New replacement GTM32 pro board not printing right

[blinkdisplay]

Just received and installed a replacement control board on my M201. Tried printing on it and it starts fine but starts doing its own thing after a couple of minutes. I'm linking videos of the issue. One shows printing from the SD card with gcode from Simplify3D the other is tethered with Geeetech's Easyprint software (latest version .19). I've tried reflashing with the same software.
