Velox CNC router DIY.
What to consider when making your CNC router.
Built small desktops, plasma, to 16x 5 foot machines.
Frame of the machine
Steppers versus servo.
Lead screw over Ballscrews
Rails over shafts
Stepper motors have a particular rpm where the torque is strong. You want to know this because this information will assist with building a cnc that is less likely to lose steps.
.100 pitch with one start is good with using a 280 oz/in stepper motor. Good cutting rate is 40-100 IPM using gecko drives.
I have heard of lower priced drivers losing steps after 30 IPM.
Nema 23 versus Nema 34
Feed rate - How fast do you have to cut?
Hold down clamps
Wood and t slots
Ring on tools
