Can one "stepper motor drive control" power two stepper motors?
I have one TB6600 Stepper Motor Drive Control I want to use with two stepper motors that will move in sync. If I connect one motor to it it runs fine, if I connect a second one at the same time (to the same connections on the controller [A-,A+,B-,B+]) the motors try to move but just buzz. I thought it would be because each requires 1.68 of current, so I set the dip switches to current of 4.0 or 3.0 Still just buzzes.
Can this not be done or do I need a complete separate stepper motor drive control? I am driving the motors with 12V. The specs on the motors say 1.68A, step angle 1.8
I have looked into that since I posted this question but it seems like the speed of the two stepper motors will be much slower, have not tested it yet.

if they are getting the correct current and the correct step frequency why would they be slower?
You may benefit from a higher voltage power supply - within the limits of the driver.

yes is it. in your stepper motor does have 12V with 1.68current, if you want to turn on 2 stepper motor together with 2 TB6600 driver, you need to use external powersupply with up to 4A current.
The power supply I am using is DC 12V 30A 360W . I did run a test last night hooking both stepper motors in series and they both do run, but slower and struggle a bit.

If they are wired in series, as they should be, the current will still be 1.68 amps.
If you wire them in parallel and set the driver current to 3.36 amps you can't be sure that the full 3.36 amps won't go through one motor - until the smoke escapes.
