Hi, I am starting to have a problem with my MP3DP especially with the MK8 extruder. Since some time the extrusion doesn’t seems constant. When printing the first layer I start extruding perfectly then at some point the filament output by the extruder becomes very tiny and up to a point where nothing gets extruded. I tried to adjust the screw on top of the extruder which I think sets the tension and also replace the nozzle but nothing works.
For the first time today I can hear that either the motor skip steps or the gear grind the filament but clearly the filament is not provided evenly.

How long have you been using it, has it worked flawlessly until now?December 16, 2017 at 2:09 pm #49595
Yes I am using it for quite a while, several months maybe a year. The first layer was always a challenge as I need to adjust the bed almost every day that’s why I installed a BLTouch but now I can’t really benefit of the autoleveler since the extruder is not working properly. The problem start before I installed the BLTouch, just to clear that it is probably not related.December 16, 2017 at 2:12 pm #49598
Chances are good your PTFE liner has crapped out. Various reasons but Mine last about 6-8 months of continuous low temp use. I switched over to the microswiss so I don’t have to deal with it anymore.December 16, 2017 at 2:23 pm #49600
That was my next step. Can you give me more info on the microswiss. Is it available at Amazon?
Also talking about extruder, I notice that you now sell the Titan Aero, do you recommend it over the MK8? It is more pricy so what would be the advantage going with it.
Since I have a set of 500mm rods I was planning to create a larger MP3DP and consider changing the extruder. Also is the parts for the new MP3DP you create available? The corners seems to support half inch structure. I am very interested.December 16, 2017 at 5:03 pm #49609That was my next step. Can you give me more info on the microswiss.

Ummmm, the biggest advantage is it is lighter and the parts are seriously high quality. Mine now come with the all metal throat (that WAS the other major factor), so you might be able to print a little faster, depending on your bed weight. Other than that it is quality. The import stuff, if you have seen, I have to offer as a kit now as the pre-builts are complete sh#t. The difference between the mk8 kit I now sell with the micro swiss throat and the Areo is not huge. If money isn’t that big of a deal get the aero, if every penny counts the mk8 will get the same job done. Hope that doesn’t piss of the E3D team. Don’t want to lose my account.Also is the parts for the new MP3DP you create available? The corners seems to support half inch structure. I am very interested.
Very very soon. I am printing with it non stop to make sure everything is legit then I will start releasing it in a few days I hope.December 16, 2017 at 5:39 pm #49613December 17, 2017 at 11:41 am #49649
Just to let you know, I change the metal threaded tube including the PTFE liner and my problem is solved. Thanks again! Feels great to have such support! I will look into the Microswiss for a more permanent solution.December 17, 2017 at 7:23 pm #49665
I used to just swap out the liners all the time, super cheap. I just got sick of taking it apart (6 printers it really gets old) that is when I found the microswiss stuff.
