Not sure what to do...

[irving2008]

Thanks I appreciate the Comments!
I reckon for my first machine I might take EddyCurrents advice and go for the 3040 off ebay, though the 0.05mm repeatability is 25% of my target 0.2mm accuracy which is a bit worrying, but I hope it will be good to get my started?

Many thanks again
Dom

No, it's 4 times more accurate than your target

But don't believe everything you read on eBay either..... suggest you trawl threads here for 3040 owners and ask what they actually get...
