I have a project that calls for me to make some simple cuts in acrylic but there is some engraving that I was going to send it out for but I was curious if anyone has played with this material yet? My concern is spindle speeds and other settings causing melting or causing build up on the bit.
I typed “acrylic” into the forum search and found several topics with good experience documented.

This was a project from last year I cut and carved on a 3/4" acrylic.
Another one from last year…this one was a project for my brother, I made 20 of this and send it down to Brazil
My Brother added the sticker as I could not carve that.

Some really nice projects! Thanks for sharing
how deep did you cut and how many passes
The CVS health was 5mm and 2 passed, 4.5mm 1st pass, 0.5 second pass
The game controller was done with 1 pass at 0.5 mm
thx what was your feed speed i want to try one so 10,0000 spindle at .5 mm depth feed ?
and through all at 4.5 mm ?
Cool result! 
Is the base with the LEDs custom made or did you buy it?
Sorry on the delay to reply, been extremely busy.
@MGSR yes it was at 10000 at .5mm
and for the 4.5mm 1st pass I started at 13000
@kurt My brother made the base himself
OK and thank you for your reply. In the meantime I found a supplier: https://s.click.aliexpress.com/e/cDnuwMVw
Does not look as nice as your one. But seems to be a good starting point.
