I just switched to a ShopBot Desktop and I'm trying to figure out the correct setup for a production run I'm working on and I wanted to tap the forum for it's knowledge.

The product I'm making can be seen here: magnetcomic.com

Here are the details:
-using ShopBot Desktop w/spindle
-wood: walnut
-each board is 10.5" x 4.25" (0.25" thick)
-I cut three 3" x 3.5" pockets on each board
-pockets are 0.09" deep
-using a 1/4" three flute downcut bit (I also have two flute bits)

What would my IPM / IPS be?

What should I set the spindle RPM to?

What should my stepover rate be?

Anything other settings I should be tweaking?


Thanks.
