I did go to the Alibre site but they only have a 30 day free trial, which includes legal threats daily for about 2 years if you don't buy it at $500/seat. BTDT, deleted it when it no longer ran. I tried that once but 30 days is nowhere near enough time to get your head around it and decide if it can do what you want to do. I eventually wrote a procmail recipe to send their legal threats to /dev/null. OpenSCAD is a breath of fresh air, easy enough to use, and gets a new AppImage release about every 60 days. Updated for newer compilers, versions newer than January of this year need buster to run so won't run of this stretch with 32 gigs of dram. So I run it on one of my old dells with buster and 16gigs of dram. But it really needs more dram. Big projects with lots of union()'s and difference()'s eat memory for all three meals, putting it deep into 50 gigs of swap and of course that slows it down even if the swap is on its SSD at 900 megs a second. But it does get the job done if the job is an .stl to feed cura, hence to a prusa MK3S kit I built from a box of parts, took me 3 days to build it. But openscad does not have a library that can generate gcode that I know of, so I still write my own. John's tripod crank fixings would be a couple hours to rough out & 3 days to fine tune for "purty". :o) Probably done on my 6040 since I have a mister on it. Haven't packed a mill and broke it since. :) Take care Marcus. > > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
