  • For laser engraving, maker sure you have adjusted the focal length and set the origin position

  • For writing/drawing, make sure you have set the start height value

  • For 3D printing, make sure you have set the start height

3. Click SD card

4. Choose your G-code file

5. Click Startto work offline

Touchscreen Recalibration

Touchscreen recalibration is added in Touchscreen firmware V1.1.0 or above. Please confirm your touchscreen firmware version before recalibration.

Method 1: Touchscreen > Setting > Factory Reset > Touchscreen Recalibration

Method 2: Add an empty file named "touchscreen_recalibration.conf" to the directory: sdcard\firmware. If the Touchscreen reads this file during startup, it will enter the recalibration.

SetWorkOrigin & SetWorkHeight Difference

For G-code generated by Rotrics Studio, the working start point is X0 Y300. So when 3D printing with the touchscreen, you need to set G92 Z0 E0 (Set WorkHeight).

For G-code generated by third-party software, like Cura, the working start point is X0 Y0. So when 3D printing with the touchscreen, you need to set G92 X0 Y0 Z0 E0 (Set WorkOrigin/ Set Origin).

Note: if you set the working start point wrongly, the Arm movement will beyond limits, or when you click start to start printing, only the filament squeezes out, the Arm won't move.
