The minimum time in processor ticks, each segment must need if the cache is low. The default value means, there will be still 40 segments printed per second.Trajectory smoothingThe firmware uses the bresenham algorithm for the computations of the x, y, z and e axis. It takes the axis ...
Sidekick Basic Kit for Arduino V2 The Arduino Sidekick Basic Kit is designed to be used with your Arduino / Seeeduino / Seeeduino ADK / Maple Lilypad or any MCU board. It contains everything needed for a first-time user to connect his/her computer to an Arduino. It includes many of the ...
