Creality K1 Max Curves Surface Issue - eviltoast

I have a K1 Max and mostly it is running great, however I get strange artifacts on mostly only the front side of curved objects.

I have lubed all the rods, and I have a Capricorn PTFE tube from the filament sensor to the hot end. I tried the printable guide for the tube to go into the hot end but it wasn’t any better and I thought that was the culprit at first.

I have an extension piece to raise up the top glass.

I’m using Elegoo Rapid PTEG running at 240c and 250mm outerwall speed. This is mainly happening on the front side and anywhere on the build plate. Filament is dry and fed out of the Creality Space dryer.

These items are small netcups but it was also happening on the larger sections that they go in.

Using Orcaslicer and Arachne wall generator.

Any ideas where I need to be focusing my attention on?

      The K1 series has graphite bushings on the X axis which should be self lubricating and should not be greased.

      I re-lubed the rods before starting another set and still having the issue. I was thinking it had something to do with the Bowden tube but even at the back where the tube doesn’t move much the issue still happens.

      Is there a specific lube that is better than others?
