<p>The extruder motor makes these clinking sounds.

<p>It seems that if I have a print of 0.1&nbsp;mm layer thickness, the nozzle does not put out enough filament and it gets clogged up in the leading metal tube to the nozzle.</p>

<p>On the <code>extruder</code> side it looks like the clogging up gets the motor the sort of <em>skip</em> the push of the filament.</p>

<p>What is going wrong here??

The extruder motor makes these clinking sounds.
I read about that and I tried to adjust it with its potentiometer,
I tried reassembling the clamps, reinserted the leading tube in both ends, cutting them in a 90° angle but nothing helps.

It seems that if I have a print of 0.1 mm layer thickness, the nozzle does not put out enough filament and it gets clogged up in the leading metal tube to the nozzle.

On the `extruder` side it looks like the clogging up gets the motor the sort of *skip* the push of the filament.

[This](https://pastebin.com/embed_js/LZP3tq2E) is my G-code.

What is going wrong here??
How can I setup these params to work together smoothly?

The filament may also be too cold, and is providing too much resistance to being forced out the extrusion nozzle.

Or the filament may be getting stuck in the area just above the heating element in your hotend. This is called [heat creep](https://www.fargo3dprinting.com/how-to/heat-creep/), and can cause jams. Based on your description it looks like this is happening to your hotend.
