So from Pronterface I get good readings from the thermsistor it shows 25C. I turn the extruder on and the red led for the extruder comes on the ramps board. I can read 5v on the gate leg of the mosfet but read no voltage on the Drain or source legs. I have 12v on both the inputs for the ramps. I read 12v through both of the fuses. The heat bed d8 is fucntioning properly. I thought it was a bad mosfet but if that was the case shouldnt I be able to read 12v on the source leg?
I'm stuck so any thoughts are suggestions appreciated.
I purchased the ramps areleady built and it fuctions properly (i.e motors endstops thermsisters and heat bed) except for D9 and d10.
Help please!!!!
