    All good stuff. I am learning from your build. Thanks.

    Pleasure. I'm impressed you can read and understand my frenchglish.
    I'll see if I can get future data on that probe slightly less compressed resolution-wise next time, or do my best to explain why it is not at least (my bad).

    Why not a 'perfect' trilobe? Two main reasons:
    1) approximations and finite steps in the theoretical analysis (you are not looking for an absolutely perfect solution)
    2) micron-level differences in sizes and positions in the mechanical world (plus surface irregularities)

    "The difference between theory and practice is greater in practice than in theory."

    By worlds-size the best tool in the shop. Ultra compact, programmable, accurate and rather stable. Like it, a lot.
    Plugged in bluetooth comm with a 4.2V lipo just for the kick of it, works great. Thinking about integrating an AM/FM radio with a sml speaker next

    That is a thing of beauty, Mecanix. Impressively quick build time too - usually this kind of project takes me months to tickle along in the background. Well done and thanks for sharing!

    Great Work Mecanix and ( I must add zone associates).
    Projects like this usually take months to complete and at times never get done. I am very impressed with the dept of research you and the associates have put into this project. If you are going to market the plans or even a finished device shoot me a PM. I think I want to be in line for one.
    I watched such a unit being built as a "reasonably priced unit" but in the end, I guess the creator and myself had a very different idea what reasonable is! He built a beautiful unit but after spending months watching, the final product was not within my "hobby" means. But I'm always looking to upgrade my tooling and very much enjoyed your build.
    Thanks for posting and very impressed.

    Knew you'd fancy seeing our new probe Thanks



    @dharmic, @Bill, thanks guys. Glad to hear you liked the built as much as I did. They are good fun to make after-all so time flies when you dive into this. Happy I've made it before self-deadline (Oct 1st) which is about the time we plan on digitizing a few parts with the probe you see on the pic above.

    Bill, the one you are looking at isn't all cheap... something like 50-60 hrs went into this all together I'm sure (roughly), so not a cheap one-off probe at all lol. Possibly what happened with the one you previously got... that builder must have passed the rate/hrs to you guys which is a bit unfair :/ I actually do plan on running a small batch and already have 6 standby; 3 of those going to the same guy (I think he plans on crashing two lol). I'll add you in if you want. Think in the line of $125/135 machined/anodized/assembled/cabling/packaged. Something like that. Just can't think of anything that could skyrocket the price above that (AM/FM Radio?).

    Next Step: Running this probe 25,000+ times on my scans here and watching how it performs. Ultimate test, I'll report back. If all goes well this can ship out to you during Now'19.

    Special thanks to Bob(Max), Dharmic, Roger, Britt, jkkmobile and everybody else who've contributed brilliant ideas, support and helped along the built! Cool team, great forum. Very grateful guys, thanks.

    I'll keep this thread up to date as often as I can guys.

    Just getting back to this forum and I am so happy that you have completed the probe. Fabulous looking device. I am dying to see a video of it in action.

    Yea, done that! Struggling to select a good 3rd party Digi Point Cloud Software lately, although my CAD can interface both modbus or OPC (mechatronics) so I might just port this over that.
    3D probe is very much live, ultra sensitive also, fairly happy with the end result. ps: don't ask me to make vids man I really sux at this stuff... a quality camera is possibly what I need maybe lol
    Anyway, here's one of 14sec. https://www.dailymotion.com/video/x7lsi5b

    Including two screenshots for you also. Sure you'd like to see how things look like under the hood

    Thanks for the update Mecanix!
    Yes, put me in for 2 of therm if available. I always want a spare on the shelf to make sure the primary is never damaged. Seems I only kill those instrument that I only have 1 available.
    Many thanks again.
