Hi,
best guess is they are 23 size steppers, you say they are 100 mm long then my guess is that they are 4.2A units 250 N.cm rated. That works out to
325 oz.in, plenty good. The drives are capable of up to 50V. Do you have a multimeter? Can you measure the power supply voltage or can you
see some specs written on it. For best speed you want it as high as you can go, if its 24V or less then its a joke and should be swapped with one with
36V or better 48V. Best to allow for full current for all motors simultaneously so rated current ideally 12.6A or better.
You should change the current switches so that the current is closer to rated.
SW1 ON
SW2 OFF
SW3 OFF
Should result in current of 4.2A. In practice the steppers may get too hot and you'll have to consider backing the current off. Dropping it to 1.5A is
too extreme.
The full/half current switch refers to the idle current, it can be left as is.
