[does not connect with ender3 and skr mini e3 board]

Hello,

I also have a Creality Ender 3.

With Cura v4.3.0 my new BIGTREETECH SKR mini E3 v1.2 card does not work.

A sound like siren, frozen screen and button that does not work anymore.

The same symptoms as in these videos here:

I found these two solutions:

1) That given by Tjaart Bester in the comments of this video:

 

2) That given by martinways here:

Thank you to these two people.
 

Quite simply, you have to comment lines of the file AutoDetectBaudJob.py which is in the directory:

c : \ Program Files \ Ultimaker Cura 4.3 \ plugins \ USBPrinting \


Solution 1:

Line 33 # try:
Line 34 # programmer.connect (self._serial_port)
Line 35 # serial = programmer.leaveISP ()
Line 36 # except ispBase.IspError:
Line 37 # program.close ()


Solution 2:

Line 31 # program = Stk500v2 ()
Line 32 serial = None
Line 33 # try:
Line 34 # programmer.connect (self._serial_port)
Line 35 # serial = programmer.leaveISP ()
Line 36 # except ispBase.IspError:
Line 37 # program.close ()


These two solutions work, I can now use Cura v4.3.0 with the SKR mini E3 v1.2 card.

I hope this can help several makers.
