I used yard sticks to get the layout correct. This way I only had to be accurate on the diagonals.
I added a jumper to connect the motor and mosfets power just + to + and - to -
My plan is to use the fan mosfets to power the cooling fan.
Any downtime between prints start printing your cable management early.
Plan for 3 days of nonstop drag chain printing.
first for windows install the usb driver
just unzip this and right click on the .inf file and select install
Hook up the usb cable.
Open the Arduino IDE
Set the board to be a mega 2560
set the com port to be correct
unzip the firmware
open marlin.ino in the Arduino IDE
you should see 5 files listed
Select sketch > upload
this takes a while
NOTE: I like to add a very stupid little thing where I add a > to the CUSTOM_MACHINE_NAME
This is so I can look at the screen and know that it took the files I wanted.
A preconfigured Marlin Firmware is preloaded onto the board. To re-flash this board, you can simply use the Arduino IDE and set board to "Arduino Mega 2560". There is also a Arduino plugin folder on github that exposes additional pins in the Arduino IDE.
UNPLUG YOUR CONTROLLER WHEN YOU MAKE ANY WIRING CHANGES THIS IS NOT OPTIONAL
I will only post things I find now covered in this page
The wiring was fun. I ended up adding the extension cables and drilling extra holes in my boxes.
