Melzi board

Hi All,

I would need to solve 2 problems:
- Z axis is moving only 1 direction.
(I succeed to change the direction of the movement, but still the driver is rotating in 1 direction.)
- Bed temperature sensor is indicating 83C degrees with the Repetier Firmware.
(Hot end is working correctly.)

I have attached the working Marlin firmware and the modified Repetier firmware.

Please someone help me to solve these “challenges”.

Check your z endstop. If it moves only in one direction it is normally a triggering z endstop preventing the opposite direction.

Thanks, both things are solved.

Next things:
- The bed is not heating..
(I can turn it on, from the software, but is not heating.)
- X and Y End stops are not working.
(Physically they are working...)

Thanks.

Hi All,

Now it is working....
Modified file is attached.
