Original Prusa Curing and Washing machine firmware
You can get to the “hidden” settings menu by long pressing the rotator in the settings menu. Contains UVLED intensity, Factory reset, Cooldown and Selftest.
You can use the self-test to test the functionality of your device. The semi-automatic tests require your cooperation and are the lid switch test, the IPA container detection test, and the motor test (which visually assesses that the platform is moving). This is followed by fan, UV LED and heating tests. They will run by themselves, all you have to do is close the lid.
The fans are controlled in such a way that the device is cooled as best as possible. In some cases, the fans can run at full power, which can cause more noise. That's normal.
Due to the location of the thermistor in CW1 (not applicable to CW1S), the temperature measurement inside the device is relatively imprecise and is subsequently compensated. For this reason, the temperature is shown on the display after 2 minutes from the start of heating. Until then, “-- ˚C” is displayed.
Original Prusa CW1S or CW1 platform upgrade brings a removable platform protected with an FEP film. To help align the platform back to its original position, the user can activate “Hold the platform” from the menu. The motor gets “locked” (rotation is disabled) by the system, temporarily allowing the user to align the platform properly. Once the platform is properly seated, exit the menu to “unlock” the motor.
You need to install unzip, wget and make tools, next run the following command:
./build.shIt downloads neccessary tools, creates build subfolder, extracts tools to build/env, builds firmware using make and puts the result into build subfolder.
You need make, avr-gcc and avr-libc installed.
You can use the DEVICE=CW1 or DEVICE=CW1S parameter to select which device you want to build, the default is CW1S.
To build version with debug turned on use:
makeor with language code:
make LANG=xxThe file build/Prusa-CW1S-Firmware-LANG-devel.hex will be generated.
To build version without debug use:
make distor with language code:
make DEVICE=CW1 LANG=xx distThe file build/Prusa-CW1-Firmware-LANG-GIT_TAG.hex will be generated.
Configuration > Flash printer firmware, then fill up the path to generated .hex and hit Flash!
Board needs to be reset to bootloader. Bootloader has 5 seconds timeout and then returns to the application.
This can be accomplished manually by pressing reset button on CW1/CW1S (near microUSB port), or programmatically by opening and closing its virtual serial line at baudrate 1200.
Linux command (replace \<virtual serial port> with CDC device created by CW1/CW1S usually /dev/ttyACM<nr>):
stty -F <virtual serial port> 1200 crtscts; while :; do sleep 0.5; [ -c <virtual serial port> ] && break; done;Then flash it using following command, replace \<virtual serial port> with CDC device created by CW1/CW1S usually com<nr> under Windows and /dev/ttyACM<nr> under Linux. -b baud rate is don't care value, probably doesn't have to be specified at all, as there is no physical uart.
avrdude -v -p atmega32u4 -c avr109 -P <virtual serial port> -b 57600 -D -U flash:w:build/Prusa-DEVICE-Firmware-LANG-GIT_TAG.hex:iThere is known issue with ModemManager: you either need to deinstall it, or blacklist the Prusa Research USB devices:
/etc/udev/rules.d/99-mm.rules in order to add:

You need make and doxygen installed.
