There are a handful of useful calculators here:

BELT LENGTH. Calculating the required belt length if you know the pulley diameters and center distance between the them.

"STEPS PER UNIT". Once you get your CNC conversion going, you'll need to enter the appropriate settings into your g-code interpreter software/driver. A popular one is Mach from artofcnc. We've called it the "Steps per unit" calculator.

CUTTING SPEEDS. A common question that many of us ask is "what's the appropriate speed, feed, depth of cut for this operation?". Here's where the cutting speed calculator will help out.

UNIT CONVERSION. Let's not forget one that's used often here. Many (if not all) of the imported machines are metric unit-based. If you're here in the states, you'll often need to convert between the imperial and metric system. The basic conversion factor is 25.40mm = 1 inch.


Looking for mini-mill help and how-tos? How about lathe help and how-tos?

We're prototyping a benchtop CNC vertical mill using the DigiSpeed-XL interface card for Mach, Dart Controls and KB Electronics KBIC/KBMM 90VDC motor controllers, 1.5HP treadmill motor from Surplus Center and a R8-spindle head from the X2 mini-mill - not to mention Gecko servo drives and an entirely closed-loop system. Come take a look!
