Update again:

Changed Nozzle to 0.6 instead of 0.4 and removed the fan duct, now it works again. No skipping.
But the mystery remains... will it start skipping again if I go back to 0.4...

Update:

Up until now I've printed with the heatbed set to 60 C. I turned it off, and was able to print at normal settings, 190C, 100% speed for two hours without clicking. Then the clicking...

Thanks again for the answers! I really appreciate it! :)

Some new info from my tests:

From the beginning it works good, starts to skip steps with certain settings (too cold and/or too fast)....

I don't seem to have a part like that. If it can be seen in my latest image, can you point out which one it is?

I printed at 240 degrees at 50% speed now for a few hours, it went ok. Until the...

Hi again, thanks for your answer!

What exactly is the PTFE lining? I disassembled the extruder. Looks like the tube leading town to the hotend is a bit bent. But that shouldn't create too much...

I tried 190-240 degrees, and 20-120% speed. Before I've printed at 190 degrees at 120% with no problems. The only combination I found working now was >235 degrees and <40% speed. Colder or faster...

Found a video that shows exactly what happens inside:

Tried to print with slower speed, 60%, did not solve the problem. Tried to turn off retractions in the settings, did not work.



I see, thanks for the info :) I don't think that is what happened...

You mean the settings in your file was randomly set to 3 mm? I had a look but my settings in Simplify3D is still 1.75 mm.
Which printer do you use? How should reset printer to factory settings work?

Hello again!

Before I've been printing at 190°C at 120% speed for hours with no problem.
I tried to put speed at 100% and temperature to 210°C, now it printed the model without making a mess....

I don't think so, I opened it up and made sure nothing was in the way. I manually pushed a bit of filament through to clear out eventual junk but the problem persists.

I tested printing with an...

Hello! A strange problem occured which I don't know the cause of.

I've been printing with this PLA filament every day for a few weeks now without a problem, ~8 hour prints at 190°C with heatbed at...

Thanks for the answers!

I tried 5% with PolyFlex, grid pattern. It's very solid still. Buttons are quite small, only 1-2 cm o. So I switched to 0% infill, but it's still very solid, because of the...

Hello! I have a project where I need to print push buttons. It's not going to be mechanical, but instead squishy, like rubber.
I tested with PolyFlex, and when having infill it's quite solid, so it...

Bumping with a question that I didn't get answered:
Which one is better, Trinus or Prusa MK3? In terms of printing quality, and features (easy to use ect).

Is the Prusa or Qidi better than the Trinus you'd say?

Thanks for the answers! I'm in Sweden, but when speaking internationally I always use USD so that people wont have to convert my numbers.



Cool! The Qidi seems badass. I'm a noob though, but I...

Hi! I'd like to ask for a little bit of help, I'm currently looking for a 3D printer to buy. Preferably a cheap one, under 700 usd. I need it to be able to print Flex material and PLA/ABS. Would be...
