My name is Rusty. I am new here and new to CNC. I am trying to find some small bits. Most of the small bits I see online are metric. I was wanting to know if I could use a 1.5 mm bit but tell the software it is 1/16 inch? Would that be enough of a difference to cause problems? I will be using vcarve software. Thanks for your help.

Welcome to the forum, Rusty! Add your first name to your profile to clear the N/a in the side panel. Add your location, as well.

I don's use Vectric products but you should be able to define the actual tool diameter in your tool library, whether it's Metric or Imperial.

Which CNC do you have? We like photos so show us your shop, tools, projects, etc. whenever you're ready.

Welcome. You can find lots of Imperial (i.e. inch) bits in lots of places. Amazon has tons and there are a number of companies that specialize in router bits (and CNC router bits, too). Prices are all over the map from cheap (and low quality) Chinese bits to very high quality and expensive American bits.

Always Always plug in the actual bit size. Even really small differences will mess up your cuts. It doesn't matter if it's mm or inch - 6.35 mm is the same as 0.25" for example - just enter the correct number.

One warning about VCarve - if you switch between mm and inch, they don't convert the values like a lot of other applications. So if you have 0.25" and you change to mm, you'll have 0.25 mm. You'll have to manually change the numbers - to 6.35 mm for the example.

Thanks for the welcome and info. I didn’t think it would work being off a little. I don’t have my machine yet, it is on order. I am getting the Piranha XL and it comes with free laser and forth axis. It will cut 12 by 24. I have been woodworking for years and am looking forward to getting started with the CNC.

Rusty Welcome to the forum. I'm also new to cnc and in my quest for bits I have found that e-bay and also amazon are the place to go for bits. I have purchased 1/16 bits from both. E-bay has alot of china made and also domestic as does Amazon,

Ok dumb question time. My machine will have x axis of 12 inches and y axis of 24 inches. In the software the x axis is longer than y and easier to work that way. Should I work in the software to match the machine or swap the x and y cables on the machine to make x 24 inches?
