Well, TBT, I am in love with heekscad/heekscnc, because it can output the gcode to carve whatever you can draw. That (when heekscnc is also present) is the missing link, no other cad that I know of, can actually output the code to drive a machine to carve what you have drawn. Most of the commercial stuff wants $500-2500 a seat for the translator package.
However, your repo version shows its a work in progress, not too stable (I've had it go away with no hint of why in the logs several times.) The svs or svn I've pulled in on the previous install of pclos2010 hasn't done that near as often.
But its biggest problem is that its measurement system (when you can get it to work, it doesn't in the version from our repo's, is stuck in metric regardless of the choice of inches in the menu. I have been measuring most physical things in inches for 76 years, and it may be a little late to convert my thinking to the much more sensible metric system. I can recall that 25.4 mm is pretty close to an inch, and that 39.xx inches is a meter, but that's about it.
It's next biggest problem is that the authors haven't written any docs that a newbie might be able to use as a stepping stone to actually learn to use it correctly.
Get the latest heekscad AND heekscnc into the repos, and it is possible it could be just the thing I am looking for. Please? Pretty please, with cream & sugar on it?
I think you have to get both in whatever state they are in today when you pull them. If I bleed a little, its been a great ride so far. ;-)
