Topic: Lumps & Bumps When Extruder Head Is Moving Away From Base (See Pic)

For some reason my PLA is lumping up and bubbling when the head is moving away from the base. Otherwise, nearly perfect prints. But it seems that no matter what I adjust, nothing fixes it. I've literally been on this issue for 8 hours, and I'm hoping someone here will know the answer.

Thanks everyone...

At first look, I would say to adjust the first layer height or you are over extruding a bit. And if printing PLA, add a fan to the hotend. PLA takes longer to cool than ABS.
Calibrate your extruder, adjust your E VREF, and then run a couple tests. If it still does not perform properly, or you have already done it all, check your extrusion multiplier....it may need to be lower.

Could you mention what you have adjusted or added? What model Solidoodle are you using?
