ATC config

Another challenging work for me, trying to configure ATC.

So, what we have:

8 pockets carousel with geneva mechanism, rotation one way DC motor with relay, index sensor (one pulse revolution, place pocket , disk position sensor (one pulse per pocket), tool presence sensor in the pocket 

actuator/slide for carousel in/out, DC motor with cam gear, one way with one relay, 2 sensors in both ends

power drawbar, DC motor with worm reducer and cam gear, rotates in one direction with one relay, 2 sensors clamp/unclamp

spindle driven by AC servo, have encoder w/index, connected 1:1

LinuxCNC 2.8.4, Axis GUI, Mesa 7i92+7i76

Also I need to add external switch for clamp/unclamp tools, need to work only in manual mode and block when spindle is running.

I've search through forum and found some sample ATC configs, so I think I have an understanding in general terms of what the end result should be. But none of them fit my config exactly. Maybe there is one or a similar config that I missed. I have a very basic knowledge of HAL and G-code, and I think I could fix some suitable config. But I'm afraid my knowledge is not enough to write such a config from scratch. 

Any help would be appreciated.

I think that the setup in sim->axis->vismach->VMC_Toolchange->vmc_index is very close to what you describe.

You would probably need to add in the tool presence detection check. Is that a sensor-per-pocket

Anyway, you can run that config on your machine (it's a graphically simulated config, doesn't operate hardware) and see if it seems to be close.
