S3D support and Craftunique are unable to isolate despite much problem solving.
PROBLEM:
Random and slightly diagonal lines/streaks across my PLA prints.
1.5yr old Craftbot3 (CoreXY design) with moderate usage.
Problem only started recently.
Started on head1 then eventually started on head2.
Layers are about 1-2seconds long
SOLUTIONS TRIED:
Rails - lubricated
Material - swapped with fresh reel
Speed - various
Extrusion - layers all look uniform and accurately laid, only colouring seems affected
Temp - not enough time for temperature to fluctuate so consistently within or between layers
Something loose - layers all look uniform and accurately laid
Stl file or slicer - printed previously without issue
It is only a problem with these parts, because they form part of a desklamp and have light shining through them.
Thanks
