Hello
My new printer Ender 3 Max suddenly stopped all fans.
I check the fan and the mainboard and wrote to creality for help, because the printer is only a few weeks old. (I think the fuse F3 is broken )I hope they can help me, warranty.....and more.

I looked in the internet, which mainboard i can use for the printer. Currently its the mainboard 4.2.2 with TMC2208.
Can i use the same mainboard, which is for the ender 3. I found this 4.2.7 board:

Thank you for your help.

Thank you

I did it before I read your answer.
I have a lot of problems with the z axis roller, because thus are 6 pieces.
Please, can you prefer a YouTube video? I searched one, but didn‘t find anything...

I prefer German videos, but if it is in English, I can understand it, but it’s a little bit difficult.

I removed the z-axis to pull it by hand....
I lost my feder. When I reinstalled the y-axis, I couldn’t compress the feder. Now it looks like the picture
Is it a problem?

Hello

I leveld it and checked the Extruder settings.
Today I want start my first „real“ object. A CUBE 20x20x20mm

I have a problem always on the same height... the cubic got a „blob“ on the layer height. Look at Max picture, please.

What’s wrong?!

Hello
I'm new in this forum and want to say "Thank you", for the existing website
Sorry for my english, it is not my native language.....

I got my ender 3 max printer and want to change the fan of the mainboard.
I found the original fan in the web, but i want to use a other model.
I think the stock fan ist the: PD4010MS4
So i need to know the specefications:
airflow ?m3/h
Rounds per minute /rpm
24v (like web details)
Does i really need 24v fans?

Thank you for your answer!
