No updates for a while, but I learned a lot about the CAM Module in Fusion 360. I watched many youtube video, some good and a lot of bad ones.

Let´s get to the first problems. The T-Nut table is made of hollow 16mm extrusion profiles, not one plate. Those are mounted with M4 screws only on the front and the back of the mill frame.
There is no additional support for those over the whole distance from front to back, about 700mm.
Not really a ridget construction.

Meanwhile, I ordered some carbide 2 flute mills on Amazon. According to some other bloggers and YouTubers opinion, they are best suited for aluminum as the aluminum does not stick in the flutes.

Then I saw a video from CNC Kitchen in which Stefan used an attachment from GoCNC for his CNC router that did come really close to the idea that I had in my mind for a while.
Basically, it is a tray that has some T-Nut profiles glued in and allows you to mill with coolant and have a closed loop without the coolant running all over your router.
The "Liquimaster Pro" is a metal tray (345/530/45 mm) with the T-Nut profiles, a small pump for room fountains, a hose with a nozzle and you get a bottle of coolant.
As this looked good in the video I ordered it for 235,19€ including shipping for 12,90€(usually you can send big and heavy parcels here for around 6€!).

Well, I am not so sure what is "Pro" about this thing. The painted tray need to be clamped on the existing T-nut table with M4 screws. The little pump is also glued to the tray, not sure why.
There is a piece of foam that is put on the hose that sucks in the coolant from the tray, to prevent chips from being sucked into the pump. Well, that does not work at all.
Like in Stefan's video the nozzle was clogged with chips after a short time.
Also, there is nothing to mount the nozzle, so I used a piece of art made out of cable ties. I planned to 3D print something for that.

Maybe I should also mention that I asked per email how the profiles are mounted to the tray before I ordered. The answer was with "special" glue!

So I installed the "Liquimaster Pro" and prepared to mill my first part. The hose from the pump pushed the foam pice up every few minutes. So I had to put something on it.
And the coolant did not come out in a constant flow. I added some Water to the coolant to increase the volume to get a constant flow on the workpiece.

So far I looked promising:

Here you can see the cheap clamps and how they bent. Under the workpiece, I had a piece of thin wood as I did not want to mill in the profiles.

Here I already removed the nozzle from the hose as it was clogged with chips.

Until then I was really amazed that I spent the money to good use and made already plans in my head how to design a 3D printed mount for the nozzle. As this was my first part and also in aluminum I milled very slow with slow feed rates and 0.2mm layers.
As this seemed to take forever I left the mill to do something else in the meantime.
But when I came back to ma garage, the Liquimaster Pro was already torn into pieces.

What happened? As the mill bit was milling thru the bottom of the part, the thin remains caught on the flutes and lifted the part up. But it was clamped down? Yes, but the "special" glue did not withstand the force and both profiles came loose.
The bit milled a little in one of the profiles, took some bites out of the workpiece and then finally broke.
The small pump did not work anymore as well. I guess some chips are in the pump, and as it is glued to the tray I did not found an easy way to clean it.

Here are some picture from the workpiece:

Here you can see the big bites the mill bit took out of the workpiece and bent the edge.


The "special" glue is just some sparly attached silikon:

I guess I might be made some mistakes with the milling parameters for sure. But the "liquimaster Pro" is a piece of toy that does not hold up to the forces when milling metal and something goes wrong.
The whole construction is a joke and charing more than 200€ is extreme.
