Is it possible to get manual control of CNC router after running Mach3 code? I need to move the Z-Axis carriage up after the Mach3 code finished running so that I can remove the work, clean up the CNC router, and set up the CNC router for next Mach3 program.

Yes, if the code is NOT running you can jog the axis up out of the way, however always press the reset after its moved to position as you dont want anything such as pressing a key to start things moving when your hands are in the way.

I tried to use the external numeric keypad usually connected to notebook computers to control my CNC machine. It works if there's no code loaded into Mach3 software. I have to quit the software, run it again, and use the keypad before loading the code into Mach3 software. I put a cork bottle stopper on router bit when I'm setting up my machine or not using my machine. I got a bad cut while setting up my machine a few weeks ago.

Try pressing  the Tab key and using the mouse to activate the on screen buttons.

Hello,
Why not just add the moves at the end of your program?

A simple
G00 Z5
G00 x10 y10 (or wherever you need to move the router bit to)

Add these moves just before the M30 at the end of your program

Another way, hit the TAB key on your keyboard, the virtual jog pendant will appear.

Hope that helps

I'll try pressing the TAB key to call up the virtual jog pendant but will I be able to use the external numeric keypad after clicking on one of the buttons on the virtual jog pendant? I need to look at the bit closely as I lower the bit to the top surface of the wood board.

You should be able to use the keypad all the time(except when code is running) sounds like it is getting disconnected for some reason when code loads. Try reinstalling the keypad and especially try to get drivers from the keypad makers as possibly its loading with generic windows drivers and they are maybe a bit flakey.

I tried to use the keypad after calling up the virtual jog pendant and clicking on one of its buttons but nothing happened. I thought that the keypad doesn't require a device driver to work.

Do the Laptops keys work?

Hi all, hope everyone is doing well!
jeffmorris make sure you are in the program run screen, otherwise your jog buttons will not work.
Some screens will not let you jog.
