Extruder Heater Not Heating
I've started to do my MK2.5 upgrade, but before that, I decided to change the nozzle, but in holding it, I think I shorted out the heat cartridge on the extruder and from there, it stopped heating. I figured when I took it all apart for the MK2.5 upgrade, I'd replace the fuse, but I checked all three fuses and they seem O.K. What else might it be?
Re: Extruder Heater Not Heating
Hi Allen, does the LCD Show the normal information?
if blank the power supply could be duff... I believe there is a fuse inside the power supply, another in the IEC Power input socket and often in the plug too
if the display looks normal
could be a faulty Rambo, (output FET blown)
or faulty wire,
or faulty heater
or faulty connector

Re: Extruder Heater Not Heating
Thanks. No display seems normal and everything else normal, but did receive the "extruder not heating error." I was afraid it might be the board. Maybe a case where the $120 board blows to protect the $ 0.05 fuse? Ordered another board in case that is the problem. Maybe I'll look at the board more when I take it out for the MK2.5 upgrade.
Thanks again.
