Dear all, more and more I am flirting with a CNC milling machine. But am I right, that a piece of wood like in the attachment cannot be printed with a 3 axis machine? thanks Karl

I believe it can: no overhangs. Jon On 11/6/2023 9:17 AM, Karl Exler via Discuss wrote: > > Dear all, > > more and more I am flirting with a CNC milling machine.

CNC machines do not print. They cut with end mills.

One thing I do though is put a translate() in front of the make it call that puts it at the center of the printers bed, and the bottom at exactly bed height. I use Cura for a slicer, and its auto placement of .stl's or .3mf's is not always what you want. And sometimes also a rotate 45 on Z if the bed is too small for straight across. Depending on your slicer that might not be needed. >> >> >> _______________________________________________ >> OpenSCAD mailing list >> To unsubscribe send an email todiscuss-leave@lists.openscad.org > > _______________________________________________ > OpenSCAD mailing list > To unsubscribe send an email to discuss-leave@lists.openscad.org Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

ggg... of course I know how a router works... "printing" happened due to too fast writing. cutting out of wood was that what I wanted to write Am 6.

Yes, of course this could be cut --- it would be trivial if you have a V tool which matches the desired angle. If you wished to do it as 3D, then you would export the STL from OpenSCAD and then use a 3D CAM tool such as Kiri:Moto --- note that this would require cutting deeper than the bottom of the stock by the radius of the tool used. If you're willing to use Python in OpenSCAD: http://www.guenther-sohler.net/openscad/ then you may find my project, gcodepreview of interest: https://github.com/WillAdams/gcodepreview which is all about how to model 3D parts as if they were cut out using a CNC --- while it can directly output G-code, that (and to be honest the entire project) is still quite primitive with limitations such as not having loops set up for iteratively cutting down and setting Depth Per Pass on a per cut basis. What sort of projects do you wish to do? How do you wish to approach them? William -- Sphinx of black quartz, judge my vow.https://designinto3d.com/

But why bother, you could do this on just about any table or chop saw in well under 10 minutes. And probably cleaner. And that includes selecting the scrap off the pile under the chop saw table and marking it up for the cuts. I can do it either way, but writing the gcode would take at least a week. A 4 or 5 axis machine would greatly simplify the gcode. Both of my mills are 4 axis. > > Am 6.
