Thanks for the link. I will have a look. I guess we all need to start somewhere and appreciate your help here :)

It's in mm, so it was very slow. Yep, have it at F120. I manually changed that just to get it a tad faster. Like your thinking on running it at 10% and then increasing it. I'll give that a go with a much higher feed rate.

Wow, that's about 16.7cm/sec isn't it. Suspect my machine cannot handle anything like that but now appreciate these machines do run a lot faster than I am currently doing so myself.
