The Varnerized ANT CNC is a very small CNC machine with a high resolution for repeatability.

The Varnerized ANT CNC

My machine is a bit different from the stock ANT it was derived from.

All adjustements are open-sourced, STLs and Fusion360 models are available, as is this grbl fork for the ANT to control the spindle ESC with an arduino PWM timer.

My design differs in that:

  • 8MM Rods are used (rather than the 6mm rods used by the ANT)
  • My frame is 100mm wider on the X-Axis.
  • I use an Arduino UNO, rather than an STM based ARM board.
  • I used NEMA 17 stepper motors for all axis.
  • TR8 lead screw with a 140 tooth GT2 belt reduction for the Z axis motion.
  • D2826 1000kv BLDC outrunner, rather than the 'inrunner' models used by the ANT.
  • I have completely redesigned the spoil board & hold downs.
  • Added LED strip lighting to the sides, to illuminate the work area.
