Re: Common problems/Tips and tricks
Another reason could be that the extruder arm is broken or not properly tensioned.

Has anyone encountered problems with the bottom layers curling up from the heated bed? I'm printing at 195° with the bed set to 55°.
Yes, I've got that a few times but did not find any cause.
First I supposed the second extruder to be lower that the first one and thus hitting the bottom layer, but taking a closer look at it, this was not the cause.
I next supposed the bed not to be leveled well, but later on I just tried to print the faulty element again and then I didn't happen a second time. So - at least for me - it seams to happen "randomly" ... which I know can't be, but for now it's that :-/

Guys, I think that I found the main reason for this trouble. I had also this kind on trouble and I found the solution for this trouble - I had none of this kind of trouble anymore, at all. So, when the hot-end heats up the nozzle then the hole in PEEK insulation getting smaller. I think that it has too accurate hole, and I just drilled it little bit bigger - I drilled it to 2,5mm at first, later I did new one, and drilled 2,25...2,3 mm hole.
Because I had many issues in hot-end in the beginning, I made many different type of hot-ends and final version of my none-issues hot-end is in here - https://grabcad.com/library/extruder-fo ... nter-2-0-1

Why the filament does not stick onto bed? Just clen it with acetone when it 40...50 degrees - I clean the bed once after 4 or 8 printing time and I do not have any problem with not-sticking. Also I found that I do not have to change kapton so often at all - 1 roll for year is quite enough.

It's not a matter of the filament not sticking to the bed. The filament is actually curling up from the bed. After a few layers the print head hits it and knocks it out of alignment.Jaanus wrote:Why the filament does not stick onto bed?

Make sure the bed is tightly calibrated. even 0,2mm out of alignment is a complete layer height. Then, while printing the first layer, adjust the Z spindle (Just push it through the steps) that it really smudges the first layer into the bed. If it’s still curling, buy these stickers for a way better adhesion:

I've been printing mostly ABS on my new 3.0 printer, and I had some bed-adhesion problems at first too! Corners warping upwards etc...
I use the Kapton sheet that came with the printer, heat the bed upto 100 degrees celcius, and aply a thin layer of ABS slurry (abs and acetone)... Now I've got problems getting the parts off rather than getting them to stick!
