After the first test, I wanted to do my first special part...
But before, as you have number for tools when you prepare the work, I went to makerworld and found a perfect storage for the tools to be used in a work...

Next was to deal with some headhache : fixing a 300x200 fiber carbon plate on the CNC bed.
It's easy to position and do not pose any issues with the sensor for the Z probe. But fixing will require either custom made fixture or double face tape with strong tack. That's what I opted for. For the story, I consider doing a cut and some holes on this plate to fix it (the rear end of the Carvera Air can be opened to allow a cut on a long plate). At the end, double face tape is easy and convenient.

In the package, I did not find any drill bits (that something I'll have to supply). To overcome this, I considered a hole is a pocket and used for that a 2mm corn bit which will be also used for the countours. And I planned for the Chamfers before the outside countour... I already cut a fiber glass chassis at the fablab, but it was without the Carvera and using another software... But at the end it is not that different. I included tabs, but at the end they were useless since the double face was doing the job perfectly (I did add operations after the part was cut to remove the tabs).

I can say this is a success, hopefully the next work will be as successful...

While I wanted to cut some aluminium, this was defered to later date due to an issue with Makera Cam and the step i'm trying to work with. I reported the issue and will wait for a resolution.

In the meantime, I decided to give a test ride to the 4th axis...

There is some instruction to follow precisely for the sample, otherwise you may rough cut the chuck. I paid attention when launching the gcode.
Image

One thing to note, it's better to note where is the top side of the stock when using 4th axis, as if there is a power failure, it's probably better to be able to recover that position.
Anyway, after removing the mess after the rough cut here is what we have:
Image

And then we proceed to the tool change and the finishing passes...
Image

And here is the final result :

Overally the relief worked well. That's currently the only type of path supported by Makera Cam with the 4th axis. More may come, but no precision yet on their plans. I'm not fully sure yet what would be the best way to create gears, for examples. I'll have to find out...
