Hotend does not heat and motor don't move Hello, I tried my extruder, heatbed and motors and all was ok, i was able to extrude filament with repetier manual command. So i tried a print and then it was apocalypse, my hotend stopped sudenly to warm and now it can't warm again and NO motors move. I tested voltage of power supply and stepper driver and they were all ok. I checked thermistor and they works, also endstop works because they led are on when i click The heatbed still works. Please some one can help me ?

i finally found the solution, it was caused by the fuse of the ramps (the yellow things).
My room temperature was at 29°C and so the fuse had got a very high resistance so nothing worked.
The polyfuse of my ramps must have a manufacture default, so i will change the ramps.

Why not just replace the Polyfuse with an automotive type blade fuse and holder?]]> dougal1957 RAMPS Electronics Wed, 01 Jul 2015 13:27:01 -0400 https://reprap.org/forum/read.php?219,527583,527997#msg-527997 Re: Hotend does not heat and motor don't move https://reprap.org/forum/read.php?219,527583,527997#msg-527997 fuse of the ramps (the yellow things).
