Hi guys, it's been over a year now since I wired up a stepper and over the last few nights I've been pulling my hair out.
I've wired my stepper up, 4 wire, and my controller turns it nicely, but even when I hold it by hand it just judders and stops...never mind putting any cutting strains on it! I'm using one of kwackers divider controllers to run it although the motor is actually turning a linear table axis. It has worked in the past but I'm sure it is wired correctly and I'm sure the divider setup is correct! Likewise, if my wiring was wrong, would it still turn smoothly with no load?
Could the stepper have died? - only I'd have presumed it would have totally blown if this was the case but as it is, I get perfect smooth motion when under no load. Yet virtually no torque both driving or holding.
Any thoughts, help or advice appreciated.
