This Display Panel can take the place of Computer most of the time, but files in TF card still need Computer to create it.


The Display Panel has only one knob, the knob can rotate left and right and press down.

  • Rotate: change the menu item to be selected, change values, change engraving speed, etc..
  • Press: pop-up menu, confirm the choice.

Just need to download the last firmware file, unzip to the TF card's root directory.
