Carbide Copper and Drill Holes Wonky

[RyanLM (Ryan Masanz)]

Trying something new and I really do not understand what is going on. I have Fusion 360 and Eagle, both of the cam processors give me the same results.

I can load the copper files just fine. When I load the drill holes, well, it just isn’t placing them correctly. See the attached images.

Blue is Fusion 360, Copper is well, Carbide Copper. I get that things get flipped depending on if I use top or bottom, but it isn’t just flipped. Part of the holes line up, but part are flipped and kind of inverted? Hopefully you can see what I mean by the pics.

Any ideas? I have been playing with this for hours now and same results each time.

Update I did just find the CAM file that carbide made for Copper, but using that I get no holes instead of holes being somewhat inverted and flipped.

Update 2 Going back to stock Fusion CAM Export, when I export as imperial, I thought it wasn’t doing much, but it was making super tiny holes. (last 2 pics) They are however the correct pattern, just, well, the size of a pin. So, scaling then?

Well after playing with this, I did figure part of this out.

The decimal places were off in the CAM export. It was set to 3, setting it to 4 solved the scaling issue, though the placement on the file was off but I was able to adjust that.

Have you tried another cam program? I use FlatCAM. Definitely need to read the instructions, but results are great.

I have not, I think I did get this to work late last night, but FlatCAM looks more robust for sure. Does it export solid gcode for the Shapeoko?

@RyanLM

Does it export solid gcode for the Shapeoko?

Yes…

If you’ve got an odd offset it could be this setting:

Depends where your origin is.
