So i bought an A20M second hand. It powers up the lcd screen turns on with nothing on it, the power supply is reading back 24v. I cannot connect it via usb to computer as it doesnt even know it was plugged in and yes the usb drivers are installed. Is this a Bad control board? or just one with no bootloader/firmware?

Also one of my stepper drivers is pretty warm compared to the other ones even if i move it from one socket to another

Hi, You can try to install the driver manually,
You can refer to this specific method: https://www.geeetech.com/forum/viewtopi ... RlcFtWdCG4
Then see if you can connect to the computer.

If you can connect to the computer, you can download the firmware on the official website: https://www.geeetech.com/download.html?download_id=33
Then flash the firmware.

Hi,If so, you can contact your sales representative to replace the motherboard.
