A new Centroid CNC Kinematic Machine Tool Touch Probe is now available.

Wow sold out in 24 hours. I think maybe making the probing routines available in the licence upgrade might have helped with the brisk sales. It certainly made me upgrade sooner than planned.

Is there any reason why the new probe could not be used on the All in 1 DC board? It would be nice to able to use the probe on more than 1 type of control board.

The KP-3 was designed with flying lead cables to keep the costs low and make it easy for Acorn users to connect it.
But yes, you could use it with All in One DC provided you get the CPC connector and the mating header cable (about $50 from Centroid). (Centroid is considering a deluxe version of the KP-3, but nothing finalized yet and due to the current virus situation, it has made things more difficult for Centroid, but they are TRYING.

There is a small circuit board under the heatshrink tubing of the current flying lead cable version. The purpose of that tiny board is to invert the NC output to NO. This is required to maintain compatibility for use with Centroid controls (all of them).

Hopefully Centroid will get more built and back in stock soon. The KP-3 is modeled after the DP-4. It is robust in design. Mechnically it is VERY similar.
I think users will appreciate it over inexpensive kinematic probes available on the market.

I looked at the hookup schematic for the probe. It appears the probe uses the same inputs that the basic Acorn schematics recommend for a tool touch off device. If one had a probe and a tool touch off device, do you wire them in parallel, move the touch off to another set of inputs, install a switch, or do something else entirely?

Please see attached schematic (both devices are Normally Open)

In a nutshell, there must be a separate DETECT for each probe. Probe tripped input is shared

Marty, thanks.

Can we place orders for the KP-3 and get on a waiting list, even though they're listed as out of stock, or must we wait for new stock?

yes, the add to cart button was left active on the KP-3 webpage just for this reason, they are back in stock! thanks, K

KP-3 draft users manual attached for comment.

Maybe I missed it, but there doesn't seem to be any instruction on setting the tool length of the probe in the manual, only the pre-travel diameter. I assume you set tool height just as with any other tool, but is there any pre-travel movement to establish? It appears that the stylus will move .25 in the Z+ direction. Part of this has to be utilized before the probe is tripped, correct?

[cnckeith]

set the probe tool length in the tool library just like any other tool. no pretravel needed for Z height offset for the KP3, the KP-3 triggers in Z with very very small movement much smaller than the accuracy of the machine, so no need to try to compensate for that tiny bit of Z movement required to trigger the probe in Z.

The KP-3 manual has been released...link is located on the KP-3 web page along with a new setup video by Marty, check it out here..

Thanks. I just received notification that the Brown Truck just dropped mine off at home!
