Anyone got any ideas on this?

Seems to me like bad/wet filament

Yeah its probably wet like he said, you may also have a bit of over extrusion leaving the blobs

also this might be a good read for you to experiment with

Just calibrated on estep, there might be a bit under extrusion but not over. This might indeed be a wet filament issue, I’ll dry my filament in the oven and see what happens.

even with perfect esteps you can still be over extruding tho. check out this thing about slicer flow calibration:

[Teaching Tech 3D Printer Calibration (teachingtechyt.github.io)](https://teachingtechyt.github.io/calibration.html#flow)

most my filaments run best at about 91% flow rate.

but yeah its likely more related to the filament itself
