Because the X scale was way high, nearly 70,000, I ordered a longer belt and put a bigger pulley on the motor, getting me down to the mid 40 thousands for an inch, and it was big enough I could get a hold of it and force it off zero, but I was not able to force a fault with a 15 or 20 degree turn, all I could muster. Positioning it against a chuck jaw and jogging into it succeeded it turning the locked down BXA tool post a few degrees but not in tripping it off. Stubborn thing. With the bigger pulley, I expect I could set the maxvel up to over 100 ipm. However, I'd also say a 1nm motor is a great plenty for x on a lathe this size, an 11x56, 2nm is certifyably overkill. Now when I got both eyes open, to see if I can make the hal file do as I want. Apparently I'm walking on new ground.
