Thanks - I have tried loading one version (marlin) that was suggested to work but it is worse with that.
The problem is that the firmware on the original one only displayed "RRP" on the printer information screen in repetier so I have no info at all about what specific firmware/version it was from that. It's a bit too vague!
The old board was made by RP3D.com, so I have emailed them to ask if they can clarify exactly what firmware was on it, and where I can download it. Then I can try that on the new one and hopefully get it all sorted out.
