Strange outgrowth in print

Recommended Posts

Posted · Strange outgrowth in print


I had a strange phenomenon in my last print. Has anyone seen such outgrowths as in the photo?


Some background information:

I'm using an Ulitmaker 2 with ollson block and 3d solex race nozzle 0,4 mm

Firmware is Tinkerware 16.01

Sliced with Cura 4.6.1


* It is too meaty for stringing and combing was enabled anyway

* Maybe partial clogging that releases from time to time?

* Maybe the STL file was too detailed and the firmware can't handle the gcode and did some erraneous movements? (gcode appended)

* I have a postprocessing script running that displays current layer and remaining time on the screen. Maybe that introduces errors into the gcode?

* Any other ideas?


Would be great to hear from you!
