20%OFF LEAD CNC Router Machine Full Kit



This is the BULK-MAN 3D Kit of the Open Source Lead CNC Machine.

The Lead CNC Machine was originally designed by Mark Carew and the design is licensed under CC – Attribution – CC BY. It is a super strong, accurate and easy to assemble CNC machine.
  • Based on C-Beam, V-Slot, Xtreme Solid V-Wheels and TR8x8(P2) Leadscrews it is strong, accurate and reliable.
  • It has been designed to accurately cut foams, woods, plastics and aluminium to 0.05-0.10mm accuracy or better.
  • Functional engineering parts, toys, signs or anything else that can be imagined, can be made on the Lead CNC Machine.
  • The BULK-MAN 3D Kit has a couple of small differences from the design published by Mark Carew. Most notably are the use of Black Corner Connectors in place of Cast Brackets in order to increase rigidity.
The LEAD CNC Full Kit is a self-assembly kit and comes with everything needed for building your CNC Machine. Other parts that are needed for you to perform your ‘first cut’ are:
  • Baseboard
  • Endmills
  • Power cord and
  • Software

The 1.5kW Air,  1.5kW Water,  2.2KW Air  or  2.2kW Water Cooled Spindle Bundle contains all the hardware for mounting a the Spindle on your Work-Bee or other CNC machine.
The Cable Drag Chain bundle contains all the hardware for mounting Cable Drag Chains on your Work-Bee, Ox CNC or other CNC machine to help with cable management.

Our 6 CNC Controller Options are broken into 2 software categories: GRBL and Mach3/DrufelCNC.

These are the different software programs that are used to control the CNC Machine and send G-Code.

Our professional recommendation is the xPRO V5 CNC Controller which is the most advanced GRBL CNC Controller of its class in the world. It has 6A silent stepper drivers, WiFi and off-line options, and 4x faster than our other controllers.

For more information about the different controller options, please for more details!
