Z Axis not moving upwards
I'm new to 3D printing and I've recently finished building my printer (Acrylic 3DCSTAR P802-MHS 3D Printer) and have been trying to fix it's problems, this one I could not figure out, so maybe you guys can help me out!
The problem is the Z axis does not move upwards both in manual control and while printing. In the Manual control it moves downwards no matter if I push the "up" or "down" button. X- an y-axis work correctly.
Do you have a solution to my Problem?
