This may be a little long but here it goes.
I got a Ender 3 V2 for Christmas. I have yet to get a print out of it. Many emails back and forth with Creality support and the glass bed and the controller board have been replaced. Still cannot print.
Here is the issue:
Leveling the bed at all 4 corners using a .104 feeler gauge with bed heated up, nozzle will drag on the bed in the center area. Adjusting the Z offset in the center results in filament not sticking outside the center area.
Leveling the board normally and trying a 1 layer test print results in the nozzle dragging in the center and either causing the extruder to click because nothing can come out or it will ooze out and become a clump on the hot end which it will then proceed to wipe the bed clean and everything gets stuck to the hot end. I have blown through 4 spools of filament spent countless late nights and entire weekends to get this thing to print and it just wont. Creality seems to want to fire the parts cannon at it rather than replace it.
I am pretty sure that the top part of the printer (frame) is the issue.
Things I suspect may be the issue:
Rollers are not concentric.
X axis channel is not machined straight
X Axis beam is warped/bent
Z Axis stepper has got a case of the jitters
I have completely disassembled and reassembled this printer 5 times. Creality actually sent me a 4.2.7 board which is even more quiet than the 4.22 board. I have not seen any negative reviews on this printer and can only assume I got a defective / lemon.
I have even tried custom firmware sent to me by Creality.
I just downloaded the bugfix release of the latest marlin 2.0.x and installed that . . . No Dice!
If anyone has any ideas or has encountered this issue I would gladly like to hear from you!
