NEMA 11 stepper motor, one phase down

(1/1)

gaoshenkoiie:
For my dual extruder I use NEMA 11 stepper motors, 0.67 Amp/phase.
These light stepper motors can easy go down when powered with a higher current as specified. Per mistake I fired one up with 1.5 amp and immediately one phase was gone.
When it happens you can conclude this by measuring the resistance from the 2 phases. (see motor spec) Both phases should be close to equal. Mine should be 6 ohm and measured 2.3 and 6 ohm.
Good luck printing

thm_w:
Good to know.
What were you using to control the current, a pot on the stepper driver board or was this with a serial command to set the limit?
What was your supply voltage?

Wonder if its difficult to use a single motor for a dual direct drive extruder.
