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.

Thanks for the suggestion. I will check the feasibility of moving the sensor to the ballnut bracket! I was also thinking that for fine adjustment with this simple setup, one could use a dial indicator when adjusting the target.

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.

Looks good.I think I could make a stiffer bracket out of aluminium without any problems. That X-axis ballnut bracket looks interesting. If I am not mistaken I would think you are using a rotating ballnut. Any chance I could get a closer look at that?
