I’ve recently ran out of red and decided to buy the Creality Hyperspeed. The project is a simply 6 layer tag with three colors. The other two colors is two different brands. The problem is that everytime it switches to red, it under extrudes. I put the filament in another slot, same result. Swapped to another High speed filament in the slot without telling the printer. Perfect print.
I know it is not the AMS or extruder, as other filaments prints perfect. I rebuilt the hotend with new nozzle, and things improved until the first filament swa. I did the calibrations in Orca slicer,and it prints perfect. My issue looks heat creep, but only for this filament! I slowed down, increased cooling etc. with no real improvement. When I start a print with the filament, it prints perfect, but at layer two it just won’t extrude properly. The next color however prints as good as always.
I have now lowered the temperature to hopefully reduce heat creep and the printer just notified me that the retraction failed… )-: Any thoughts how I can sort this? (I’ve increased purge volumes in case the hyperspeed don’t like the other filament.)
