Hi guys and girls.
I have just tried to run a print and the machine and during the pre print heigh calibration the bed moves down instead of up. The print then begins with the bed half way down the machine.
So I tried to run the manual calibration and the same problem occurred, instead of the bed moving up towards the nozzle it just moves down.
Essentially the Z-axis movement has been reversed.
Is this a software or hardware issue, and how is it fixed? I have done several searches and have found nothing on the subject.
