Inconsistent first layer

[Blackboard14 0]

Hey All!

I'm having trouble with my Ultimaker 2 Extended printer (no mods) and I'm hoping someone can lend me a hand! I'm printing two large surface area objects next to one another and I can't get the first layer to stick right in all places. I swear I leveled the bed properly, as the perimeter lines print fine; but once it gets to the interior fill, it starts to ball up in random places. I have included a picture. Thank you so much for your help!

I think your head axis are messed up... It happens when for example you make some atomic method and your head isn't in a corner.

When you push/pull on your head, you just make a big pressure on the axis and then when you print it's messy because they're not totally straight anymore.

Try to get them out and check if they look to be bent, otherwise check your calibration and your bluetape position again first
