The interface keyplate for the E-motor, thermistor, hot end heater and fans? Yup, first thing i checked - i’d actually blown one previously being a jackass replacing a gummed up hotend while it was live, so i had spares (couldn’t get in Australia, had to order from the US so i doubled up )
Also i’m an idiot, the -15 thermistor was bed, not hotend, so i’ll have a look at that tomorrow as it’s most likely cabling (got spares). Still aggravated with the e-motor though. If i run it to load, it kicks in for a second, then stops. Motor runs fine on Z controller though. This was actually the cause of the re-kit - put in a flexion, then decided to toss in a new nema since i was having extrusion issues I couldn’t resolve with calibration and kill two birds with one stone. Got rocking behaviour on the new motor, then stopped, then the old one no longer worked so i thought i’d blown something again (although still not sure how). Went through everything part by part right up to the entire mainboard…which meant i had to reflash as the new board was definitely not the same firmware as the LCD. Been a conga line of aggravations tonight!
