As I get closer to being able to try power tapping I'm wondering if this sort of tap is suitable? https://www.amazon.ca/gp/product/B00F8T55GC/ref=ox_sc_act_title_3 Or is it garbage that will break in aluminium castings or mild steel on the first try? I'm at the point with encoder feedback that the spindle is at the desired speed and with setp spindle-near-speed.difference 0.1 and some PID tuning it's up to speed pretty quickly and seems reasonably stable. Running a simple dry run tapping test it appears to behave. I'm tempted to try it in a piece of soft wood. g20 g64 g90 (Speed and feedrate ) s100 m3 F5 (Tapping) G0 X1 Y1 z1 G0 Z0.1 G33.1 Z-0.5 K0.05 G0 Z1 G0 X1.25 Y1.25 M5 M2 % "ELS!
