Aimee,
For what it is worth, I recently made a set of alphabet blocks with 2 graphic images per block, 2 letters in caps and 2 letters in lower case. I made my own blocks from poplar as tests, then the final from Maple. The Maple cut much better. I only did one set so far. It was a gift for 1 year old niece. I made the blocks first. Then I cut them. Finding a good way to lock them in place on the CNC was difficult and a number of times I had block break loose, which destroyed a number of blocks in the process. I need to be more creative in my work hold techniques if I want to do more of these on the CNC. It was pretty labor intensive, even with the better cutting that Maple gave me. They came out great, but I see that I need fine tune the process a bunch if I wanted to make more of these.
Lasering them once the blocks were cut and sanded would have been a piece of cake. Though I really preferred the look and feel of the CNC cut blocks.
I was not cutting aggressively by any means. I rough cut with an flat bottom 1/8" end mill and then finish cut with a 1/16 tapered ball nose for what that is worth.
