Change to v4.2.7 on Ender 3 Pro and smoke at power up
-
Hi all,
I just changed my 4.2.2 on my Ender 3 Pro to v4.2.7 to get some silence...
I took the opportunity to replace the hotend fan to a SUNON one with a DC/DC converter and also install a BLTouch v3.1...When I powered up the printer for the first time, I had some smoke so I switched everything off.
Here are the picture of the complete board and also the damaged area...
Any idea ?It looks like it is linked to the Y-Axis driver....
