Oh nice, I did not see that suppress speckle option! Last time I got a bunch of specks I spent a half hour in makercam deleting them all out. I will definitely have to mess around with more of the options next time I do coasters.

Yes, all of mine were done using follow path operation. All of them except the Targaryen one were done with a 1/32" dremel engraving bit. The Targaryen one was done with a diamond point dremel engraving bit. I'm not sure what the tip size actually is, but the lines it gives are much much finer. Only problem using an engraving bit is the need to switch tools to cut out the outline.

Is yours a stock spindle? What diameter bit are you using, hanselcj?

Good results anyway.

RobCee, I've got a source for that stuff in acrylic, trade only though. I'll send you a PM later.

Actually, having gone to look, they no longer have it on their website! Shame.
I'll ask around though. It's the type of thing locksmiths with shops have for their engraver machines.

I am using a DW660 spindle. I started off with that because I figured spending a little bit extra on a good spindle would save me heart ache.

All the coasters are 4" in diameter and most were cut with the 1/8" bit I got from inventables. The ones with text and smaller detail were done with either a 3/32" or 1/16" 3 flute straight bit I got from drillman1 on ebay. He calles them 0 Helix bits.

Ikea (at least in the States) is an easy resource for cheap HDPE.

http://www.ikea.com/us/en/catalog/products/90202268/

13.5 x 9.5 x .25 inches (but about 2.5 of the 13.5 is used up because of the handle.)

This might work well for coasters, but isn't the two-tone that Inventables offers.

Ok, the stuff is called "Traffolyte".

No idea about the supplier, someone pointed me to this site when I asked about it.

Yeah, I seem to remember Traffolyte from back in the day when I was involved in designing motor control centre enclosures. They used to use a pantograph to engrave labels in black/white/black Traffolyte (or maybe it was white/black/white). It was a pretty sturdy sort of plastic, but seemed to engrave nicely.
I will look around for some next week.

After seeing someone on reddit making star wars coasters out of acrylic with a laser cutter I had a thought... I CAN DO THAT! It started small with a friend and few coworkers, but after word got out they took off. Now lots of friends and coworkers are getting their school, favorite car manufacturer, or video game put on a snazzy coaster for them.

HDPE is a pretty nice material to work with. I found the following settings worked best with a straight fluted bit. Upcut bits make a huge mess of things.

Time to buy more HPDE. There are a bunch more Dr Who and UCF Pegasuses for me to make.

That's pretty damned cool. I'll be adding that to my todo list once I get her all tuned up. And, I guess it's not a huge surprise given the forum we're in but I was amused seeing the colleges: MIT, GT, USF, AU. I get the impression y'all aren't a bunch of history majors. Love it.

Not quite, I am lucky enough to work with a wide range of disciplines from what feels like every engineering school in the south east. Plus a few of dem northern folks.

Nice material. I hope inventables starts an EU store
