Extruder starts but never stops (commissioning huxley)

Extruder starts but never stops (commissioning huxley)
June 13, 2013 07:40PM
Hi all, i'm new here, I have just built a reprap pro huxley with the meltzi PCB, all other functions are good, but the extruder when set to advance / reverse 5mm using the printer interface (following an M302 command to allow cold extrusion) never stops running.

Is this normal!?
Is there a list of all the G or M codes somewhere so I can see what they are/do!
What is the command to cancel or stop the extruder (other than to (software)disconnect/reconnect?)

The voltage is set to 0.55 on all steppers, thought the extruder is bigger should I set it higher, though it rotates fine at the moment (no filament in it yet) just it never stops - after several minutes!

Had an enjoyable time building it so far, I hope someone has an idea what might be the problem?

These are the default settings on the board:

Just seen a few others with the same issue 4 posts down. I'll have a look through tomorrow, some of the questions might have been answered there....
I am having the same problem: how did you solve it?

Thank you.
Actually I found the solution in the other threads as well: M502 M500 and restart Huxley.
