If it comes with everything in the picture, including the shop, I'll take one.

Decent price on that first one but only 250 ipm? That's really slow on a big machine like that. The second one says max speed is 800 ipm - much better.

They look like beast of machines. I'll stay with my cncrp pro4824 with the NEMA 34 electronics.
Question: How fast do people push their tools. I know materials/spindle are probably the main factors, but I've only gone 100ipm. I think my gantry would handle most any speed without flex before the tool snaps. Well unless I'm using a 1/2 endmill or something really ridged.
I'm really not sure what mine is capable of. I'm using a 3hp router too.
Maybe a better question is what is the fastest you have run your machine and what material was in on. Router or spindle.

Don't forget to figure in the price of removing the roof and the crane rental to lift into unroofed shop. Those things are beasts. My wife thinks it's a shame I don't have room......oh well.

My machine only has Nema23 steppers, and I usually cut between 200-250 ipm. I've got a new ballscrew coming for my Z-axis (1610 replacing a 1605) and I hope to be able to up that (my Z-axis can only do about 250).

I would expect your machine could handle 350-400ipm relatively easily.

That's scary. I'll bump mine up to around 220 sometimes if the cut is going good, and that makes me nervous watching it knowing it'll do better than twice that.

The fastest I have cut is 400 ipm with a 1.5" flat bottom cutting to surface the MDF spoilboard. I was only taking about 0.010" to clean the surface but it was flying!! :grin:
