You have to be careful with that now.Quote:

That is one benefit of the eBay Global Shipping Program. You know exactly what it'll cost before you buy it.
Thats the issue. It doesn't state what import duties would be, just "may be subject to custo.s duties depending on value"
>>> I got an old Renishaw MP1s for something like £160 and fitted a cable to it (originally wireless).
Muzzer - could you say a bit more about this please. Off-the-shelf cable? Is the pin-out fairly obvious? You had an 'MI5 interface unit' already or you managed without this somehow?

Please see some our variants.
PLL005-G2(G3) and PLL006.

It's dead simple. The connector is revealed when you remove the inductive pickup head, at which point you discover it's just an old fashioned 5-pin DIN plug, just like we used to use on audio equipment. The circuit is just a normally closed (NC) contact that opens when the tip is displaced. It's a doddle to reconnect. In my case I also fitted a loopback wire so that my (Centroid) controller could see if the probe was present and thus prevent heroic / expensive moves if it was.Quote:

Nice - very clear write-up.
Thanks, Alan
I got my mill conversion down to 0.03mm with compensation turned off.Quote:

Hi
I have been considering 3d probes myself, thinking of getting one for my new machine when its ready. I will have ATC spindle so should be able to leave the probe in a toolholder all the time.
Looked at a the ones linked above which look good but was thinking wireless would be a better option I thoght this one looks ok and not silly expensive

Also this one which is cheap and has a magnetic connector which might be good. https://topcom.cz/dig3dlpm/DIG3D-LP-M-p262128333
I guess you just run the wire near the spindle and plug it in each time you use the probe.
Do you guys who have probes just have them on a loose wire or a quick connector?
Makes me think it would be great to use some kind of Lidar system on the machine for recognizing the material instantly, saw a demo of ipads with it built in for scanning rooms in 3d.

Yes, that's pretty good in reality. There are buckets of BS on forums and Pootube where armchair machinists claim to "hold tenths" or better on their machines.
My Shizuoka was a very good quality machine when it was made, with top end HSK ballscrews and bearings and cost more than an average house yet they "only" claimed accuracy of 0.01mm. Clearly with the passage of time and without a professional to set it up, I won't get close to that. In practice I'd probably be happy with 0.05mm and TBH, I don't expect there are many things I'd make that would require much better precision.
Part of the skill of designing stuff is taking into account the facilities at your disposal. I'm not expecting to be a pub legend any lunchtime soon!
