  • Page 45: Setup/Print

    1. Communication Driver ANYCUBIC TriGorilla mainboard uses CP2102 as communication chip. When you connect Anycubic i3 to PC for the first time, the system should install the CP2102 drive automatically. Open “Device Manager”, choose “CP2102”, right-click it and update the drive. Otherwise you could find the driver for manual installation via the link above.
  • Page 46 Attention: the serial port should be the same as the Device Manger (on your PC) shows, AUTO will not be accepted. Other parameters: (Cura will show the corresponding information when mouse stays on the icon) Print speed: printing too fast may make printer shaky, 20~60 is suggested. Printing temp: PLA should be 190~210℃, and ABS should be 230~240℃.

  • Page 47: Leveling

    2. Leveling The level of first layer is the base of a model, and it matters for the print quality. For ANYCUBIC i3 printer, it’s convenient to level the platform manually, and you don't need to level it every time.

  • Page 48: Faq

    1. PC cannot identify the motherboard. Please refer to part one in the Setup/Print section. 2. Slicing software cannot comunicate with printer. For CURA, you have to choose the right serial port (not Auto). For other slicers, we have to select the right baud rate too, and we’ve set is as 250000 in the firmware.
