I’m having some strange issues. First, here are some quick specs on my setup:
300W DC spindle (included with kit)
~3/4" Plywood (straight from Home Depot)
1/8" flat 2-flute end mill
The problem is obvious from the picture. Basically, about halfway into the full depth on my cut, the bit starts “drifting” slightly. You can see how “slanted” this makes one side.
I’ve attached some pictures of my z-axis alignment as well. It’s not perfect. You can see a sliver of light in both directions, but not nearly enough to cause this (I don’t think).
Belts and v-wheels are solid. The machine moves just fine. I did have to adjust the current on all three axis (particularly the y-axis) to get the movement dialed in. I haven’t adjusted the software at all since (possible issue?).
Let me know what you guys think.
