  1. @neotko I am very appreciative. This is a much more useful reference for the atomic method with info that applies more readily to my situation. Thank you! I'm off now to pull to see if that improves things.
  2. @neotke - I did not do Atomic pulls (https://ultimaker.com/en/support/view/149-atomic-method) when I moved from PLA to ABS, so thanks for the guidance. The atomic method info says to heat the nozzle to 260, but that would burn PLA, so if I was moving from PLA to ABS, should I have cleaned it by using PLA still for the atomic pulls even at this high temperature? And, now that I have already screwed thing up a bit, having run ABS and had problems, I am assuming that I should go in and clean with ABS (not PLA), is this accurate? Appreciatively, - S
  3. Thank you all so much! It looks like the problem isn't in the feeder, given your guidance. Here is what is happening: When using ABS, when we stop a print (pause OR finish one print and move on to another with cooling in between OR finish one item on the print bed and move to another item on the print bed without cooling in between), the nozzle clogs when printing the next item or resuming printing. Sometimes it is a total clog (no filament extruding), sometimes a partial clog (a bit of filament sort of extruding willy nilly usually sideways). Going through the filament replacement process solves the problem (sometimes supplemented by cleaning off the nozzle if it was a total mess). However, when it prints again, the first few minutes will print yellow (burnt). Even when you replace with the exact same filament that was in there before, and the filament is white going in, it still extrudes burnt for a bit. And the area right above the print nozzle also smokes a bit during printing, so I'm guessing it has something to do with heat. Question 1: Any suggestions? Question 2: We had hoped to move between filaments (part of the reason for purchasing the Ultimaker). You seem pretty adamant that I shouldn't move back from ABS to PLA, at least not with the same nozzle. Why? What are you anticipating/suggesting? Note that we have access to a MakerBot, so can print PLA elsewhere if needed, but one of the reasons for getting the Ultimaker was to have ABS and HIPS as an option. Thanks
  4. Hello Ultimaker Experts, We're trying to fine-tune our new Ultimaker 2 and have a question (or 10). First up: Should the feeder be putting little nicks in the filament? It isn't grinding major divots, but is texturizing it for the full length. I read up on filament grinding and can't figure out if this denting is normal. The visual troubleshooting guide http://support.3dverkstan.se/article/23-a-visual-ultimaker-troubleshooting-guide#grinding identifies the major divots as a problem, but isn't clear as to whether we should be expecting the small ongoing pattern, similar to what it shows before getting to the major divot. We're having some difficulties printing, particularly with ABS, and so I'm working my way through possible problems/solutions. Thanks for any and all help! -S
