The Arm doesn't move, only filament comes out
The working start points are different for G-codes generated by Rotrics Studio and third-party software.
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).
If you set the working start point wrongly, the Arm movement will beyond limits, or when you click
startto start printing, only the filament squeezes out, the Arm won't move.
