Delta Printer 3KU issues

Hello,
So I just finished building my printer that I got from [Aliexpress]. It is all assembled but I seem to have a problem with the movement of the axes. Via Repetier host which was recommended by the seller of the printer, I try to move the in any direction, and they all go the same direction. Eventually hitting the metal bar without stopping. I have tried different firmwares, and they all produce the same result. This includes trying to use the extruder.

Any Suggests?

get yourself a fresh marlin version, who knows how the stock firmware was configured.

2nd before you move you need to home that is when all carriages go up. and if they ram into the frame your endstops are not configured correctly.

Okay, fixed the issue. The Z motor was hooked up incorrectly.
