Print quality of greay Hyper PLA

Hi, I’m new to this forum and need some help.

I’ve been printing a large project passing about 30Kg white and gray Hyper-PLA (Creality) over the past three months on a K1 MAX, without issues.

I did upgrade the hot-end with a Microswiss unit after about 10Kg.

Recently, I ordered another 6KG grey Creality Hyper PLA and got the worst results ever. This while using the same software and slicing settings.

I had the same results from two separate rolls in the batch.

Then I ordered another 4KG of gray from a different batch that gave the same results.

PS. White Hyper PLA prints 100 percent.

I replaced the spindle holder as it had some groves and could interfere with feeding filament.

Replaced the PTFE tube

Removed and cleaned the extruder

Installed a new nozzle (0.4mm)

Updated software

Using Creality Hyper PLA “Standard” (default) configuration, I ran the calibration temperature and flowrate.

What else can I do or check to help resolve this issue?
