I preheated the nozzle using the "preheat ABS" setting via the ulticontroller before printing and also tried setting the temp to 250C under the "control" tab on ulticontroller and with both methods the hotend heated up to 250C, but the extruder motor still didn't turn on.
I have UMO selected in cura. I usually preheat before I start my prints via an SD card and havent had an issue with the motor until this week.
How do I check and see if it commanded to 0C?

Extruder won't turn until temp is over 170C but I believe preheat only heats to around 170C, right? So just manually set the temperature using the ulticontroller to the temp you want to print at and then start the print. You might want to check the temp to make sure it isn't commanded to 0C or some other wrong temp.
In cura did you select UMO+? For my UMO I always select 0C for the nozzle temp such that I can just set the desired temp on the ulticontroller and start the print when the temp is close enough.
