Sounds like you haven't setup your Z correctly for this grid box. To set it: - put an actual part in the grid box - use the nozzle menu to pick the nozzle required for the part you want to feed from that grid box - use XY controls in the motion area of the software and move the mark cam to the first pickup position in the grid box - when you have that position/part centered in the mark cam, use the Z up/down arrow of the head you use to move the nozzle down to the part. Use the Ctrl+Shift to reduce Z step width to something like 100 at first, then 10, then 1 as you get closer to the surface of the part. If you closely inspect the position, you see when the nozzle spring starts to compress. Then you're obviously too close / touching it already and you may want to move back up a little. But for me, so far it worked fine to have the nozzle compress a little (i.e., maybe <10 single steps on the motion control pad) on pickup. - If you want it more accurately, use the vacuum test inside the feeder definition. But I think the pick-up Z doesn't really need to be that exact. The main thing is that the part gets picked up reliably... a few test runs should show. Another value to look at is "SuctionDelay" in the feeder properties. If you have problems picking up the part, increasing this allows more time to build up the vacuum before the nozzle lifts. - Once you're satisfied that the nozzle touches the surface of the part, click the Z button in the "Vacuum Test Settings" area of the feeder properties to take over the current nozzle Z into the feeder configuration. Click OK to exit + save.
