this is my working marlin firmware. if Z motor not working with this firm, you should check electronic side, ramps, cabling, power supply, etc ...

thank you is it ok to have two endstops max height and min?

every time I try to upload marlin to the board it just hangs for ever.. lost sorry

try sprinter. that's what I use. Everything runs smooth.
