Hello,


I understand this is probably a software issue. I'm a very novice user so I'm hoping for some tips. I've had an issue of blobbing and "zits" on my prints with ABS. I thought it was an issue of retraction. I've played with the setting from 1mm to 1.5mm retraction but here's where it got weird. I printed 3 copies of the same small item. About 30mm tall and maybe 18 wide. I only have this problem on the middle one though.


Maybe this is an issue of the retraction kicking in on the other 2 models based on a certain setting. I've tried this in cura, makerware, and Simplify3d. Same issue in all of them with varying retraction settings.


Qidi Tech 1 dual extruder
ABS 235
Bed 115
Print speeds 50-80mm/s (with slowdown on initial layers etc.)




Any ideas?

I can't seem to get the photo attachment, upload, or insert to work. Tried on mobile and PC. Maybe because I just registered? I will edit this post or add it in another post shortly when I am able to upload photos
