I own the Ender 3 Pro BUT, I have the silent motherboard 32-bit and installed with the firmware: “Ender-3 Pro_HW4.2.7_SW2.0.9.03_SpritExt_H300” because it seems like its the only one meant for the extruder pro kit. It complains that the BL-Touch is not attach to it. I can see it in Octoprint error message and gcode terminal.

With the default firmware on it, it did manage to start the print till its heated to 228°C, but Octoprint couldn’t proceed after the printer heated. It just waited till infinity.

Additionally the Display is not working at all, its beeping and mid beeping a louder beep is repeating every second. Not sure why, but the display claims to support Ender 3 Pro, Ender 3 and Ender 3 v2.

What firmware would be the correct one for the extruder? Should I return the Display?

Silent Mainboard did work with the stock-extruder. It stopped working with Octoprint after replacing the extruder with the new one, but seems to heat and move correctly.

    I’ve installed the sprite pro on my ender 3 max. To get it going I compiled my own firmware and found that TH3D’s firmware was simple and worked well.

    Although it wasn’t long and I added an rpi and installed Klipper.

    For the bltouch, I didn’t really spend time on it. The connector to the included board on the extruder didn’t work - - I ran my own wire directly to the main board. Likely user error, but it’s working so I stopped trying to fix it.

    Hope this helps.
