I don't have 2.7 here.. But in 2.8(master) lathe sim works as expected. This short program
G95 s100m3 g1z4f.001 g0z0 m30 Z moves to 4" at .1ipm (which seems right 100*.001=.1) Changing the spindle speed changes the feed. Looking at hal in the lathe sim - the motion.spindle-speed-in is hooked to a low-passed spindle encoder velocity. sam On 12/9/2014 6:38 AM, Karl Jacobs wrote: > Thanks for the info.
