Using normal ribbon cables you will almost certainly get garbled data on the screen,
You might get away with using screened cable but i doubt it, not at 5 feet.

You probably damaged the track that feeds power to the FET gate pin.
solder the 100k resistor from the gate leg too ground and allso scrape some of the feed track and conect a wire from the gate leg to the track, see attached pic.

Yes you can solder to any part of the copper you marked in red, you can solder the other end of the resistor direct to the leg of the FET gate leg if its easier.

Do you mean skirt or brim ?
A skirt is normally printer a certain distance away from the object and is preset in the slicer settings (adjustable).
A brim is several loops around the object and attached to the outer perimeter of the object (normally used to increase bed adhesion of the object).

Printing
In config.h find this line
#define DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 }
change the 5 to a 2
5 is normally too fast for most printers.

To rule out if it is firmware or host have you tried a different host like pronetface or mattercontrol?

Firmware - Marlin
You say the first pic is after a G28, yet the X carriage is no where near the X endstop.
Does the X and Y stop at the endstop switches when you send a G28 ?
What are your home position values for X and Y in firmware? from the pics it looks like you might need a negative value,distance from nozzle to bed edge when X and Y are homed .

If you have a spare 1/4 watt resistor around, it might be neater to using a leg of the resistor between Q1 gate and R32, apply some solder to the wire 1st then solder it to the part,you will find the solder runs a lot smoother .
Glad your getting there

acording to the circuit, Q1 gate is connected to R32,
2 options . try scraping some of the white coating to see if you can uncover the broken track to connect too.
or maybe solder a wire between Q1 gate and R32. as in the pict.

The X endstop is mounted on the back of the X carriage and acts as a MIN endstop
The Y endstop is mounted top rear of the frame, this is a Y MAX location
The Z enstop is mounted top rear of the frame, this i s a Z MIN location
In S3D when you send Z- the bed should move upwards toward the hotend, Z+ should move the bed downwards
In your config, you have the Y endstop set as Y min

Unfortunatly the white surface makes it very hard to see where the wanted track is,but i suspect it goes back behind the fet and under the heatsink.

Are you printing from SD or a host,
If host, check the bed sizes are still set correctly.

QuoteAs I figure it, the X-axis motor should be Clockwise Y-Axis Anticlockwise and Z- Axis with lead screw I guess is Anti-Clockwise. Is that correct?
correct.

Allso make sure you have set Y max homing in S3D

Are you measuring the resistance with the thermistor disconnected,(hopefully)
What meter are you using ?

Prusa i3 and variants
Ok, so the pad on the bottom of the board is not needed for tha gate leg of the FET, the track the gate pin solders to is located on the top (component side) layer.hopefully you still have enough of this track left to solder too.

It looks like you have soldered the grid pin to ground, this is the right hand pin in your photo, it should be a small solder pad, not connected to the large mass.

your Z max feedrate is set too high in the line below
Quote#define DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 }
change the 5 to a 2 and re upload firmware.

Click the green button and download the zip,it will contain the whole firmware package. Yes you will need to make changes to the configuration.h before you upload the new firmware to your controller.

G32 is if the bed is perfectly flat. if you want to use the distortion corection for a bowed bed, use G33 (uses a different set of probe locations bottom of general tab)

Printing
ok, some things i would change in the dev config
Homing order use Z up X Y preheat Z
Your P1,P2,P3 probeing points did not make sense
I have made these changes in the attached config. give it a try and report back.
after uploading new firmware dont forget to update eeprom with
M502
