Tossing my hat into the ring of DIY Cafelat Robot gauge brackets
The factory-supplied gauge bracket faces my gut when pulling a shot, so it is relatively useless.
I am aware of gauge brackets by these individuals/companies that all aim to mount the gauge near the top of the machine:
The bracket:

- Naked Portafilter
- Alex Michael Rueda
- Santiago Luz
- Chris James
- Tamás Tóth
- Arno Nühm
- Go Ahead
- Cheng Chuan Hsieh
The bracket:
- Is provided as a free (configurable) CAD download for 3D printing.
- Uses the original hardware (nothing else needed).
- Has a configurable viewing angle from straight up to 25 degrees.
- Resists rotation with a foot that engages the body.
- Resists rotation because the tube connector is at the same height as the connecting pin.
- It is arguable ugly.
- Deviates from the "pure" factory design.
- Requires a 3D printer (or payment to a 3D print shop like MakeXYZ.com).
- Requires effort to remove the original fittings from the original bracket (permanant Loctite was used).
- Is yet another lame attempt in the already overcrowded world of these things

I watched the video, hoping to understand how one might remove the gauge from the bracket. The video made me feel like it was 9am at work in a conference room. No offense intended! Anyway, I didn't understand the part about removing the gauge from its guts. You just clicked a menu to do it. How do you do it in real life? Does it just unscrew by hand or what?
I'm okay with the front mounted gauge since I don't pull shots from the above position. So I'm just curious. But for people who want to do this, removing that gauge is the crux. You don't want to break it.

Yeah, clicking in CAD to remove a part is so much easier than real life... except I even struggled with that!jpender wrote:I watched the video, hoping to understand how one might remove the gauge from the bracket.
Referring to the picture below...
- To remove the Gauge from the Brass Adapter: Hand-turn it counter-clockwise. Easy.
- To remove the Bracket from the Robot Arm: Use a tiny Allen wrench to loosen the two set screws in back (not shown). Easy.
- To remove the Legris 90 degree fitting from the Coupler: Use two open-end wrenches. Easy.
- To remove the filter (not shown) from inside the Coupler: Tip and shake the coupler and it will fall out. Easy.
The Brass Adapter is threaded into the Coupler with what may be permanent Loctite. The Bracket is sandwiched inbetween.
The method I used was:
- Clamp the Bracket in a vise.
- Jamb/twist a flat screwdriver between a flat side of the Brass Adapter and the inside of the Bracket, to keep the Brass Adapter from spinning.
- Use an open end wrench to loosen the Coupler.
Does that help?
Thanks. That's the one part I have never disassembled. It's shown as a single piece in the Cafelat Robot user manual.John Michael Hauck wrote:To remove the Gauge from the Brass Adapter: Hand-turn it counter-clockwise. Easy.
Trying it just now...
The gauge is smooth and slippery to my fingers and won't turn. I tried to grip it with a piece of rubber but it's still too slippery. It won't budge. Perhaps I'm doing something wrong.
I wonder if Cafelat used Loctite between the gauge and brass fitting on your unit.

I just bend over the Robot pressing the levers down and face the dial on the opposite side...

Per the Cafelat store when ordering a replacement gauge,"Please note the gauge has been bonded into the bracket and the fitting has been threadlocked into place."
So I would assume that is the problem on why yours won't come undone.

Yet the OP had no trouble unscrewing his.
My Robot was purchased in 2019. So if they bonded them back then and they're bonding them now then either they weren't doing it when his was manufactured or they just forgot. Or maybe his Robot is even older than mine.
Makes me wonder what percentage of Robots will work with the OP's design.

Referring back to the terms I introduced in my previous picture (for better or worse), if the Gauge is threadlocked to the Brass Adapter, the proposed 3D printed part will work fine. That is, the Gauge and Brass Adapter may remain bonded throughout the modification process.Blaine wrote:Per the Cafelat store when ordering a replacement gauge,"Please note the gauge has been bonded into the bracket and the fitting has been threadlocked into place."

Where the difficulty arises is removing the Coupler from the Brass Aadapter. That is because the Coupler and the Brass Adapter sandwich the arm-mounted Bracket. That is where I had difficulty (on the single machine I have ever worked on).
In any case, before starting down this path, it might make sense to ensure you can dissassemble the arm-mounted Bracket as the first step.
Some of the other solutions I have found online keep the whole gauge assembly in tact.
They are ugly though.John Michael Hauck wrote:Some of the other solutions I have found online keep the whole gauge assembly in tact.
