[sjotime!]

chmillman,

First, thank you! Appreciate you taking the time.

Second, regardless of what I enter for feeds and speeds in the interface you reference, my G code has F20.

Any other thoughts?

My cutter manufacturer is a friend who built this machine then didn't have time to use it. 5' x 10' (1.75 x 3.3+-m) cutting area with a 2 HP router (12000-30000 rpm). This is a CNC router, not mill. I don't have any idea what appropriate feeds and speeds are for MDF and birch ply, the two materials I will probably cut the most, but I haven't searched for them either. I will track that down and put it in the FS file you mention. If you know appropriate f and s I would be grateful for the info.

Thanks again!

Dan
