hey silyavski and eddycurrent. That is an absolute load of helpful information. I'm really overwhelmed with the amount of effort that you have put into helping me.

clearly you are a real asset to this forum and I too hope to give a little back once I have gotten a hang of all this.

So much to go on and I'm now going to order some more cutters from the eBay link you suggested. Glad you mentioned using the smaller guage cutters. Especially as I reckon I may break a good few with practice!

Going to have a good read up on mach3 now. But seriously I do really appreciate all the help you have given.

Cheers. andy
