Hi!
I started repraping not so long ago and I already run into troubles: After I plug power to Melzi board extruder heater starts heating. Temperature sensor works ok - I can see proper reading in Proterface. I measure output for extruder and it's 12V constantly, no metter if termerature reached it's target set in Proterface. It's 12V even if don't turn on extructer heating. Everything except that works perfectly.
What could be the problem for such behaviour? Is it possible to fix it or I should get ready for new control board?
PS. I don't know much about electrnics.
Thanks for any suggestions!
Artur
