Last Monday, I received a C86ACCP board for my Centroicnc Acorn Board and some Teknic ClearPath servos. Unfortunately, the board came without instructions. I visited their website and downloaded several documents, a report file that the Acorn can use, and watched three short videos. The documentation seemed to be for another version of the board. The report file was for an older version of Centroid's CNC12 software. The videos helped but were incomplete. I fiddled for about an hour and got the board working. Then I opened a support ticket with CNC4PC. I listed the issues that I had with their documentation and listed the 14 steps that I used to wire and test their board. The next day I received a response from Arturo. He apologized for the out-of-date documentation. He answered all my questions and told me that they would have up-to-date documentation on the website as soon as possible. The next day, I checked their website. The new documentation was already posted, including a report file for the Acorn that works with current software.

That was outstanding support! The board works very well with the Acorn and ClearPath servos. It allows me to use Teknic supplied data cables without modification. Hookup is simple. I changed the jumpers from HARD to SOFT. I changed the jumper for Acorn Enable from OFF to ON. I connected 24vdc to power the board. I connected relay COMMON to GND and relay N/O to the DriveOk input on the Acorn. That's it.

Before using the board, I had to cut off one end of each Teknic data cable, install ferrules to each of the 8 conductor wires in each cable, install 8 DIN rail terminal blocks per servo, and 8 connector wires with ferrules on the ends of each connector wire.

I ordered a 2nd C86ACCP board. It arrived yesterday. This time, because of Arturo's help, I had the board installed in a matter of minutes.

If you use ClearPath servos with an Acorn board, buy a C86ACCP board. It's an excellent product.
