I’m not sure if this is a software or a hardware issue … but I’m leaning more towards hardware. First of all, my printer is an ao-101 with an upgraded budaschnozzle 2.0 with a 0.35mm tip. I’m printing with PLA from filaments.ca
Since about a week, the surface of my parts is really rough with many imperfections. At the beginning, I thought it was a fan problem and found that my fan was working 100% all the time, so that didn’t help. This is fixed.
Yesterday, I successfully printed a part and was so happy because I thought I finally found the right slic3r paramaters. So I printed the part again right after the first one, and got again a very bad surface and even some cracking.
Parts in pic 1 and 2 were printed at 0.28mm, with automatic fan settings @ 200C and 60C bed, EXACT SAME GCODE
The following was printed at 185C, 60C bed, 0.22mm layer height
My last print, it’s getting worse…: 200C, 60C bed, 0.22mm layer height, automatic fan setting
I regularly measure my filament diamater. I tried increasing nozzle temp. I played with speed, infill … pretty much every slic3r parameter. I tried to tighten every possible bolts on the printer. From the pictures above, does anybody recognize a possible hardware problem ?
By the way, I start from lulzbot PLA medium profile and try changing one parameter a the time, but nothing seems to really help.
I’m willing to try things to solve the problem …
