[Emc-users] openscad to normal gcode converter?

Greetings all; What do we have that can convert a .stl file into gcode for a mill or a lathe? I think I have the 4 internal pieces ready to install in some sort of a housing, so I ordered a couple hacksaw blades for my bandsaw and bought some 2" thick alu bar for the output side of this thing.

Fusion 360 will convert a stl into gcode. It will take a bit of compute power to do it for a large number of facets stl file. Dave On Sun, Mar 21, 2021 at 1:14 PM Gene Heskett wrote: > Greetings all; > > What do we have that can convert a .stl file into gcode for a mill or a > lathe? > > I thi

I looked into this and have the trial version. I'm currently using AlibreCAD and the now discontinued AlibreCAM with 4 axis support. My costs are way more than the $495 Fusion for that and it appears to offer 4 and 5 Axis CAM support. Also PCBs and Schematics for which my renwal costs have n

Can OpenSCAD export to .STEP files? If so then the design is exportable to a wide range of CAM software for toolpath generation.Fusion (free version) can import STEP and produce toolpaths but isn't this housing simple enough for hand-coding files? On Sun, Mar 21, 2021 at 10:14 AM Gene Heskett

So. interesting.. I just swapped the gears.. Before my ratio was 100:1. Input scale was 1600step/rev * 100 = 16/360 = 444.444 input scale. Now I reversed the outside splines. I thought - wow - I must be losing steps - but i would aways come back to zero. Finally though - may

Re: [Emc-users] openscad to normal gcode converter?

So it is not a "real" .STEP file?STEP should preserve the lines and arcs and be 100% zero loss. STL on the other hand is normally a mesh. For example if you export to STEP then I import to Fusion I SHOULD be able to change the dimension of a hole and it will resize. I've imported a zillion
