I have assembled a RepRap from RS Comonents and everything seems ok, except when I start a test print, just a little PLA comes out of the extruder nozzle, then it stops.
The head temp is 200C and stays there within a few degrees.
If I run a manual test, by lifting the head out of the way of the bed, the extruder pumps PLA out in a fine stream which looks ok to me.
Is there perhaps a code in the gcode file that is changing the flow rate ?
What is the correct temp for PLA and what is the correct feed rate of the material ?
Any ideas what is happening
Thanks
Mike
