Almost done, of course I'm missing a D-SUB connector for the back panel... 🙃

This is the size difference between my current probe (right) and my own wireless design. This would give me quite a bit more Z travel which is nice, plus the benefit of not having to plug in the wire every time. Still needs a lot of testing. I'm also just using a makeshift receiver at the moment.

I haven't posted much about the design yet, since I'm still tweaking things. It uses the common 3-leg mechanism for simplicity. Spring loaded contacts then connect it to the main board.

Yes, the goal is a small wireless probe. Small is the important part, since I'm pretty limited in Z travel on my machine.

I made some progress, still far from done, but already doing some repeatability testing. So far I didn't break anything. 🤞

Guess what, it happened again. 🥲

Well infrared meaning the trigger signal is transmitted wirelessly. There are a few on the market that are mainly for bigger milling machines and are way too big and expensive for my use case.
I'm currently using this one from Sorotec but it's already a bit long for my machine and ofc wired.

Don't want to go into too much detail yet, since there is still a lot of work to be done. But the goal is to build a small IR touch probe for my cnc. This top part will provide power to the main pcb via the pogo pins and handle charging via USB port. Hopefully I'll be able to show more soon.🤞

Nice, I've done a few of these over the holidays, very fun! 😊

Good luck on all that comes next, excited to see what you'll be up to at Opulo! ✌️

This tool rack from End-CNC was quite a big inspiration for this: makerworld.com/de/models/11...

It looks so cozy. 😊
