The primary function of this executable is to facilitate communication between your Windows-based computer and the printer's mainboard. When you plug a 3D printer into your computer via USB, the computer needs to recognize the hardware. Without the correct drivers, the printer will appear as an "Unknown Device" in Device Manager, preventing you from sending G-code files directly via slicing software like Cura, Simplify3D, or the proprietary Tronxy Slicer.
Once installed, connect your printer via USB. The software should automatically recognize the COM port if the drivers from the installer were applied correctly. Safety and Security Concerns tronxyinstall.exe
