Prusa i3 pro b extrusion problem

[robdave32]

Got a prusa i3 pro b but have some issues. Most I can manage but one problem bugging me is the extruder.

When not printing and testing flow it goes great but when printing g starts extruder flow is poor and juddering.

Any ideas.

You can remove the fan on the extruder to check if the extruder motor works normally when printing.

Pretty random after second layer it started feeding great and best 3d print just got to figure some ways to make print not stick like glue just bought blue masking tape going to try that.

Thanks for that, any idea how I would test current with a multimeter from circuit to motor.
