Chinese 2.2kW spindle - wow & flutter

No!!! No vacations, only work, it's my slave. 😉 but it's a nice spindle, not gets hot, no strange noises.

Just to close the loop on this - I've just hooked up a RS485 USB adapter to the controlling PC, linked it to the data lines on the VFD... then, like a lot of people, reversed the connections to the data lines, and with the help of the M3 plugin, have digital control of the spindle with NO wow/flutter. Clearly an analogue issue, somewhere between a cheap PSU and cheap BOB, but for now, digital control is the way forwards for me.

Just one update, spindle still running (22h day 6 days weekly) without problems, but the vfd exploded last weekend... I think it's repairable.. Heheh

Hey - four years of hard labor ain't too shabby! Ballpark lifespan of 27,500 hrs.
