UART MOD FOR 4.2.2

[Boomklimmer]

Hi Guys,
I want to do the UART Conversion based on this Form:#1259.

I want to do this because I have a BMG Clone and the TMC2208 Just shuts down with Linear advance. Too many steps, too quickly.

I am currently using this config

Printer:ender3v2
BOARD:422
LEVELING: BLT, UBL
DISPLAY:DWIN
FEATURES
-CVLM
-HOMEOFFS
-IS
-LA
-MPC

Unfortunately, I have a C6 and not a T6 processor when compiling all of this, I get an error: region `FLASH' overflowed by 8380 bytes
Space is all taken up what can I let go for this UART mod?

I have disabled
-MPC
-The filament ran out but what else can be thrown away Besides IS and LA?

@mriscoc thank you for the reply, I decided to go with the Big Tree tech SKR mini V3 as it has UART and better stepper motor drivers out of the BOX. I tried to use the special configurator:

And I am struggling to get the BLtouch working. I have tried the 5-pin and the 3+2-pin methods but with no success. The blue light on the BLTOUCH comes on for a fraction of a second but then disappears.

I have downloaded this preconfigured file and the issue is solved:

would it be possible to share the Configurations for this so that I can see what the difference is and change the configuration for the SKR MINI V3 to help solve this issue? I will send the Config Files back to you with the change after testing has been completed. I want to add LS and Pressure advance to my build

Thank you for all the hard work on this firmware

Hi, you should get the same result if you just select Ender 3V2, SKRM3V3, BLT, UBL, DWIN, T1 and MPC in the Configurator.

OK, let me try and work back from there :)

I will post my findings

Hi to anyone using the SKR MINI E V3 Don't fall into the trap of selecting CVLM
.

Thanks @mriscoc for sending me on the correct path.
