Hi guys,
So I bought a Chinese 3 axis 1317oz kit with 80v / 8.2 amp stepper drives.
Problem is, I bought this knowing the motors had lousy torque curves and the power supply was underated, but wait a minute. There are 3 supposedly amazing stepper drives rated at 8.2 amps and 80 volts with a 200khz pulse rating and heat sinks.
So I'd forgo the rubbish to get my treats!
Well, these units are only rated to 5.8 amps, and never were offered as 8.2
The wires into the steppers are 1mm core (tiny for a 1317oz rated motor) and the motor exhibits no magnetic resistance when spun by finger. (I guessing the magnets came of a fridge)
My wallet feels a lot lighter and somewhere in China a shrewd little (censored) is counting my crisp dollar bills.
BEWARE!
