Compiling Unified 2 Firmware

In preparation for the arrival of my Ezabl Pro from Th3d studio I have been gathering what I need for the install. I downloaded Unified2 firmware for the Ender printers. Installed and configured VSCode. In the configuration.h I uncommented Ender 3 v2 with 4.2.2 board which is what I have. One of the other options is for the stepper drivers, in none of the videos I have watched on this has anything been said about commentating the 2208 or 2209 stepper motor line.

Is there anything else I should uncomment?
Can I compile the firmware and flash it before installing the Ezabl, will the printer still work? Or would it be better to just flash it during the install process?

You can certainly compile the firmware before getting the EZABL, but I would not flash it to the printer until the EZABL is installed.

What do you mean about the stepper drivers? AFAIK, the 4.2.2 comes with either A4988 or TMC2208, as per this post in the Creality forum: [U]https://forum.creality.com/topic/1118/which-firmware-for-the-ender-3-pro-with-4-2-2-board?lang=en-US[/U]

The might make it easier to understand what I meant, printer section from the configuration.h file

If I read it right, you mean:

//#define V422_TMC2208_DRIVERS //“A” Code on SD Slot
//#define V422_TMC2209_DRIVERS //“B” Code on SD Slot

From this I would say the easiest way would be to look at the control board for an A or B that’s near, or on, the SD Card Slot & uncomment the matching line.

When you word it like that it now makes sense, couldn’t figure out what the SD card slot had to so with it. I have TMC2208 drivers, THANKS
