I’m sure there is a perfectly simple explanation for this, but I need some assistance to see it. I purchased a delta printer a few months ago and have worked on it off and on with no success so far in printing. The issue I have now is that when a print begins, the filament will not stick to the build plate. Rather, it pulls up, with the nozzle essentially kneading the filament like dough (see the attached photo). I have tried increasing and decreasing the Z height with no effect.
After great success with the Makerbot Replicator at work, I thought I would give myself a challenge. Clearly I was not ready for some of the intricacies of kit printing. Any help you can give would be greatly appreciated.
