# 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 `start` to start printing, only the filament squeezes out, the Arm won't move. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
