Pins can get sticky-they clog  with dust from paper tapes. A fatal mistake is to use oil to lubricate, as this forms a sticky mess with  paper dust.
Assuming the solenoids are working, you probably nee to strip down and clean, with a non-oily cleaner

RV Hardware / Feeder indexing pin
« Last post by Mpbrock on April 07, 2019, 07:58:11 PM »
Hi

I’ve got a 10x8 feeder grey type where the index pins aren’t moving in the Z direction, is this a fault anyone’s seen before? They move back as forth in x but don’t lift up to engage the tape (I’ve tried all 10 - none lift up)

Thanks in advance

For Sale/Wanted, Suppliers / Selling my EMC chamber

Pushing the remit of this group a bit - I'll delete if unworthy...

I'm (mostly) giving up the consulting game and moving in with a customer. I'll keep most of the toys at home, but the (biggest) EMC chamber is just a bit luxurious for home use, so should probably go to a new owner.

Cambridge (the UK one), buyer collects, and a plucked-out-the-air £3500.

If it doesn't sell - then I'll convert it into a few screened rooms and a smaller chamber that I've got enough ferrite tiles to cover.

I carried an RV4s up a loft ladder, one arm holding the weight and one hanging onto the steps.. ( I wouldn't reccomend it though !)
the cabinet was a different issue,
Mine had to be dismantled to fit through the door !

The standard models are 25mm ish high I think. I used these on the base plate of the machine. I actually did some pcb holders that I printed off. They had 6mm high magnets in them and were about 20mm high. I placed a couple of components on a board near a holder but without tape or paste on the board and the components moved. These parts have such little mass, they can be affected.

So Mike is right, you do have to be careful.

I guess its probably? ok because the magnets are at the base and the tapes ~22mm above the magnet? Did you have to tweak the height of the feeder Trev - not sure how much Z-travel the RV*S actually has (yet)...

Be careful using magnets - most parts are magnetic and can tombstone in passive feeders if there is a strong magnet underneath.
magnets from small speakers ar ideal as they are usually well shielded

Hi

North-west UK, and yep bought off eBay yesterday - lots of research until it arrives.

Have experience with much larger machines (iPulses) and Juki's so not new to the PnP game, although I've never a none-XY gantry based setup, so going to be interesting.
