The Taz 6 is my first 3D printer and so far it has been a blast. I processed 8 successful prints (benchy, test geometry, a deer of all things) and have had no issues…until I lifted my last print off to find this: http://imgur.com/jaOTUdf
It seems like somehow for a portion of the print the nozzle was too low and lightly etched the build surface…it is only for this corner and the rest of the square print seemed fine. It doesn’t seem too deep, but I can feel it if I run my nail over it. I watched the print start and it seemed to level and lay down the perimeter fine…
So, as a rookie to all of this I was looking for some assistance:
A. Could this have damaged my build plate and nozzle in some way? Initial reading makes me think I have just scratched the PEI layer, but I am not sure how exactly to tell.
B. Any ideas on what could have caused this? My Taz 6 was one of the early serial numbers that needed the frame to be re-squared…I followed the directions in the service bulletin and have had no grinding or binding that I can tell…The print seemed to auto-level fine after wiping the nozzle.
Thanks for any assistance.
