Sorry new to this what is XML? and I will send it.

The xml is the file that holds your config settings, you will find it in the main Mach3 folder. It will be called by the name of the profile you use so if you start Mach have a look down at the bottom right of the main screen and you will see the profile name. Look for the xml with that name, copy it to your desktop and rename to tonymelia.xml then use the additional options button on the reply page to attach.

I think this is the one

Not seeing that problem here so far when using your xml. I am poresuming it is the DROs in Mach and the tool display as well as your motors that are slowing down?

What is the frequency showing on Diagnostics page and also what is Time in Int, also check CPU usage and see if its loading up, especially when things slow down.

CPU is ok but the pulse frequency when running OK is 25,387 but slows to 100 when everything slows. Yes it is the DRO's and the tool display as well as the motors.

Thanks for your help Hood.

Definitely a problem with the computer then, not sure what to suggest apart from maybe try to optimise things, there is a text file on the downloads page detailing some steps you can try.
