Hi everyone, I am having an issue with extrusion on my S5. Currently have AA 0.4 with PLA and BB 0.4 PVA. I either have the issue that the material is practically spilling out from one print core when the other head is printing. Also, then when the head switches it to print it gets rid of the blob on the nozzle and then there is virtually no extrusion (some small dots now and again but barely anything). Any suggestions?
