Trying to improve print quality with my Custom COREXY machine
Running PETG at 255 degrees, with 70 degree PEI Bed
I have also run at 235 degrees with similar print quality

Extruder is a Bondtech Mini Direct Bowden
Bowden tube is aprox 400mm

E3D V6 Bowden 1.75 with .4mm nozzle

Simplify 3D Settings

.40mm
.89 Extrusion Multipler
5.5mm retraction
-0.1 Extra restart Distance
0 Retraction lift
60mm/sec retraction speed
1mm Coasting
3mm Wipe Distance

.25mm Layers
3 top layers
3 bottom layers
3 Perimiters

30% Fill Honeycomb full
100% infill width

80mm Sec Speed
80% outline speed
80% infill speed

1.71 Filament diameter
Bridging extrusion multipler 90%
Bridging speed multiplier 110%

Perform retract duding wipe movement - enabled
only wipe extruder for outer most perm - enabled
Avoid crossing outline for travel Max allowed = 3mm

Any tips would be appreciated.
