Description: Creatbot DX 3Dprinter stopped extruding. Check if the nozzle is clogged, if the filament got stuck in the feeder guide (Teflon tube), if the stepper motor is working or not and also check the connections of the printer. They were all fine but still the printer wasn't extruding.

Action:  In the above case the stepper driver of the printer got completely burnt out. Printer is used for ABS printing and is having all metal hot end. Due to the continuous long prints, the printer is taking in high power flow through stepper drivers and that led to excessive heating of the stepper drivers and eventual burning out. The stepper drivers have to be replaced.
