I am also having the same issue. DD sent me some more copper tape to try and ground the hose that goes to the CT but no luck. Booooo
Make a jumper from the Festool inlet hose of DD across to outlet hose of DD. This should take care of your shock. Your copper tape may not be in complete contact thus not continuing ground to CT. What hoses are you using? In my setup on a CT33, I am using the boom arm hoses which are anti-static. I've not seen the hoses that come with the DD since I purchased the cyclone only.

I see no reason to not purchase a cyclone, or return one, because of this. You just need to find where the connection is broken and correct. Copper tape does do an excellent job IF you do the same. So, don't give up. I have the Clearvue cyclone and used coper tape that I found in the garden department (repels slugs) to complete the antistatic connection across the cyclone. To make it plug-n-play, I cut a Festool hose connector in half and glued these antistatic parts to the cyclone's input and output and ran copper tape from one to the other, both inside and out. Fixed all my antistatic issues. And all I need do is plug my AS hoses into the Festool hose connector parts that I added and I'm good to go.
Yes, I got a little carried away with the copper tape, but it works.
The collection bucket does not need to be grounded. Only need to have a complete circuit between the tool and the CT.

How are you using 3 hoses? I would think you have the large boom arm hose connecting from CT to inlet of DD; then the 1-1/16" AS hose from DD outlet to tool. If the other DD hose is used, perhaps that is your non-AS link and your circuit is not complete.
tool-->1-1/16" AS hose-->boom arM hose --> DD --> DD hose --> CT all the DD parts are suppose to be static dissipating...not sure if that means antistatic or not. I might try modifying the DD with copper tape as suggested. It's just a piss off since they claim it's antistatic
I would try it without the DD supplied hoses (if possible) since we know the Festool hoses are anti-static. If the shocks are still there, there is an 'open' in the circuit. Then you can check the copper tape. When you elimate the shocks then re-connect your other hoses and if the shocks come back then you know they are the cause.

I was in the middle of typing when I re-read the posts and saw what Corwin said. His system is right to the point and dead on. I am always a little disappointed for my customers, or any n-user for that matter, when they are discouraged by a retailer from purchasing a particular product because of the retailer's own lack of understanding of the setup. Dust/chip extraction is not really designed to be "Plug N Play" no matter how it is advertised, or what the success rate is of the average n-user out there. Proper grounding systems are a matter of woodworking 101 in my opinion.
I personally have never had, or have had a customer complain about the Deputy regarding shock once the prescribed recommendation has been performed.
Well done Corwin, and one can never have too much copper!

I think this is poor product design. Festool does a great job grounding their system and its completely static free...as advertised. This isn't a difficult design feature and I hate that the DD is my weak link. I shouldn't need to modify this product because it should be integrated. Being an engineer I look poorly upon this oversight. You would never see this type of quality/design issue from Festool that's why people love them so much. This is a dead simple setup...there isn't much to understand here. A circuit collects static charge to deliver to the ground. Circuit is broken you get shocked. There is no reason on a Festool vac it shouldn't be plug and play.

I had the same problem and found it to be the short hose supplied. It's not antistatic. I had everything taped like Corwin and was still getting bit. I have a boom on my ct33 and took the short 50mm and put it where the DD short hose is and what do know statics gone. I thought about buying the 50mm AS Festool hose and cut it down, but why should I spend more money!
I ran copper tape along the outside of the DD short hose connected to the short pieces of tape they give you use on the connectors and that does the trick as well. I ran it in one long strip on the outer curve of the hose. Only problem is when i run into it walking around it breaks the tape. I'm going to use some of my copper wire and replace the tape along that hose and it should do the same. it is a great setup, though in hindsight, I would've done a metal one instead of plastic.

Just curious. How hard of a shock is it?

I've never had a shock with my UDD and CT-33.
Two things:
1. Not all copper tape is created equal; some have conductive adhesive and others do not.
2. Consider trying to run a wire directly from one hose to the other, or from hose to extractor or ground, bypassing the offending device entirely. This need not be difficult.

It's a healthy shock (southern California air is very low in moisture) and it depends on the tool I use. The more dust created increases the frequency and intensity of the shocks.
I had Oneida email me a new instruction manual since the one I got was VERY outdated and I did everything they suggested...not like it was difficult.
I tested the anti-static boom arm hose as suggested by others (in place of the DD hose) in this forum and there is still a shock. At this point I know it's the connection between the hoses and the UDD...this still doesn't tell me if the hose supplied by UDD is actually antistatic. I called them a couple days ago and they claim it is (I'm not convinced since I don't read any sort of conductivity in the hose) ...all they sent me is some more copper tape.
I know my machine is grounded because I don't get shocked when I take the UDD out of the equation and I tested my outlet for ground.
Next is wiring a lead from the inlet of the UDD to the outlet or copper tape the vortex cone...something I don't want to do
a) it looks bad
b) this should be inherent in the design.
