I will have to probably go that way, adjusting max velocity to what ever it can handle. There is a lot of tweaking I will probably have to do between now and an operating CNC machine. Steep learning curve! At the moment having trouble getting time to put into the project, so I expect to progress slowly at this stage.

I will post significant newbie issues I discover along the way (problems/fixes).
No dought I will be back to pick your brains at some stage with some lame question.

Thanks to all.
