Hi, So I just got the stepper kit in and hooked it up to my teensy. Im running a test script and no motion on the motor. I then took a shot in the dark and hooked up the driver to a normal old arduino uno and walla motion. Am I missing something?? How are you getting the teensy to drive the motors with just 3v logic?
The Stepperonline drivers (DM542T and the 320) do operate at 3.3v they are supposed to be updating the manual to show that. I assume you are running DM542T drivers. Are you running the AR4 teensy sketch on the teensy 4.1?
@chris-annin Im playing with custom software ( Accel Stepper Firmata ) so not running AR4 software at the moment. The only difference between my wiring and yours is im using the +pos pulse and direction pins. I am using a Teensy 4.1 and strangley everything works fine with an old driver I had kicking around in my shop. But with the new drivers that came in the kit it only seems to work with an arduino
I figured it out!!!! So turns out after reading through this https://forum.pjrc.com/threads/48524-Stepper-Driver-Voltage That you need to increase the pulse width in accel stepper and walla!
@joseph-puzzo I think you'll need to run the AR4 sketch with -neg pulse. Keep me posted if you have any issues.
@chris-annin Issue resolved. that pulse width setting in the accel stepper was all I needed. Looking forward to getting this thing built!
