Hi,
The only difference is the load, it works fine if it has nothing to move and fails when the motor is plugged into the belt and has to move the extruder. That's the reason I'm thinking the problem is probably a low torque. Still sounds weird to me though, as this motor and driver models have been used for a long time in prusa printers as far as I know.
If I try moving the extruder by hand I can tell that it moves smoothly and the element that offers the more resistance is the very same motor that is not working fine. Is the first time I play with one of these so I can't really tell if the movement is smooth enough.
One thing that I haven't tried is to put some oil in the rods but, as I said, I don't think it will make such a difference because it feels like the motor itself is the one element making it harder to move.
If you can think of any other test to know where the problem is I'll be glad to try it.
Thanks for your help.
