As I'm getting more familiar with the Vectric software and trying different bits I was trying to find the max ipm these machines can travel. The website specs say 200 ipm and the manual says 315 ipm. I thought only the Elite could do 315 ipm.
After looking at some other cheaper brands it appears they can even go faster than 200 ipm.
What is your guys' experience?

Is there a reason you would ever need to go faster that 200 ipm?? Commercial machines go faster, but not with 1/4" cnc bits. they would just snap off.

Stepper motors lose torque with speed, which is the opposite of what you need for increased IPM. While you may go faster than 200 IPM with no or light load, in general, as you increase IPM you increase the load and probability of missing steps which will result in you cutting a different path than intended. So to err on the cautious side and for smoother results many cut in the 100-150 IPM range most of the time.

I was mainly trying to find out the correct information. I am entering all the machine info into the cnccookbook app so I can more quickly calculate feeds and speeds. I have a lot of different bits, some from Amana, Kyocera (eBay), and Freud CNC that I need help with. So when entering the info I didn't know what the true number was, 200 like the website says or 315 like the manual says. Right now I've only been experimenting with 100ipm with the 1/4" endmill and 75ipm with the 1/8" endmill. Both at 18k RPM cutting through 1/2" plywood. I have some smaller pieces I need to use a 1/16" bit for and needed some direction, so that's why I referred to the Cnccookbook. Still learning.
