K2 plus nozzle building up with filament. This is my first creality printer and first time using creality print, but I've been print on other machine with cura for many years. I'm printing with prusa petg v0 and getting the nozzle to build up with lots of filament on every print. I adjusted my z offset to 0.1mm and it still could complete the course flow calibration. Current flow rate is 0.92. Based on what did finished on the flow calibration test the now flow rate should be 0.73.which seems suspicious low. Any help would be appreciated. Also, I'm using creality print 5.1 since 6.0 keeps giving x and y axis run away errors.
