Recommended dust boot for your ATC on a OF Z20

Spindles and ATCs PwnCNC ATC System
23

I purchased a SideKick from Adam and I have 2 bodies - 4" when I get my CamVac and 2 1/2 with a Fein Adapter for my Fein.

I also upgraded the 15 X 20 drag chain to 18 X 50 - works well with my PWNCNC ATC. I have 8 low PWNCNC magentic tool holders - but I also have 2 quad tool holders from Adam. Easier to pop them off 4 at a time - so when I want to work on 48" prefin plywood I can then switch over to using the MTC button.

Hey, Garry,

and the dust extraction is satisfactory with the Fein?

25

The fein is adequate but the record power cam vac 3 motor system is way better.

My initial research had the fein cheaper than festool and fein was quieter and more powerful.

26

Hey Garry,

yes the Festool is really expensive. The price of a replacement hose is simply crazy. And not reasonable. But I love the Festool, it’s really great quality.

I don’t know which is better, Fein or Festool. Hauptsache Mittelstand!

Hey Garry,

I think that first I will try to use my Festool CTM Midi that I already own, with its cyclone for the Festool and see how that goes. The Festool CTM Midi has a max. volume flow of 3,700.00 l/min (for US citizen, 1 cfm = 0.028316846592 m³/min) and a max. underpressure of 24,000.00 Pa (for US citizen, 1 psi ≈ 0.895 Pa).

I plan to buy Adam Fenn’s Ugly Dog workshop ATC SIdekick which can come with a Festool dust hose adaptor so things are made easy.

Later, when I will buy the circular frame saw, the planing machine and the router table, I will set up a workshop dust collection system with 100 mm tubes (for US citizen, this is 4"), based on the AF 22 with its 3 kW (for US citizen, this is 4 hp) three-phase 400 V motor (here in the EU, we have 400 V three-phase everywhere in our houses. A single phase of it gives a 230 V outlet).

The Felder AF 22 has an air volume of 3100 m³/h (for US citizen, 1 cfm = 0.028316846592 m³/min) and a max underpressure of 2510 Pa (for US citizen, 1 psi ≈ 0.895 Pa)

By coincidence does somebody know if Adam Fenn’s Ugly Dog workshop ATC SIdekick dust boot also fits the older Onefinity Z-16 assembly with 80 mm spindle mount?

I don’t like the Z-20 assembly because of its much too steep ball screw, that lacks precision and leads to the spindle dropping on power off issue, so that I would need a stepper motor with brake (that is not necessary with the Z-16 assembly)

You should reach out to him and see if he’s confirmed its compatibility. He says its rapid change compatible, so I don’t see why not.

Hey Chris,

of course I am already in contact with him. I observed the creation of the dust boots just like you :slight_smile:

But since he had no Z-16 there he was not sure. But he said it should go.

Furthermore, he offered me to design parts fitting the Z-16 if I provide measurements.

He is such a nice person. And so talented to speak with no script in a video. When I think how many persons you see on YouTube that freely speak and it’s so lengthy and boring. And as a non-native Englisch speaker, I appreciate his good and clear, accent-free english pronounciation.

Just wanted to know if someone still has a Z -16 and uses the Sidekick ATC

For users planning to integrate the PwnCNC 2.2 kW ATC spindle, the Z-20 assembly is the more suitable choice. Its enhanced structural design, increased Z travel, and better compatibility with accessories provide a more robust and flexible setup. While the Z-16 can accommodate the spindle with certain adjustments, the Z-20 offers a more straightforward and reliable integration.

I’m not a fan of the Rapid Change ATC strategy. I have the PWNCNC ATC.
I’m also not a fan of the Z-16 as I don’t believe it can handle the weight of the PWNCNC ATC

I do have the Stepper with brake and love it.

I’m also not a fan of RapidChangeATC. At the moment I own the Mechatron HFS-8022-24-ER20 with manual tool change but since I plan to use the Mechatron ATC-8022-HSK25 later, why not use the ATC-ready dust boot from the beginning. I don’t see the necessity of buying a non-ATC dust boot first (even If Adam’s Big Suck seems to be a great dust boot)

If I replace the Z-16 one day, it will be by a universal Z assembly.

For the time that I intend to use the Onefinity CNC machine, I’m thinking of making a different z axis. @TMToronto already did that with success.

What I don’t like on the Z-20 is the too steep ball screw. Not only it necessitates the use of a stepper motor with brake (to what I would not oppose to, neither to the more massive design), but it has a reduced resolution. Much less steps per travel. Onefinity sells that as “faster”.

That is nonsense. Due to the design with the tubular rails and the cylindric linear bearings, the Onefinity is already the slowest machine on the market (you don’t see that with stepper motors, but one day when you install servos with ten times the speed of a stepper motor), but it’s that in z axis, speed is really no relevant thing. Precision of depth is much more relevant there, so a steeper ball screw is totally counterproductive…

My typical work for this machine consists of removing material depth from large thin wood blanks by tenths of millimeters (backs and sides of guitars and viols) so I’ll prefer the Z-16’s flatter gradient, that has more resolution (more steps per travel).
