Need Help Setting up: Sherline Mill + XS-3525/8S-4 + Mystery Stepper

Update: I found the specs for the motors [thanks Wayback machine!]. I guess these were sold with Xylotex controller as a package at one point.


Other than being slow, they seem to work ok.

Supply voltage is running at 23V. I've not measure the current yet. (need to use a scope for that.)

For the standard sherline supplied steppers and drive, the MaxVel setting provided by them is 0.4 if you want another point of comparison.

No issues with stalling on x and y at max jog speed and with feed rates of 4~6in/min can do .020" cuts in mild steel with a 3/8 endmill OK (no powerhouse by any stretch though!) Z needs more power for drilling though. That one does stall more often than I'd like!

Check that the gibs are properly adjusted, if they are too tight = too much friction, but too loose = too much slop, especially noticeable on Z when drilling.
