I am having a very odd issue that I can not account for even a little.
Every time I try to print in PeTG the material gobs up, then gets stuck on the nozzle.
Plate is clean. Nozzles and PTFE tubes are clean. Plate is leveled perfectly as per a feeler gauge.

Trying to print a set of a velocity stacks for a buddy, have done 3 of em so far and they came out perfect. This 4th one will not start. Always gobs of material by the 2nd or 3rd layer. No settings were changed in S3D or the machine.
I just cant figure it out.
