Push pull feeder not feeding 8mm pitch parts

[Blowtorch]

Hi Mark

I have a tape loaded in a push pull feeder with 8mm pitch part.  So the feeder needs to be actuated twice - I did set up the feeder accordingly, but it only does the actuation once.  Am I doing something wrong or is there perhaps a bug in the code?

Regards Jorgen

There is a mistake in the video that might explain this, the middle column (↑↓) switch should be enabled:

Thanks Mark will give it a try.

Hi Mark

Forgot to ask:  my top camera is mounted behind the pick up nozzles, so I cannot use vision for the push pull feeder.  Can I still clone, if I set them up in a row, and after the first one is st up 100%, position the nozzle tip at the pick location of the next feeder and clone?

you should be able to clone most of the settings (repeatedly), but Auto Setup and the [+] button won't work.

I guess you need to create the feeder manually, then probably need to set up the three main locations (hole 1, 2, pick) using the nozzle tip. Then set the part. Then you can clone.

Also, please have a look at @crashmatt's clever extension of the Push Pull feeder. Maybe you can create a feeder with a snout long enough to still reach it with the camera?
