Cyclop extruder temperature problem, Prime Tower infill

[nitroseba 0]

Hi,

This is my first post on this forum so please be forgiven if I write something wrong.

I printing for a while with cyclops hot end and I encounter some problems with Cura software.

1. I use the same temperature for each extruder, I make new PLA profile with same temperature as well. But when I printing before changing filament, printer stops for couple seconds and heating ups. And nozzle melting printed parts.

2. Prime Tower - Is there exist any solution to change infill to lower without changing size of prime tower. When I have only some deatils in diferent color, I waste time and PLA because prime tower can print ony in 100% infill.

I use marlin and Ultimaker Cura 3.0.

I use Prusa I3 clone.

Sorry for my english.

Regards

Sebastian
