Plywood CNC kit repeatability testing. 

Hi. Thank you. That's correct, the machines use roller chain on the X & Y axis. The chain runs along the outside of the X rails and the rear of the Y rail. The Y might be hard to see but you should spot the X easily. Best example is seen here: Plywood & steel 3 axis CNC router kit at 4.29 There is more to building a CNC table than people realise. Although anyone can put some parts together, there's a lot more involved - but you only find out about this during the build, when you get stuck.....

Hello, I've been looking at your videos. The machines you have built are fantastic. I understand that you are using linear chain for the drive mechanism. Do you mind me asking where the linear chain is? I can see it in any video...?
