From fusion to gcode and the headache in between

Ive watched this guys video(s) https://www.youtube.com/watch?v=G3h4Oe2i3Xo and I designed a lil coaster similar to his tabletop. Ive exported it as an STL and run it in foam with estlcam. I would like the ability to export the code directly from fusion. I have flyfishers most recent post processor and I have exported code. I think I have some placement origin issues though in the design. I probe home and zero and when I hit play I get an immediate soft limit error.

Ive set this up with the intention to just cut it out of foam (not all the way through) just to kind of get used to it.

The first moves are in negative X and Y.

I know nothing about fusion CAM, but it looks like the lead in is what is happening in negative space. I think after homing, if you jog in positive X and Y a bit, then zero X and Y, and then run it with that as the origin, it will work.

I suppose if you could do this first after homing, then run the gcode. It jogs to where the negative values would be 0,0 instead of negative and sets that as 0,0. You would just have to note that X0.313, Y3.68 is actually 0,0 in machine space which would keep you in bounds.

G1 X0.313 Y3.68
G92 X0 Y0

Again, that’s a workaround because I don’t know Fusion CAM. In Estlcam, I would just change the origin.

Interesting. guess I have something to do today :smiley:
