I have been using my Smoothie for a while now, and have been suffering from step loss. I have been looking at the stepper wiring and current being used by the stepper.
I have a #23-305-DS8A (425oz-in bipolar rating, 305oz-unipolar rating, 4.2v, 3A, 200 S/R, 3.2mH, Size #23) and some smaller #23-205-DS8A (3V 3A) - they are 8 wire steppers and are wired for serial and have the current set to 2.0 amps (ie all set to alpha_current 2.0)
Is this the optimal setting? Some reading I’ve done would indicate the when wired in serial I should be using Current rating / 1.4 - so X-current set to 1.7
Would their be benefit of configuring my steppers for parallel at setting X_current to 2.0?
I could run some experiments, but I would like to start from a position of basic understanding before messing with my setup.
