Hi all,
I am completely new to everything related to the CNC world, having said that I have had a machine sitting in their boxes for some time now and decided now is the time to build and have some fun with it. I have followed the instructions by Ooznest and managed to assemble it. I have uploaded the software and the next thing to do is to home the X Y and Z axis. The X and Y home as they should but the Z is supposed to move upwards hit the limit switch then stop. Mine does not go up but goes down, any ideas as to why? I have contacted Ooznest they suggested that I copy all the code and send it to them which I did they came back and said everything was configured as it should be, it must be a faulty Z limit switch. I have replaced the limit switch, but I still have the same issue. Any ideas please.

Regards
Mark
