Seems warped bed.Maybe glass will help.BL touch is not your issue i think.
Did you tried same model with raft?
Before homing and leveling your plate did you heat up until 65 degrees?
Why not printing first layer and upper layers at same temprature?

Hi,
First of all please watch below video:

You have to compile firmware yourself, follow directions on video.

4.2.2 boards have two variants of stepper drivers one of TMC2208 one of A4988.Try with TMC2208.In configuration.h.If doesn't work try with A4988.Once you compiled firmware do not rename firmware file name leave as is just put file in sd card and switch on printer it will automaticly loads itself.
Configuration.h related section below:

/**
 * Stepper Drivers
 *
 * These settings allow Marlin to tune stepper driver timing and enable advanced options for
 * stepper drivers that support them. You may also override timing options in Configuration_adv.h.
 *
 * A4988 is assumed for unspecified drivers.
 *
 * Use TMC2208/TMC2208_STANDALONE for TMC2225 drivers and TMC2209/TMC2209_STANDALONE for TMC2226 drivers.
 *
 * Options: A4988, A5984, DRV8825, LV8729, L6470, L6474, POWERSTEP01,
 *          TB6560, TB6600, TMC2100,
 *          TMC2130, TMC2130_STANDALONE, TMC2160, TMC2160_STANDALONE,
 *          TMC2208, TMC2208_STANDALONE, TMC2209, TMC2209_STANDALONE,
 *          TMC26X,  TMC26X_STANDALONE,  TMC2660, TMC2660_STANDALONE,

Hi,

I have my printer about 3 months and was very happy about it.

It was printing test cube succesfully before but now i have problems on X and Y letters as seen on pictures.Cube corners and letter corners are not good as before. Here is my parameters:

Material:Generic ABS

Nozzle temp:230

Bed temp:100

Slicer:Cura

Firmware:Marlin 2.0.7.2

Board Creality 4.2.2 with TMC2208

Printer is stock except glass bed and cooling fan (laptop fan driven by buck converter actually) mod that i invented from scrap laptop fan by myself because original fan is broken. It was printing fine with these mods before. I have MDF cabin and sound insulation on my cabin.Cabin insulation is not finished yet.

Things i have tried so far:

Changed nozzle.

Leveling bed so many times.

Thigntened belts both X and Y axis.

Checked roller bearings.

Tried with different nozzle temps.

Could anyone tell me what is wrong?
