Upgrade CR-10 V2 to BTT SKR V1.4 Turbo and How NOT to fry your Creality V2 .5.2 board with BL Touch

This video shows the disassembly of a working CR-10 V2 with the Big Tree Tech SKR 1.4 Turbo board before I cut new holes in the stock case to accommodate the USB and SD card ports on the TFT35 E3 V3.0 display and mainboard.

Sensorless homing with TMC2209 drivers and BL Touch are working fine, but due to limitations with the SKR 1.4, TFT35 and Marlin, filament detection only works when the TFT is in Marlin mode. The filament detector plug can only plugged into the SKR 1.4 OR the TFT35. Pick one or the other. See below for a link to Marlin 2.0.7.2 files. Grab the preconfigured Marlin zip for the CR-10 V2 and my files linked below.

I blew up my Creality CR-10 V2 while trying to install a 3D Touch (generic BLTouch) sensor. Do not follow any upgrade guides and plug your sensor into the 5-pin port on the back of your printer. Get your multi-meter out and check the continuity of the pins against the to Z-Limit plugs and D11 wire.

My 5-pin port wiring on the back of the printer (left to right):
1 - Positive 5V (servo positive)
2 - Signal (servo signal)
3 - D11 wire (endstop white signal)
4 - unknown (not negative. Do not use. If you hook the other negative wire to your SKR board, it will not boot)
5 - Ground (servo negative)

Leave the other 3D Touch ground wire disconnected as both grounds are connected.
