Thanks for checking, Sam, and good to know. I'll try sim on my version but I doubt it will be different to my "real world" version. I use the same low-passed spindle encoder velocity on spindle-speed-in. I'll try to find the difference between the 2.7 and 2.8 code then (or the difference to the machinekit branch). Karl
