Hi guys, been trying to figure out what is going on with my printer, during only the first layer in having these popping sounds and what looks like overextrusion. Im printing on glass that is almost perfectly leveled with a BLTouch so that compensates even more. This only happens on the first layer and the rest is fine. I have tried;
Ajusting Z offset for different squishes
drying my filament in the oven
every axis belt is tight, no wobble.
Any ideas? It almost looks like pressure is being built up from overextrusion but im not entirely sure. it only happens in certain straight line runs, and tohers look perfectly fine.
