Also I can see on this silver print that it leaves a slight gap between lines when doing the flat base.

Hi, For some time, my printer skips every now and then while printing. Is this normal? I've been trying my best on cleaning the nozzle with Atomic method after I switch filaments. Should I sink my nozzle to acetone? Here is a picture while printing with silver Ultimaker PLA. Tried to raise my nozzle temp from 210°C (default PLA profile) to 220. Helped a bit but still happening every once in a while. With ABS (picture with black print) I've been having sort of under extrusion I believe? Any suggestions what to do?

Ah looks like I thought set screw to be something else. Anyways I wiggled the block and it came down closing the gap. And it works beautifully again. Thank you all!

You are quite right, it does seem so that my ring with holes isn't sitting on top of the plate. Didn't see that myself, thanks. I'll try to move it down. Set screw also keeps heater element in place, right? So if I try to loosen it up a bit but not too much thus making it longer and it should get the nozzle more out?

Thanks labern and ultiarjan, will adjust this today back to normal. I guess this method is only for adjusting the gap between the hot-end-isolator and PTFE? To stick the nozzle properly out I need to disassemble hot-end to get it more outwards?

Hey, My fan shroud hits the right hindmost glass plate clip and thus interrupting my print. I changed the nozzle a few weeks ago so I'm suspecting the reason might be that the nozzle is too deep in. Can anyone confirm this? I attached a couple of pictures. The other one showing the nozzle tip and the other is taken from collision point. Thanks in advance. [/media]

Okay, that is what I thought also; shouldn't have problems on nozzle cleaning. Many thanks!

One question occurred my mind: Does it matter do I use PLA or ABS for nozzle cleaning regardless of what I have been printing with? I changed from blue ABS today to white ABS and decided to do Atomic method in between. However maybe my chinese ABS so rubbish that it just breaks and doesn't come off at all cone shaped. Then I used my Ultimaker PLA and it worked like a charm. Any thoughts?

Looks like I hadn't done enough of Atomic method to clean the whole nozzle. So far it seems to be working, I have a test print printing right now. I'll report if I have any more issues but I believe this may have solved it. Thanks DidierKlein!

I will try my best (again) to achieve this. Any tips for how to get the filament out correctly? Mine breaks very often.. I've been trying to hold some pressure while nozzle cools down but no luck so far.

I thought so too but the problem exists also with Ultimakers PLA :/ Also we have completed many prints lasting 20-30 hours with eSuns ABS filament.

Hello all the wise, My problem with Ultimaker 2 is the feeder motor skipping and nozzle clogging. I'm not entirely sure if nozzle is clogged because of motor skipping or vice versa. Anyway: once i get the material flowing from the nozzle I do Atomic method. Sometimes I do get it out correctly and sometimes the filament breaks. If material flow is good then I have continued without successfully pulling out cone shaped filament (as described in Atomic method). After this I can make a few successful prints but after that the nozzle starts to clog again; though the feeder motor is skipping every once in a while when inserting material and trying to begin a new print after cleaning the nozzle. I've gone through various topics around this here on this forum but nothing has helped so far. I have tried these: - Cleaning the nozzle with Atomic method (sometimes though my filament breaks and doesn't come off correctly) - Changing the nozzle and teflon part (also the spring) few weeks ago - Sticking some wire inside the nozzle from below when nozzle is hot (this helps when it is jammed and no material comes out when manually feeding filament to nozzle like in Atomic method) - Disassembled the feeder and removing all the plastic particles inside and from knurled shaft We use ABS and PLA (several users) and we haven't done a proper clean up (like Atomic) after material change. We use Ultimakers 2,85 PLA and for a while we've had eSun's 3 mm ABS filament (2,9 mm±0,05). After changing nozzle and teflon only a few parts have been printed successfully before the problems started again. Overall we have printed some 700 hours with no problems and hence we thought the problems were caused by the teflon part. Is it possible that bowden tube could be worn from inside and cause too much friction? Anyone there to offer some more tips and tricks?
