Extruder Suddenly Doesn't Run July 03, 2016 03:15AM |

Hi
Strange malfunction. Extruder motor stopped working.
Switched between X axis motor and extruder - Result: extruder works and X axis dosn't.
I figured maybe driver is gone.
Switched between drivers - extruder still doesn't work.
So... motor is ok. driver...probably ok.
Settings? (I didn't touch them. shouldn't be a problem)
Ramps? maybe. I find it a bit hard to believe.
Any more ideas?

It seems that the problem became more complex than I thought.
I couldn't understand why the problem repeated even when I tighten the screw.
I found out the extruder motor became so hot that the small gear (greg wade reloaded) twisted after few minutes.
I found it interesting. I'm trying to print an ABS gear. mine is PLA. Hoping it will solve the problem
Though I reall don't thing the motor should heat so bad...

You've changed the drivers a lot. Did you also adjust the Vref on the drivers? Maybe they get too hot and switch into overtemp protection mode?

I didn't touch the Vref at all.
I don't think the get in overtemp protection as the motor continue to spin (if I understand correctly that overtemp is when the driver shut the motor until it cools).
There's a small fan pointed on the the drivers making it possible to run.
The motors still get very very hot. Impossible to hold by hand.
