Kingroon KP5L Firmware to Download

Dear Kingroon 3D Official
I forgot to inform you that I am basically using the same slicer thus the same g codes I use for KP3 and KP3S.

Dear Kingroon 3D Official
Just got my KP5L (half assembled) and assembled without any problem.
It halts somewhere soon after I start printing. Temperature setting and the head position stays as it is until I cancel the printing.
It sometimes ignores the Z axis limit switch (I diid the leveling procedure beforehand) and engraved deep scratches to the printing bed. After I stopped the printing, the printing head (Z axis) always goes all the way up till it hits the top and for a few seconds tries to force upwards producing odd sounds from the step motor.
I found the firmware here and flashed my printer with success, but the situations did not change. I had to invert the X axis setting in the cfg file which worked, but the problems with halts and wierd Z axis movements did not go away.
I am a huge fan of your products (I own KP3 and KP3S 1.0 which I upgraded to 3.0 by myself thanks to your instructions. They work like a charm.) and would very much like to have this KP5L work properly. Is there any information I should give you?

Firmware has been updated.
The startup logo changes to a strange image, followed by repeated reboots shortly thereafter.
The menu screen does not appear.
Please fix as soon as possible.

I did the firmware, but the printer is malfunctioning. I can’t seem to get the coordinates. I need a firmware that can be initialized.

Скачал прошивку на Kingroon KP5L. Обновился. Ось X инвертировалась, вместо права едет влево.
Downloaded the firmware on King room KP5L. Updated. F X was inverted, instead of the right goes to the left.
