are gone.
Thanks!

Re: Why does App::MaterialObjectPython needs a Shape?

What's the status on this? Is the null Shape property here to stay?

There are quite a few exceptions in Path due to this and I need to know how to proceed.

Re: Dogbone dressup not on one corner

Sorry for the late reply, I created a PocketShape with an extension and I think the result is quite nice. Added a Profile to make sure the square gets milled correctly though. Note that if you want to make absolute sure you can make the extension wider. By default it extends by half a tool diameter....

Open document without showing GUI

I found this old thread: https://forum.freecadweb.org/viewtopic.php?t=17246 and I wanted to confirm that this is still not possible (I looked at ickby's branch and it doesn't seem to be what I'm looking for - although I might not fully understand the changes). The use case is to store templates of P...

Re: FreeCAD and Nomad 883 CNC machine?

If I set millimeters as the units for my FreeCAD file, and then it generates hardcoded the G20 command for inches, but outputs all numbers in millimeters anyway, this looks like a bug to me :D and easy to fix, too. Not necessarily, the centroid controller might require imperial units, and your FC p...

Re: Dogbone dressup not on one corner

I'm not quite clear on what you're trying to do. Maybe have a look at PocketShape and it's Extensions - could be what you're looking for. Otherwise maybe post your file so i can have look.

Re: FreeCAD and Nomad 883 CNC machine?

looks like all arcs are discretized, other than that it seems to be straight forward g-code. grbl does process G2 and G3 commands, so this is a bit of a surprise. If there really is a grbl controller at work you should be able to use bCNC. If there is a modified grbl which doesn't support G2 and G3 ...
