The Everything 3D Printer Thread

The color/sheen change could be from the layers having more opportunity to cool as the printer goes between both parts on the plate. Once the shorter part is done printing, the layers on the taller part will print faster, with less cooling between layers. That looks like a transparent PETG, which will often have different finish appearance based on speed, layer temperatures, layer height, etc.

It is transparent purple petg, looks nice when done properly. I did reduce the purge volume, i’ll put it back to 1. What test prints should i consider running?

You will likely need to increase the value in the table above that too (I know it doesn't look editable but click on it.) Even if it's just a little too low while you might not get a split your print will be extremely weak at that layer boundary. PETG just really doesn't want to stick to any amount of PLA.
