Hello, I'm new to forum (and Arduino) so I hope I'm asking this correctly. Does anyone have any advice/guidance for interfacing a UNO to a Leadshine DM556 driver? https://www.oyostepper.de/goods-1248-Leadshine-DM556-Digitaler-Stepper-Treiber-05-56A-20-50VDC-f%C3%BCr-Nema-17-23-24-Schrittmotor.html I'm planning to use a NEMA 34 motor to drive the Z-axis on small mill. No positioning, just want to control speed and direction.

Hi all, I'm having trouble with connection to the teensy 4.1 board. My AR4 has been running fine since building it a few weeks ago, however I now can't seem to connect to the teensy. When trying to diagnose the issue, I've check the Teensy is healthy by unplugging from the robot and running another script on it. all seems fine. (I've also tried replacing the board with another Teensy 4.1 with no luck) I find that the board will boot up when out of the robot and i can connect to serial (but still not in the AR4 software). as soon as its plugged in it seems to disconnect from serial. I'm assuming I may have a short somewhere but don't really have idea of how to move forward and find it. Any advice would be appreciated.

Can someone PLEASE post a few pictures showing how they have their servo motor drivers wired?? I can't get mine to respond to the software commands and have determined the issue to be my servo motor driver wiring. Thanks in advance :)
