3d touch probe

Thanks mate. Looks like I'll go for that one

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?

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.

Best thing I bought for my mill, improved my accuracy massively, although it simply shows how much backlash I have on the axes.....

I got my mill conversion down to 0.03mm with compensation turned off.
Not great and even that took some doing to get to that stage.

My Renishaw has a cable, so I have to plug it in each time I need to set something up on my machine. That's a PITA but it allows excellent setup which is more accurate and repeatable than a mechanical edge finder or (Haimer clone) 3D indicator. Overall I can't complain!

Another solution would be an add-on wireless adaptor like the Xoomspeed product https://shop.xoomspeed.com/products/...11877005295663

Bear in mind you need a probe in addition to the wireless kit. He developed this so that he could use his probe in a Tormach ATC.

Nice - very clear write-up.

Thanks, Alan

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.
