This is simply a warning that the throttle needs to be calibrated and that you will need to adjust the high and low voltage readings in order to use it correctly. The process for this is outlined in the next video and once you have completed this task the controller will stop beeping and you can proceed to changing the other settings. Once you have downloaded the file, click on Upload custom firmware and select the previously downloaded .hex file. To do this you’ll have to go to BCN3D’s github respoitory and download the latest firmware version in .hex format that you’ll find inside the Compiled firmware folder.

Low-level firmware is typically stored in non-volatile read-only memory chips such as ROM. This means you cannot overwrite or update low-level firmware, which means that low-level firmware is an intrinsic part of the hardware. A device that contains low-level firmware has one-time programmable memory. Hardware manufacturers can use embedded firmware to control multiple hardware systems and devices. The idea is similar to how your operating system pushes updates to the software on your device. The difference here is that firmware installation takes place upon manufacturing the piece of hardware.

Ideally also delete cache for before you attempt a new download. Programs that create HEX records typically use line termination characters that conform to the conventions of their operating systems. For example, Linux programs use a single LF (line feed, hex value 0A) character to terminate lines, whereas Windows programs use a CR (carriage return, hex value 0D) followed by a LF. These examples show the process of creating a Universal Hex. A V1 and V2 hex can be combined to produce a Universal Hex. If you can only support a V2 board, the standalone error can be combined with a V2 hex to produce a hex that will fail with an error on a V1 board, rather than failing silently.

This certainly happened to me when I changed my previous hotend for a new all-metal one. The difference in sizes created an offset of about 14mm that needed to be accounted for. Double check in the Info menu that the expected firmware version is shown.
