i think, if it’s suitable for a reprap there could be quite some interest from there. I have access to a (not yet fully working) repstrap. (i think it’s called so) Could do some tests if your G-Code is working on it, once your G-Code is more than G00, G01

as I stated in the first post, I won’t be doing the code for 3d printers, the addon works with 3 axis milling, however could be maybe used also for tangential knife or something similar…
ok. I got access to a 3 Axis MiIlling as well. Currently “driven” by mach3. If it would suit you to test the code there, just pm me.
Actually, it now exports Mach3 code, so yes, that can be tested allready. However you have to switch spindle manualy, best is to test the mill without doing any milling actually, ‘in the air’.
I have also 3 axis mill with Mach3, that’s why I wrote first exporter for mach.
Also - if you start testing, best is to start with curves and cutout, like cutting e.g. plywood, that now works the best…
another important thing - units are 1blender unit = 1m, be aware of that! large object can take ages to compute, and could exceed your mill limits.
Just want to let you know about a new update of this - 0.2.2.
