I'm trying to use an external step driver (DM556), because I've got nema23 5.6A. But I'm not sure how to set up the wiring on TinyBee board.

So far I've tried some combinations that I've found for others similar boards, this set up did not work:

Neither this one:

Or this

Can anyone help me out?

Really appreciate, thank you!!!

Hello. Your driver must first be configured for logic high/low control signal levels. The connection shown in your picture №2 appears to be correct and should work if the control signals are of the correct polarity. In this instruction https://cnc-tehnologi.ru/files/DM556.pdf has a typical connection diagram for your driver. TinyBee has special connectors (4 pcs.) for connecting external stepper motor drivers
