Hello,
Thank you all so much for all the amazing information you have posted here. We just put together or Migbot Ultra Prusa i3 Diy Kit WITH the AutoLeveling Option (Proximity Sensor) from 3D Printers Online. This is the first time we have ever put together a 3D Printer. It took us roughly 4 hours to put together. It has the "MKS Base v1.3" Motherboard.
In general, everything seems to be working well when we drive it Manually. The movements along X, Y & Z seem to be fine. The Extruder and Heated Bed also heat up perfectly. And we are able to Extrude PLA perfectly. We moved the Print Bed all the way Forward, the Extruder all the way to the Right and relatively leveled to the Bed. And pressed "Set home offsets"
If we use the "Move axis" options, when we turn the dial, the Bed and Extruder move in, what we believe are the right directions. If we rotate the Dial to the Right, the Bed moves backwards till around 200 and when we turn to the Left it returns to the original position at zero. Same goes for the Y and Z. When we turn the Dial to the Right, the Y moves Left to 200 then, when we turn to the left, it goes Right back to zero. Z moves up when we turn Right, then down back to Zero when we turn it Left.

We calibrated the Auto-Level Proximity Sensor to be 2mm above the print head. However, we have two issues... and they are most probably related;
1. When we select "Auto Home",
a. The print bed goes ALL the way forward and starts grinding the belt teeth.
b. The Extruder moves to the Far Right
c. The Z-Axis moves DOWN... Hits the Limit Switch... but instead of stopping... it pushes the Limit Switch assembly DOWN trying to move past the Print Bed.
2. I tried setting the "Set home offsets"again. But when I try to start a print, it moves the head UP by around 4mm and begins Printing. in the Air.

3. We received a White Wire with an LED at the end. But have NOT IDEA where to plug it in??? Not sure if this is the LED jcabrer mentioned in one of his posts.

Right side Z axis mount was bad. Screw would bind. leveled the screw holder. X,Y and Z axis now run free.

Ran into a new problem. Loaded configuration.h into Arduino. Uploaded. It seem to upload alright since I had blue lights flashing for a second and it reported upload complete. Now I have two lines of squares the screen and lost display control. Reflashed several times with no luck. All I wanted is to enable auto leveling. Should left it alone since SD card worked. Any help?

How do I extract the current installed code from the MKS Base v1.3 board. I want to keep a copy of the original code just in case.
I think I have all the required softwares etc, but in Arduino IDE, I can't see the installed config h etc
avrdude.exe -C ..\etc\avrdude.conf -c usbtiny -P usb -p m2560 -U flash:r:migbot-flash.hex:i
avrdude.exe -C ..\etc\avrdude.conf -c usbtiny -P usb -p m2560 -U flash:w:migbot-flash.hex

You will not be able to see the code that's flashed on your board, but you can back it up in case you want to restore the firmware to what was shipped with your printer.
To read the contents of flash you need an AVR in-system programmer connected to the 6-pin ICSP header next to the micro. AVRDUDE is installed with the Arduino IDE under hardware\tools\avr\bin, but you'll have to run it from the command line.
I use a USBtinyISP, so I backed mine up to a file named migbot-flash.hex with the following command:
avrdude.exe -C ..\etc\avrdude.conf -c usbtiny -P usb -p m2560 -U flash:r:migbot-flash.hex:i
To restore:
avrdude.exe -C ..\etc\avrdude.conf -c usbtiny -P usb -p m2560 -U flash:w:migbot-flash.hex
If you use a different programmer, you'll have to change -c & -P to suit your configuration. Ladyada has a good tutorial on AVRDUDE which lists all of the programmers.
