Well as able to find a board on ebay for $60. But while i was cleaning up my work area, i happened to look at one of thr extra hear cartridges i had ordered… hard to see , but lazer engraved on it 12v 30w… sigh…the ad was clearly for 24v. I dont think this is my problem as it should not effect the readings i was getting from the thermistor. I tested both thermistor as well the bed and nozzle and both read 115k which is right for the temp my room.
Still scratxhing my head about what actuallg happened . But fingers crossed new board will fix it. Will find out in about 3 weeks
So i think we have probably found the mystery as to what happened !
So what did I learn from this . Always double check products from amazon, even if u know that YOU ordered the correct part. What they sent could be different !
New board is in ! . Everything seems to be working. But the machine is louder then it was before? I did performed a bed level and noticed that the extruder motor was gettting very hot , with out extruding any filament? any thoughts about that?
