CR-10 Bootloader Flashing Video Guide
We recommend you use the video to flash your bootloader. The Instructables version is outdated now.
This is the guide you need to flash the bootloader for the CR-10, CR-10 Mini, CR-10 S4, and CR-10 S5.
UPDATE: The new CR-10 Board does NOT have a jumper on it. You can still flash just skip the jumper step. If you have jumper MOVE IT BACK to VREG when you are done. Make sure you select Arduino as ISP for the programmer or it will NOT work!
THE CR-10S (Any printer that has the 2560 and filament sensor from creality) DOES NOT NEED A BOOTLOADER.
Hardware is required and we sell a kit here: TH3D Uno Bootloader Flashing Kit
Anet Printer Flashing using the TH3D Uno Bootloader kit
Some Anet boards have an outdated or oversized bootloader. If you get a blank LCD after flashing you will need to flash the bootloader on your board. There is no physical way to tell what bootloader you have on your board without pulling it off with a programmer. If your Anet board resets when trying to flash you will need to flash the bootloader. Pinout is on the firmware page for the programming header. We recommend using a USBASP for this OR our specific Uno kit (genuine ones may not work).
If you use our Uno to flash please follow the the CR-10 bootloader guide video above but use the Anet pinout below and select the Anet V1.0 for the board instead of Sanguino.
