This isn't a showstopper, just an annoying thing that I've been trying to resolve.
I have an older Isel 3-axis router. It's not fancy. It drives a PC router for the spindle, and I leave it set typically at 10k rpm. My machine wants to cut at 140ipm or less.
Now the question is, where/how can I set that up in my config file, so that the system feeds and speeds uses the 10k rpm and the .008 feed per tooth that I usually use to calculate feed speed. Every operation I program, the system feeds wants to run @ 2505.7 rpm.
Is there a trick to using SFM that I should just accept? If I run 500SFM, and a tooth feed of .007", than the system feeds wants to run at 2505 rpm, and 106 in/min, which is fine, but it's not right.
Any insight / education appreciated.
Thanks in advance.
