A speaker needs a AC or a pulsed DC to make a sound, a buzzer only needs a DC. A buzzer has it's own resonator. It works in most cases to feed the buzzer with a pulsed DC, but the sound will not be as loud as with pure DC. There seem to be boards where the BEEPER-pin is not able to handle a PWM. Obviously intended for a buzzer. To make these board able to handle a speaker * replace the PWM based tone()-function again with a on-delay-off-delay loop. Hopefully the last time I touch the beeper code. |

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
- 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/Configuration_DUAL.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
