I wanted to chim in on this. I was having similar problem with my print. Since the material was coming out fine, I thought my extruder voltage was right.
When I went to measure the extruder voltage.. i was only getting .84v (unit fully powered on). I kicked it up to 1.1'ish and it started doing much better on the print jobs. I then looked at the KB provided by solidoodle: http://support.solidoodle.com/hc/en-us/ … Adjustment
Since Solidodle recommended 1.5, I figure I would up it to 1.5. Well.. guess what. My max voltage is only 1.24. I actually measured the voltage on the positive leg and it is 1.24. There is no way I can get 1.5v on the variable leg.
All my other trimpots also had a positive leg of 1.24 and I made sure all the variable legs were set to 1.0v. Sorry if I am not using the right "electronic" terms.
I just opened a support ticket with Solidoodle to see what they recommend.
