Aluminium Extrusion Router Build

[NFryer]

I've now got the inductive limit sensors mounted for the z and y axes. I've got a 2 core CY cable to supply the power and a 4 core CY cable for the signal outputs. I used a couple of 5 way terminal blocks to connect the power leads of each sensor. I also tested a sensor and it seems to work well on aluminium with the output dropping to 0V when it is approximately 4mm away from it.

I've also got the aluminium profile that I need to build the frame from KJN Aluminium Profiles. They provided me a very good customer and the profile seems to be cut very accurately and pretty much bang on square as well.

Finally I had a bit of a puzzling problem with the Y axis ballscrew. As I was moving the Z axis along it would get harder to move towards either end of the travel. After a bit of measuring and checking I found that the 15mm plate the ballnut mount is fastened to was actually about 15.5mm thick which was enough to cause the problem. I took it apart and skimmed 0.5mm from it around the ballnut mount and put it back together. I tried to put the ballscrew back and found annoyingly that I couldn't. Apart it came again to skim the whole area to the side of the mount to allow the ballscrew to slide in.
