Hi all,

sorry for the late reply...

I don't know where you buy such low quality filament, that you have to dry it bevore printing...
My filament comes in a vacuum sealed package.
I use 8 different colors of PETG filament with my printer, unpacked since 1-8 months and there is no quality difference.

I use a retract of max. 0,25-0,5mm.printer.jpg

Also see my youtube video, printing at ~390mm/sec.
