Hello all,
I am pretty sure that you all are tired of us Newbie asking the same questions. I did look through the posts and still cant find answers.
If I posted this in the wrong forum please move.
Newbie with a New 3040 Chinese CNC from Ebay. Hooked to a Windows 7 Desktop, installed software, yadda yadda. Unable to get it cut/engrave. Dude in China says Windows XP. Hook to a XP box. Somewhat better but its still not doing what it should.
One thing I noticed, I zero'd Z on the top of material (3/4" thick piece of Pecan, about 8" wide and 10" Long). Try to use example Gcode and the bit rises above the material. the DRO for Z shows like -1.0 (or similar). In my mind - would be down not up. Is there something that I missed when setting this up using the Chinese Manual?
Please help.

Hi Mike,
Welcome to the forum.
You should be able to move the Z axis with the keyboard Page Up / Page Down keys.
Page Up increases the Z axis DRO reading and moves the tool away from the work.
Page Down reduces the Z axis DRO reading and moves the tool towards the work.
If this is not the case then Config / Ports & Pins / Motor Outputs - change the state of the 'Dir Low Active' box for the Z axis.
Tweakie.

when you setup your ports and pins z set to active low just click on and set active high to change the direction
