As I said before, your spindle and tool choice will be the limiting factor in how fast you can cut. 100ipm is actually very slow. You're current machine should be capable of 3 times that, if the spindle is up to it.

Ok this is what I'm talking about !!! Great Feedback!!!!!See I've already built one machine which runs with a Gecko g540 and CNC ROUTER PARTS 380oz/in steppers and belt reduction units. It's 4x4, but just need a bigger machine now, and I really like what PMDX has done with their components so they integrate with Gecko drivers perfectly. Also the "fanless" idea with the big heatsink is also good idea. IF............. I use what I had stated in the beginning, is this a good setup? Other than the power supply being on the big side. And which one should I use? Will this let me cut birch plywood at say 100IPM in one pass using a PC 7518 router? The hardwood flooring that I've been doing is mainly alot of inlays no deeper than 3/8. But when I cut the whole design out I would like to cut it in one pass if possible. Thanks for the valuable info guy's.

Thanks ger21 the machine I have use's a Porter Cable 690 . It will not cut 3/4 birch ply in one pass at 60 ipm. It's just not strong enough. The new machine will use a Porter Cable 7518 3hp.I only use Onsrud bits 1/4, 1/2. Thanks
Does the spindle stall?
A 690 should be able to cut over 100ipm easily. Is this baltic birch plywood, or regular plywood? What specific bit's are you using?
At 60ipm, a 690 spinning at 27,000 rpm would dull the bits very quickly from excessive heat. Changing tool type can make a big difference. You can also try making 3 passes at 300-400ipm, which would still be faster than 1 pass at 60ipm.

Kinda ,yes it just slows down as if the feed rate is too fast. The bit is a Onsrud 60-005HH - Spiral Chipbreaker, Helix High, Solid Carbide, 3 Cutting Edges. I've replaced the bearings twice in 3yrs. But I do cut alot of 3/4 standard birch plywood. And just in the past yr have been cutting floor inlays.
