• You wire the stepper the same way you wired your axis steppers:
  • 7i78 connected to 7i76e
    • Read the 7i78 manual to see if you need to flash new firmware
  • Stepper drive/amplifier connected to 7i78
  • Stepper motor connected to drive/amplifier
• Yes, you need the amplifier.  There's no other way to make a stepper motor move.
• Sensors
  • Bench test
    • pocket sensor (triggers once per pocket)
    • home sensor (triggers once per revolution)
    • Optional
      • Power drawbar up (maybe your ATC spindle has some sort of internal sensor?)
      • Power drawbar down
      • ATC slide in (assumes you want to have the ATC mounted on a sliding carriage to get it out of the working area)
      • ATC slide out
  • Real ATC
    • All of the above, plus whatever I mentioned earlier
• Motor homing
  • No, you don't need a sensor on the motor or an encoder.  Even if you buy a closed-loop stepper & drive, they usually don't come with an index on the encoder.
  • The ATC home sensor is all you need to home the system

ok today i´m finished my Prototyp....

I´m included a Geneva Mechanism, Home Sensor, Pocket Sensor
Baseplate now 275mm to get no Problems with my 63mm Facemill...

So next step is to wire and configure my 7i78 with my 7i76e even that works i will wire my Prototyp to the 7i78

if i got this steps than i need much more help to configure this some ngc files....

Hi guys,

I have read this entire thread with much interest. After 7 years I finally bought an ATC spindle and so it's time to pimp our entire machine and linuxCNC. I loved the probe basic screen and functionality and as it seems a Geneva drive is the way to go. 

Now this is new to me, does anyone have a detailed picture of a serious carrousel and picture/video of how it works, where the sensors are placed. I want to build a carrousel with 20 positions in the back of my machine with the carrousel sliding into position. I want to fiddle as little as possible on the software side. So apparently Geneva is the way to go. ( Unless there is already an adaptation of probe basic for linear rack changer) 

Pictures of 3d models would really help me out here to understand how this works and how the tracking of positioning works!!.

Thanks for any and all help!

Hello,
i want also use my ATC and came across to this post.
Is the protoyp running and have you configure wiht pb?

post up pictures of your machine and ATC
