GCodeSimulator visualizes 3D printing gcodes and simulates the 3D print.It shows how your print will look like, allowing you to check your print upfront, making it easier to spot errors and fix them instead of wasting filament. In addition, GCodeSimulator can connect to many 3D printers using USB-OTG cable (or Bluetooth) to control the printer. The printer control panel provides the most important printer controls (e.g. XYZ Movement) for manual operations. This enables you to use any Android tablet or phone as a touch screen for your 3D printer.
