Demo configuration please? > So, lincurve is perfect for making your PID gains vary with spindle > speed. That is an interesting idea Andy, but with 3 uptodate LCNC installs here that DO include the docs, I find it puzzling that there is not now, an installed man page for lincurve on either of these 3 machines. I'd swear on a good sized stack of bibles it was there last fall when I configured that. This is the current 2.5.3 build, updated in the last 24 hours. So obviously, the doc build is still kaput.
