In the list of Firmware builds I don’t see a download for Ender 3 Pro With 4.2.7 Board? Is there a reason for this?
The firmware is the same between Ender 3 and Ender 3 Pro systems.
There is no difference between the two as far as firmware goes - just physical differences that do not alter anything related to firmware - such as power supply brand and the thickness of the Y mount.
