https://www.youtube.com/watch?v=EaxnEKCUREk and playlist 18uilding a casting mold for the bridge of the CNC machine with laminated boards; Threaded inserts for the linear guides, ballscrews, stepper mounting and the holes for the connection to the first part, the base. A granite board underneath provides the flatness. Inside edges are sealed with silicon and the inner faces are coated with separating wax. Volume ca: 75 liter All ready for the mineral cast with epoxy and rock and gravel… https://youtu.be/yglTpUNokUU

Kronosrobotics
http://www.kronosrobotics.com/krmx02 Large CNC nema23, a steel and aluminium combination. Provides book($90) and private forum, costs around $3500 and week labor and incorporates Momus cnc bearing design. Linked from http://www.cncrouterparts.com/krmx02-parts-bundle-p-153.html (moved here from Cnc electronics). This 212 page book describes step by step how to build your very own heavy duty rack and pinion CNC router. The author breaks the process down into individual chapters. Each chapter includes its own bill of materials, list of tools needed. In addition both time and cost estimates are also at the start of each chapter. Discussion forum at http://www.cnczone.com/forums/kronos-robotics/, http://www.myheap.com/cnc-stuff/krmx01-cnc-router.html. Amazon build guide http://www.amazon.com/Building-KRMx01-CNC-Illustrated-Precision/dp/1938687108. Much of the aluminium frame can be replaced with steel.

See Cnc_electronics for similar setup, it strengthens the aluminium extrusion. http://www.joescnc.com/ from kit, the rack and pinion design part was lifted it seems from http://www.cncrouterparts.com/parts-list-for-acme-axis-p-58.html

In Part 1, we set up the Arduino & GRBL shield. Now, let's use inexpensive linear motion hardware (links below!) to assemble the bearings, rods and steppers into a functional CNC machine! In this video, we look at the CAD model of the machine, discuss basic design philosophy, test it's accuracy (amazing results!), then do the final GRBL set up so that we can export CAM G-Code to use on the machine! We just added a Part 3 with a Z-axis upgrade! Check it out at https://youtu.be/gzLYNSQEPDk ! CAD Model (SolidWorks) available for download at http://bit.ly/1LaLPhv (For Patreon Supporters)
