Noticed StepperOnline’s 17HE19-2004S specs say 55Ncm(77.88oz.in) torque:
Note some potential fun to be had while wiring 17HE19-2004S :
Best selling amzn (US) steppers seems to be prewired higher torque capable Stepperonline 59Ncm(84oz.in). Which are more expensive than V1E’s 84oz Nema 17’s (ignoring delivery cost). Hopefully most Makers are using these or some other prewired Nema 17 steppers.
Maybe use prewired 84oz for the Z steppers, if not everywhere.
