MPCNC-PRIMO-BUILD

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
http://reprapelectro.com/wp-content/uploads/2014/07/RAMBo-Driver.zip

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

• Marlin

• Configuration.h

• Configuration.adv.h

• Version.h

• _Bootscreen.h

Select sketch > upload

wait.....

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.

V1CNC_Rambo_Dual-2.0.7.2-src.zip

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.

WIRING

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.
