Display1: bigtreetech TFT35
Display2: CR ender 3 LCD
Drivers: tmc 2208 (uart mode need welding a jumper)

NOTES:
As you can see, you need 8 wires for the hotend (2 wires for each fan, 2 for thermistor and 2 wires for heater)
E180 extruder board only has 6 wires, so I had to figure out how to do it. I appears than the 2 fans, and the heater share VCC.
SO IT´S a VCC share on the heater + connector for the three of then.
Bear in mind this, VCC is taken from HEATER0 + connector for cooling fan, partcooling and heater block. BE CAREFULL on polatiry when connecting heater cables.
See handwriting pic, schematics labeled as "PLACA" the number 6 pins.
Then, for the fans, only need to connect the negative (-) pins of the connector.
For the heater I rather liked to cut the cables out of the stock connector and weld it with a proper cable to He0 pins of the board.
In order tu hace usb access, I just cutted a usb cable, and welded cables to the stock back usb board, so can reuse the stock usb port at back of the printer.
Marlin 2:
Babysteeping enabled
Thermal runaway enabled
software endstop enable (size of 130x130x131)
THANKS to Carlos Arruti for letting me share the v6 stl´s.
UPDATE:
I noted that the TFT display is not many handy into advance marlin settings, so I open the drawer and found an old CR ender 3 LCD, so I decided to mount it.
There are to stl as well for this LCD (front and back). If you decide to set it up just like me, you´ll only print the front case stl. But if you´d like to set the LCD in the botton position you´ll need also the back stl.
UPDATE2:
Added a 40mm silent fan, enable only when the drivers and enabled and lasy 60 secs after the last drivers is disabled.
UPDATE3:
Now case fan y connected to always on fan, and installed a HEATED BED.
Upgrade to a 12V10A psu.
UPDATE4: Tried and esp3d module and didn´t like it much. Cheap buy useless. So I wen´t for a raspberry pi with octoprint.
