But I think that last line about sheetcam users is a shame. gcode is where the cutter meets the cutted, and you can't get much closer than that. OTOH, the higher level stuff lets you concentrate more on the artistic aspects as the math is being done for you, so I imagine it balances out, possibly in favor of the artistry when looking at the accounts receivable if the design package allows that. I get the impression there isn't room in some packages for the artistry of what the composer is seeing in his head. At some point the expenditure of the composing machines cpu cycles becomes less important than the wall time. Particularly so if the wall time is reduced enough to pay for the license. I've downloaded that latest freecad-0.17, but its 64 bit and this is a 32 bit install, so the best thing I might try is to go fire up a rock64, which is stretch on arm64 with 4 gb of dram, 60 GB of SSD and see how it works there. That might take a trip to wallies for some net cable, as that cable is now hooked to the old HF mills computer, and a shorter cable would reach it from the garages switch just fine. I found the learning curve pretty vertical the last time I tried .14 on this machine, and combined with a lack of stability, nuked it as not being worth the effort to learn. Probably mostly my fault, old dogs, new tricks syndrome at its worst. But I can't seem to get away from the fact that this wet ram /is/ 84 years old, and has survived a couple attempts to get shut down now, each of which has had its cost.
