After browsing many websites in search of CNC machines and their construction it soon became apparent that every machine I saw had been constructed quite differently. My conclusion to this, is that we all build within our range of skills and use the materials that we already have to hand or which are readily obtainable. My CNC machine falls into this category exactly - It is probably the best I can achieve within my abilities and with the materials I can obtain. For my construction, I chose to make a welded steel frame using fully supported linear rails and ball screws for the X and Y axis with round linear rails and a trapezoid lead screw being used for the Z axis, all direct driven with bi-polar stepper motors. My exploits into the world of CNC have been and still are great fun and as a hobby it can be extremely rewarding, I recommend it to anyone seeking a challenge.
