I have printed everything but 5 parts (feet, 1 x XY, tool mount, “M” top corner, and the nut lock). I have probably tried printing both the M top corner and the tool mount a dozen times with different retraction settings, heat for the bed, nozzle, etc and can’t get rid of the small groups of bad layers. I’ve attached a few pics to show whats going on. Here are my settings.
Nozzle size .5
Layer height - .3
Perm, top, bottom layers - 3
Speed 35mm / sec (I’ve tried 20-50 as well with similar results
Retraction distance - 3mm
Extruder Temp - 200 (tried 190-210 but this filament works great at 200)
Bed Temp - 60
I do print with a brim for the tool mount (2 layers and 10 perimeters)
All of my other parts have printed perfectly without any issues but these 2 have consistently failed.
I’m so close I can taste it.
