NordicCNC's build log

Extremely good point, thanks for letting me know. I will make some changes to the design to allow for fine adjustment.

Don't waste your time, the way you have it now will work fine, that's exactly as I do them. It's simple and works. If I was to make a suggestion it would be to move the switch onto the side, fastened to the ballnut bracket and use the top slot for targets. How you have it now leaves the switch wide open to debris when cutting and if you cut steel or aluminium then could get false triggers when blasted with chips. Also the crap from cutting aluminium with lube can build up on the sensor.

As for the screw heads, I am not sure really. This is something that I can easily fix later if it turns out it is not working as planned. I have access to both lathe and mill so manufacturing a better target, e.g. with a flat surface for the sensor will be possible.

Again exactly as I do them and they work fine, the round head doesn't cause any issues. The only suggestion I'd make is to stiffen up the bracket. The one I use are 3D printed, You can just see it between the mass of pipes and wires in this pic.
