Ramps1.4 Problems Motor.. Solved..In Part....

[zumpitu]

Hi All !

I want to report a little frustrating experience I had with my ramps... at some point the stepper motor was not working anymore properly, like they had no enough torque...some noise and little random movement .


So i tried ne stepper driver , recable ecc... no result, but then I accidentally pressed the button reset and.. Yhee ! Now they work again !!

So if you have this kind of problem, just press reset ( on the side of the RAMPS) reconnect and go

But I still have this problem quite a lot, usually happen on the end of a print... Somebody know why this can happen ??

Ciao !

Sounds like an over heating stepper driver. Do you have the heat sinks on and good air flow?

Hi nc42 !

I actually have only the standard little sink, but I use a Nema 23 maybe could be a over heating I will put a fan over to check
