Another newbe with a 3040Z CNC from China :(

As Zasto states, it could be an enable feature too or instead of the charge pump. Under outputs in the config menu of Mach you will see "enable" assign the pin 16, port 1 and see if it works.

The charge pump operates a little differently and is a safety feature.

From my, limited, experience, Chinese drivers and/or BOB's don't have Charge Pump input, mostly only Enable.
Make no mistake between my personality and my attitude.
My personality is who I am.
My attitude depends on who you are.

And we have movement lol, It was enable 1 set to Port 1, Pin 14

I also had to turn on Dir low on the X axis to get the direction right

Next i will try to get some soft stops working

Thanks guys, Im sure i will have other question :)

On a side note i changed the steps per to 200, made a big difference, 400 was noise, My final setup is below

Port 1 (0x378) Matches what I have in system settings
Kernal Speed 25000

Pin Setup
X Axis Step Pin 2, Dir Pin 3 (Dir Low) (Step Low) Step Port 1, Dir Port 1
Y Axis Step Pin 4, Dir Pin 5 (Step Low) Step Port 1, Dir Port 1
Z Axis Step Pin 6, Dir Pin 7 (Step Low) Step Port 1, Dir Port 1
Probe Port1, Pin 15, (Active Low)
Estop Port 1, Pin 10, (Active Low)
Enable Port1, Pin 14

Motor Tuning
X Axis Steps Per 200, Velocity 2000, Acc 200, Step Pulse 3, Dir Pulse 1
Y Axis Steps Per 200, Velocity 2000, Acc 200, Step Pulse 3, Dir Pulse 1
Z Axis Steps Per 200, Velocity 800, Acc 150, Step Pulse 3, Dir Pulse 1

   You are in mm? Correct?

   What is your micro stepping value? If you are running 200 steps, then this is full step. I would most likely run a 10x micro stepping value with 2000 steps per. This would also make your theoretical resolution 10 times better.

Would i only have to change that value in Mach3?  Which 1? the units of measure or the steps per unit?  As you know im a total newb lol, This wont hurt anything will it? No but it will take some recalculation depending on which you change.

Changing the steps per unit due to raising the micro stepping rate (from 1 to 10) will require a change at the BOB too (generally they have either a jumper or a set of DIP switches for configuring this). As long as both are raised to the same level (in Mach and on the board) no retuning of the motors would required (if they are moving the correct distance now).

Changing the unit of measure from mm to inches or vise versa will require a retuning. Not hard just a little tedious. You would need a dial indicator and a 1,2,3 block.

I have been following this thread as I just received a 3040z-dq from an amazon purchase.  I am unable to get my machine to respond at all.  I used your final settings in Mach3, but to no avail.
I get nothing.  I am running an older computer I had with windows xp and a parallel port.  I ran the parallel port test software that indicated it was working. 

Any more suggestions?  Thanks in advance.
