Prusa MK3 + Multi-Material-v1
How to make it work
- A 5 pin connector is needed to replace the 4 pin connector on the cable end that connects to the EINSY RAMBO board.
- The wires should be connected like [white][black][empty][blue][red] with the red wire being closest to the edge. See hardware folder for photos.
- Upload Firmware.ino.rambo.hex to your printer.
1. Development environment preparation
-
Install latest version of
"Arduino Software IDE"
https://www.arduino.cc -> Software->Downloads
-
Add (
UltiMachine
)RAMBo
board into the list of Arduino target boards
File->Preferences->Settings
into text field"Additional Boards Manager URLs"
type location
"https://raw.githubusercontent.com/ultimachine/ArduinoAddons/master/package_ultimachine_index.json"
or you can 'manually' modify the item
"boardsmanager.additional.urls=....."
at the file"preferences.txt"
(this parameter allows you to write a comma-separated list of addresses)
note: you can find location of this file on your disk by following way:
File->Preferences->Settings
("More preferences can be edited in file ..."
)
than do it
Tools->Board->BoardsManager
from viewed list select an item"RAMBo"
(will probably be labeled as"RepRap Arduino-compatible Mother Board (RAMBo) by UltiMachine"
'clicking' the item will display the installation button; select choice"1.0.1"
from the list(last known version as of the date of issue of this document)
(after installation, the item is labeled as"INSTALLED"
and can then be used for target board selection)
2. Source code compilation
run "Arduino IDE"
; select the file "Firmware.ino"
from the subdirectory "Firmware/"
at the location, where you placed the source codes
File->Open
make the desired code customizations; all changes are on your own risk!
select the target board "RAMBo"
Tools->Board->RAMBo
note: it is not possible to use any of the variants "Arduino Mega …"
, even though it is the same MCU
run the compilation
Sketch->Verify/Compile
upload the result code into the connected printer
Sketch->Upload
or you can also save the output code to the file (in so called HEX
-format) "Firmware.ino.rambo.hex"
:
Sketch->ExportCompiledBinary
and then upload it to the printer using the program "FirmwareUpdater"
note: this file is created in the directory "Firmware/"
