Gav, i dont blame ya mate!! im sure i've caused lots of pain on this one!!. it has taught me patience which i guess is a good thing.
I just soldered the wire as per Daniels post and adjusted previously so it looks like the positioning of Nino's stepper and still no luck... The wife just shook her head when i went outside to do the soldering and test again. I think she is looking at the Pro Football with "lets take it to the tip" eyes
Sigh
Been there done that X100..
Everyone started from somewhere - bit of a baptism of fire, but I see this as a challenge, not a problem.
Stepper is readjusted - no difference.
Now lets take a step back and recap. What are the outstanding issues ?
A five second check - Have you cleaned the connectors between the head and the body ? You can use a wire brush or 180 Grit on the male connector.
