Jog cycle/ step doesn't increment, if you type in the inc, it will work.
Jog mode no led's but the button works.
MPG led's x & z not working.
They did work before, tried reloading mach 055,066,067
Other functions work.
Did I turn something off by mistake.

Standard lathe screenset or modified one?
Go to function configs menu and choose reset device select then restart Mach. Choose parallel port in the options and see if things work fine. If they do then seems like its a DSPMC thing, if they dont then possibly your screenset is corrupt.

Deleted my mach3 and re loaded, tested and the functions worked then loaded my XML and DSPMC then they don't work, can't just load XML file and test because I get an error when trying to enable the system.

Attach your xml and I will have a look here.

Here it is.

Seems to work fine here in simulation by using the parallel port option with your profile. What I did was changed the active state of the  E-Stop and Limits so I could take Mach out of reset. I did notice however you had the Jog Control switched off which meant that you could not choose Continuous or Step Jog. Once Jog Control was enabled it worked fine, that may be your problem. You can turn on Jog Control from Manual screen, Jog On button toggles Jog Control between On/Off.

But I can still use the step or continuous or MPG and they work but the LED doesn't come on so I can't see what mode I am in, same for the MPG X &Z.

It would seem it may have something to do with the DSPMC and the way it handles jogging etc.
