Ender-3 4.2.7 Board Upgrade problems
I have an Ender-3 with BL Touch it was running on a 1.14 mainboard. I have upgraded to a 4.2.7 mainboard and downloaded the firmware from this site.
I have modified the BL touch cabling to plug into the mainboard. When I start the I can set the Z-Offset, it will not run Bed Level, and when I attempt to print it homes as expected makes a funny noise then moves the head to the right and obviously crashing at that end forcing me to stop print. What can I do other than going back to the 1.14 board. Does anyone have working firmware I can download and test as the firmware from this site doesn't work.
