I have built a custom frame from a 5050 extrusion channels and was going to use my nema 17 motors but decided due to the weight of it all to up to nema 23. After doing some digging, I found the my nema 23's are 3.08VDC motors. Checking the output using a volt meter, I am seeing 24VDC. Is there a way to configure the BlackBox X32 to provide 3.08 VDC to the motors?
Modern stepper drivers, including those in the blackbox X32, "chop" the voltage in order to control the current. We can give a better opinion of your motors if you provide the full spec (inductance matters too) but the output voltage from the blackbox, measured with a voltmeter as you did, is fine for 3 Volt motors. Some people (not with the blackbox) supply their stepper drivers with 48 Volts with their 3 Volt steppers, so you definitely won't have problems. Alex.
All the way down docs:blackbox-x32:currentadjustment [OpenBuilds Documentation] for our NEMA17s. Voltage is automatic, but you have to set the Current

I'm getting the red ! on the pots after setting them to halfway and resetting. I even went as far as factory resetting and erasing the eeprom and making the changes below. Am I missing something?

Thats where that came in. Its a suggestion but please Tune it. If it overheats turn it down! See the DOCS it describes the Fault LED too lower down docs:blackbox-x32:currentadjustment [OpenBuilds Documentation]
