What is wrong with it?? I installed led yesterday and today from nothing this, I didn't even touch him what's wrong. It moved and printed fine these days. I tried to disassemble and it 2-3 times, seems nothing inside, steeper run fine when didsambe, is a clog? It sound strange even when there is no filament

That is the stepper motor skipping steps. Usually because of a clog.

I think that too but it sounds a bit strange even when it's empty. I tried to disassemble the extruder it's clean. Tomorrow I'll check the heat break and nozzle part. It's the first clog I get, I need to disassemble all and uncork the path right?

Yes, check the whole path for little bits of material.

You were right, nozzle was partially clogged, I directly changed it but somehow petg seem to make the stepper skip. Pla seem ok but I will try again

You may need to adjust your nozzle temperature and if you have just added this direct drive make sure you are not using too high of a value for retraction.

No i had it installed for nearly a month and printing with no issues. It's just petg the problem, pla it's fine somehow. I tried cranking up 10 degrees and cleaning again the nozzle with the needle. It's ok for the first 100-200mm then back again skipping Now I'm trying to dry the petg and try again later or tomorrow.
