I made a few changes:
- I tried without the arc G-codes (G2 and G3), it took some time to figure out how to get fusion 360 to “linearize” the output.
- I removed the vacuum holder
- I also tried with 400mm/min (6mm/s). It burns the wood much less.
- I used a 3.125mm one flute end mill ebay link. I do not know if it is any good?
The result is not too good. See attached.
I still need to try something softer then plywood.
I do suspect that maybe the x-axis to be too long, and maybe the aluminum tubes I have used are too flexible…
Again, thanks for the suggestions.
