    Will this .72 stepper play with TinyG/tgFX or is it strictly 1.8?

    NEMA: 11
    COIL: .75A/1.2 ohm Pentagon
    TYPE: 5 Phase Bi-Polar 5 lead
    STEP ANGLE: .72deg/Step
    USED VEXTA Pentagon drive Motor, 5mm dia. X 14mm steel shaft with 8mm slot. 4 corner m2.5×2.5mm mounting holes. SHORT 1/2″ wire leads
    L: 1-1/4″ (Body) SQ: 1-1/16” WT: .06

    I don’t think that motor will work. It’s not the step angle that’s the problem, it’s the 5 leads. The stepper drivers on tinyG (and almost all stepper drivers, actually) are bipolar devices consisting of 2 independent drive circuits. These work with 4 wire, 6 wire and 8 wire motors. Odd numbers implies common grounds between the phases, which require special drivers.

    I think I may have been interested in that motor as well. I saw it on MPJA. Until I saw the 5 lead config and moved on.
