First Acrylic Diamond Drag Bit Engraver - Millennium Falcon

Hello!

Here is my first experiment with a Carbide3d MCEtcher Spring Diamond Drag Bit Engraver.
I don’t remember if i used the 90deg or the 120deg bit.
It ended up better than i thought, so i decided to cut the outline later. (Single Flute 1/8 Upcut)
The Source is a detailed outline of the Millennium Falcon (found on Google Image) and i did an Image Trace.

What i Learned:

  • With that much detail, on a small acrylic piece (6"x4"), it took quite a while…

  • Since it was a test, i had choosen the Zero arbitrarily when Engraving. When i later decided to do the Outline cut, i had to Zero on the image detail for the outline cut.
    It is not perfect, but it’s close.

  • Since it was a test, i did not Flip the Image, so the Engraving is on the Front Side, this is usually done on the Back side of the Acrylic.

  • I did not leave enough “Blank” at the bottom (When inserted in the Base), but since it was a learning experience, i am happy.

  • Next time, i will not do “Since is it a test…” :slight_smile:

I then purchased a cheap Led Base from Amazon to test it the Edge lit.
The photos are not that great, but you get the idea…

I’m interested in etching acrylic as well, the results you have look great. What plunge and feed rate settings did you use?

Hello!
Here is what i used. It worked, but don’t know if it is optimal.
Plunge Rage=15.0
Feed Rate=45.0
Stepover=0.008
Full Depth=0.05
Depth par pass=0.025 (Second pass made it pop!)
RPM was ZERO = ROUTER OFF
Note that some Bits allow for Power Engraving, not the ones i used.
When i Zeroed, i made sure the Spring was engaged, and that the Retract Height was high enough to clear and that the Spring was released.
