This complete graphics controller includes an SD card reader, a rotary encoder and a 128 x 64 dot matrix LCD display. You can easily connect it to your Ramps board using the included "Smart Adapter". After connecting this panel to your Ramps, you no longer need your computer, the Smart Controller powers your SD card.
In addition, all actions such as calibration and axis movements can be performed simply using the rotary encoder of the smart controller. Print your 3D designs without a PC, only with a g-code pattern stored on the SD card.
