This sounds like a stuck button on your keypad. I would first try just pushing on the Z up button a bunch of times to see if you can "unstick it". Otherwise you can open up the controller and disconnect the ribbon cable to the keypad, and you can still use your machine if you assign keyboard shortcuts to some of the keypad functions. Assuming the repair work done by Plasmacam is under warranty, you could send your controller back and have them replace the keypad. Or you can order a new one for around $100 and install it yourself.

Also - if you can get it "unstuck" and don't want to run the risk of getting it stuck again, you could leave your keypad connected to the controller - and just add a single keyboard shortcut for the Jog Z+ function.

Which advanced software upgrades do you have?

I tried to run the machine with the ribbon cable unplugged the height problem goes away but machine is doing weird things not controllable at all plug the ribbon cable in everything goes back to normal other than the z axis acting up

i have all the basic stuff other than the advanced design software machine control and height control are the basic

You would need Advanced Machine Control in order to have the keyboard shortcut options for the controller keypad functions.
