When the bootloader is done burning, carefully disconnect the jumper wires from your Ender 3, secure the control box cover, and unplug the Arduino from your computer. If you're using a Mac, don't forget to follow the Mac setup instructions for the TH3D Arduino IDE.Īvrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x14Īvrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x01Īvrdude: stk500_initialize(): (a) protocol error, expect=0x14, resp=0x10ĭouble check connections and try again, or use -F to overrideĪvrdude: stk500_disable(): unknown response=0x12
Then, select Sanguino (1284P Boards) as the board. If you see an error such as the one below (especially if you're running macOS), try installing the TH3D United Firmware Package and running the included preconfigured Arduino IDE instead of the normal Arduino IDE.Select Boot macOS Install from Install macOS High Sierra/Sierra/Mojave and press enter to boot. Select your USB with the UEFI prefix and it will boot to clover. Plug the USB flash drive in USB 2.0 port and boot to boot menu. Make sure you downloaded the Arduino IDE directly from the Arduino website (not the Windows store) After preparing your installation USB, you're ready to install on the target laptop.Swap out your jumper wires in case yours are defective.Double-check your settings and connections.If you run into issues, try the following: When the process is finished, you'll see a message stating 'Output bootloader burned successfully'. Then, change the Programmer from AVRISP mkII to Arduino as ISP. Select the Sanguino board from the Tools menu.
