Printer Notes​

This config will be for a stock UMO with a 1.5.7 board, UltiController and a 12×3 Leadscrew. If your printer differs from this please take some of the following into account.

Print Area
Advertised as 210x210x205 the Marlin config is 205 cubed.
XY might reach 210 with the endstops at their far positions. My X hit at 208.
Z I have set at 200 to start for safety. 205 is fine if you don’t have a magnet/sheet on the bed.

Z Speed
Keep in mind this thing is made of plywood. The Marlin config has Z homing at 4 mm/s. You can probably go a little faster with the 12mm leadscrew but I would not bump it up too far unless using the 8mm setup.

Installing Klipper​

Please see our overall guides for installing Klipper on your Pi/Printer via MainsailOS or KIUAH

MCU Firmware Make Settings​

sudo service klipper stop
cd ~/klipper/
make menuconfig

If this is a fresh klipper install you will likely find the defaults of Atmega AVR and atmega2560, that is what you need.
Hit Q and save then enter make to compile the firmware.

make

MCU Firmware Flashing​

Ultimaker boards can be flashed over USB, in this case directly from the pi after compiling.

Query your boards unique id using the following command:

ls /dev/serial/by-id/*

In this case our device id is /dev/serial/by-id/usb-Arduino__www.arduino.cc__0042_74133353437351A0A241-if00
You will need to substitute your id but in my case the command to flash the firmware will be:

make flash FLASH_DEVICE=/dev/serial/by-id/usb-Arduino__ www.arduino.cc__0042_74133353437351A0A241-if00

After a successful flash don't forget to restart the Klipper process with:

sudo service klipper restart

Upload your printer.cfg. Remember to replace the serial id with your boards unique value.
