Hi there peeps!
I recently built a LR2 and was very excited to start using it. Up until now I’ve only done some simple tests in mdf and a few 2d cuts in plywood. All of that went pretty smooth. I learned a not already doing that.
The newest project I’m trying to make is some type of cookie cutter plank. Here in Belgium we have ‘Sinterklaas’ instead of Santa and the speculoos cookies are traditionally made with wooden stencils.
We designed a ‘sexy sinterklaas’ and started cutting in some padouk that I hadn’t used before. Cuts looked good, but at some point a shift was happening in X. I’m not sure when exactly.
Since then I’ve tried 3 different ways of doing it:
First attempt: 1/8" flat endmill, 6mm doc and 8mm/s feedrate
Second attempt: 1/8" flat endmill, 3mm doc and 8mm/s feedrate
Third attempt: 1/8" flat endmill, 3mm doc and 5mm/s feedrate.
I’m using fusion 360. Tested the file first in some mdf to be sure that fusion worked the way I expected it to and everything looked fine, so I’m pretty sure it’s not an issue with the gcode.
It’s only skipping steps in the x direction, which is the short side of my design in the pictures.
I also think the shift happened twice on the last attempt.
The stepper is getting hot, but not so hot that I think it would be a problem.
This is a big issue for toolchanges, too, because the origin moves. (I’ve broken two 1mm bits already :’( )
If you need any more info to help me debug the issue, I’d be glad to provide the gcode, fusion file… Anything. I just want my machine to work as expected.
Thanks already for any insights and help!
