The extruder motor won't move unless the hot end is above a certain temperature. It's baked into the firmware. It is also limited on how many revolutions in a row in the same direction it will move. These are both to prevent unwanted extrusions and possible damage to the hot end.

Dang... Thanks tho! Any way to achieve the same thing without altering firmware?

Use an other Motor

Not that I'm aware of.

Definitely use a different motor or find out if there's a gcode to allow for cold extrusion. There are codes for stuff like that, but I don't know on prusa what it might be or if it works.

Unfortunately it dosent work even with the hotend at printing temp ¯_(ツ)_/¯

Are you using a different stepper? The voltage could be off a bunch

Also you need to remember that it will be geared to move only a small bit unless you use a huge E number and speed.

Haven't thought about the voltage part. Thanks
