Re: 0.17 & Mac Mojave total crash

I was using the latest 0.19 dmg release from git. Let's hope apple doesn't remove OpenGL with the gm/final release.

Re: 0.17 & Mac Mojave total crash

I have just tested a beta of macOS 10.15 catalina. It is still possible to run FreeCAD - so hopefully we can safely upgrade :) You just have to do a few more clicks to make it happen.

Re: How to leave small gaps in cutting paths?

Sorry for answering so late, and thank you for your efforts! I am quite busy and have been trying to get this working :/ I have already deleted the .FCStd file. The problem should probably not be 'hacked' in a modified postprocessor anyway.. there are many settings and things that would still output...

Re: 0.17 & Mac Mojave total crash

Is it really necessary to sign these bundles? As far as I understand, there's no way to get these bundles to work on Catalina (the next macOS release, 10.15). Also, every Mac user will be nudged to upgrade the OS (and so they do) and new Macs won't be able to boot older macOS releases. I hope Apple...

Re: How to leave small gaps in cutting paths?

Thanks for your help! Here's a simple 10mm square to be lasercut with holding tags on each edge. square_freecad.txt is what i get out of freecad using grbl postprocessor. square_laser.txt is how I would modify that file to make it work on a lasercutter. The holding tags are too big in this case beca...

Re: How to leave small gaps in cutting paths?

Hey, thanks a lot for hacking that -noZ option. I'll try it. For my current 'workflow hack', to get holding tags for lasercutting, I have to use the Z changes as a source for "find and replace all" in a text editor. I am placing the holding tags with some odd Z number, 90deg. Then I'll search and re...

Re: How to leave small gaps in cutting paths?

@chrisb This does not work with lasercutters - often times they don't even have a Z axis (and if they do, it is used for focusing). The laser has to move without being turned on (G0) to leave gaps in the material. Alternatively you could travel faster in xy and/or reduce the laserpower to leave an "...

Re: How to leave small gaps in cutting paths?

I'm running grbl 1.1f on an arduino, so I have set the Processor to grbl in FreeCADs job settings. If that is the postprocessor you are referring to?

Re: How to leave small gaps in cutting paths?

I don't think I'll be able to help as I can't code. The tag feature doesn't work for laser/plasma/.. other cutting tools as well. It would require a G0 movement instead of Z changes. I will try to edit these by hand, too :/

I'll have a look at the code though, once I have spare time :)

Re: How to leave small gaps in cutting paths?

Hey Mark,

thanks, that seems to be what I was looking for. I'll give it a try :)

Also, is there a way to remove the third axis in gcode? I am removing gcode manually in a text editor for now.
