So, I just got a Precision Matthews PM-970 (RF45 clone) up and running with a Linuxcnc based retrofit with all of the bells and whistles. This is my first project.Also, built a planetary gear polisher, since I don't want to hand-polish 6 sides of 36 dice.Not a single step of this went the way I planned, but I think the work product turned out nicely.I didn't tune the PID properly to begin with, which I think is why my final dims were ~5 thou out of spec in some parts. This cascaded down to needing to remove more material in sanding/polishing. I left the final profile cut to 0.005", but didn't do a spring pass, which I think led to some tool deflection, which caused some tilt in the second op.Anyway, for a first CNC project for a manual machinist. I'm happy.
