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.

How to leave small gaps in cutting paths?

I'd like to prevent cut out parts from blocking the plotter. Is there a way to add small gaps in the (laser) contour cuts?

Re: 0.17 & Mac Mojave total crash

I have just tried it: FreeCAD still freezes MacOS, but only for a few seconds. :) It used to freeze the system for about a minute. Also, when I open a file I will get a "beachball" cursor. It is not as bad as a system freeze, but it shouldn't happen (it's the OS feedback of an unresponsive app. Afte...

Array in PathWB

I'd like to engrave and cut multiple objects, one after the other. So far I could not get this to work, as the array feature in pathWB only works on single operations. Is there a way to group operations and apply the array to the group? Also, is there a way to automatically rotates/place as many ins...

Re: Mac dev Py3 / QT5 version - does not start

@looo Thanks for your work on mac OS releases! Your version from the dropbox link starts, but it still has the same freezing issues as the older .dmg builds on macOS 10.14.x.
