# Felix 2.0/3.0 Configuration for Marlin Firmware
Bringing silky smooth prints to Felix.
## Build HOWTO
- Install the latest non-beta Arduino software IDE/toolset: http://www.arduino.cc/en/Main/Software
- Download the Marlin firmware
- [Latest developement version ](https://github.com/MarlinFirmware/Marlin/tree/Development )
- [Stable version ](https://github.com/MarlinFirmware/Marlin/tree/Development )
- In both cases use the "Download Zip" button on the right.
```
cd Marlin/Marlin
cp example_configurations/Felix/Configuration_adv.h .
```
The next step depends on your setup:
### Single Extruder Configuration
cp example_configurations/Felix/Configuration.h .
### Dual Extruder Configuration
cp example_configurations/Felix/DUAL/Configuration.h Configuration.h
### Compile Firmware
- Start the Arduino IDE.
- Select Tools -> Board -> Arduino Mega 2560
- Select the correct serial port in Tools -> Serial Port (usually /dev/ttyUSB0)
- Open Marlin.pde or .ino
- Click the Verify/Compile button
### Flash Firmware
#### Connected directly via USB
- Click the Upload button. If all goes well the firmware is uploading
#### Remote update
Find the latest Arduino build:
ls -altr /tmp/
drwxr-xr-x 5 chrono users 12288 Mar 3 21:41 build6072035599686630843.tmp
Copy the firmware to your printer host:
scp /tmp/build6072035599686630843.tmp/Marlin.cpp.hex a.b.c.d:/tmp/
Connect to your printer host via ssh, stop Octoprint or any other service that may block your USB device and make sure you have avrdude installed, then run:
avrdude -C/etc/avrdude.conf -v -v -v -patmega2560 -cwiring -P/dev/ttyUSB0 \
-b115200 -D -Uflash:w:/tmp/Marlin.cpp.hex:i
