Lead CNC Machine – 1500 x 1000 (includes 4 x High Torque Motors)


SKU: US-KIT-LEADCNC-15X10 Category: Tags: , ,



This kit includes 4 x High Torque NEMA 23 Stepper Motors!!!

This is the Maker Store 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 Maker Store 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.
