I would be really happy if I could achieve something like this:

I think the specs of this machine are similar to mine.
Yes I will make some new tests with higher feeding speed and report the results. Till now I believe that the most important factor that caused premature tool wear was that I was cutting very deep...
Yes find attached the gerber files.
Regarding the aluminum milling, I think my machine is rigid enough for some light milling. No heavy production of course. Future experiments will show the...
Craig, you are right the results were not perfect. I will consider buying a new spindle. The one you suggested seems really good but it is too expensive for me right now. Do you think this one from...
Hello,
I finished milling the "larger_board". You can see the results in the attached picture.
Settings:
1) Feeding speed = 20mm/min
2) Spindle at 22V (~7333 rpm)
3) Tool: Cheap V-bit...
Hmm interesting... What is the trace width in your boards? I used 8 mil (up) and 10 mil (down) traces respectively.
I use a hot glue gun to attach the board on a larger piece of mdf which is also glued down to the cnc bed.
First results with bed leveling. Here you can see a "test_board" milled with a cheap V-bit 30°/0.1mm. The spindle is running at 26V (~9000 rpm) with less vibrations. Feeding speed remains at...
The first milling I tried was with something like this one:

I had a pretty clean cutout. For the first 15 secs......
First of all I would like to thank all of you for spending your time to help me address this issue.
1) Craig I found your advice really helpful and today I tried for the first time the auto bed...
Hi all,
I own a desktop 6040 CNC router that is made in China. I have managed to make some good test boards I designed for evaluating the capabilities of my setup. However, I noticed that the tool...
