Dual motor with eternal drivers
-
Good morning the best community ever!!!
I have a question about the power of pulse's for external drivers.I'm working with 2 steppers and I want to use same wearing from board (step/dir/e/p) to 2*external drivers. I want to control both with the same signal and I need to keep the max power for both.
I know that each external drivers have own power needed for each motor. But the signal from board, could have less voltage if I divide it ? So maybe I will have issue with loused steps?
If not, so I can connect infinite motors (with external drivers each one) for same axis without problems?
Very grateful for your communication.
Thanks

@xXJRUSHMANXx When using external drivers, you only drive logically, no need to worry about current issues, I mean if they are set right in the external driver. Still, cant use quite an infinite number, as wiring capacitance will increase, and also current drawn by optocouplers (inputs) will increase too, but for a no of external drivers, it will do. Beyond that, use buffers. Beyond that too, get a ZPE.

@soare0 Nice, a Stargate reference!

@droftarts It is just normal, as our first planetary SG will be printed with a Duet powered printer... somewhere in the future.
