Hi, If you remove the 3d touch, you can try to adjust the limit switch of the z-axis to manually level it;
Then flash the firmware back to the version without 3d touch.

A20M_G04(GT2560V3+CH340) its exactly w\o sensor - what you mean manual? i take it to lowest point with my hands - it`s manual?
I send the picture when i try to do home its lo low and no filament in the menu! Geeetech firmware is no good !!!

also w\o sensor you can see i take manual Z to a minimum it`s after HOME and A20M_G04(GT2560V3+CH340)

Hi, After you update the firmware without 3d touch, you need to level the hotbed.
You can try to raise the nozzle and then level it, or move the limit switch of the z-axis down to adjust;
Because your version is a Mylar version, the distance between the nozzle and the hot bed is the distance between the two leveling papers;
The video you provided shows that the printer can be turned on normally.

limit switch of the z-axis down its all-ready down - what is Mylar version? 2 papers it`s 1 mm?

The hotbed version of your printer is the Mylar version, not the glass plate.
The distance between the hot bed and the nozzle is the distance between the two leveling sheets.
