Hi,
new to this list with a question about G95 (units per revolution) for 
lathe operation in machinekit/emc/linuxcnc 2.7.0~pre0, running on a 
BeagleBone Black. G76 (threading) and G33 (synchronized motion) works 
nicely and the feed speed in Z reacts to the motion.spindle-speed-in hal 
signal as expected. But G95 gives me feed speeds independent of 
spindle-speed-in, corresponding to a constant one revolution per second 
of the spindle/encoder speed. I see motion.spindle-speed-in changing 
when I command it to change, but no change in Z motion speed (well below 
the speed limits).
I can rule out hardware problems of an encoder by using a hal siggen 
component to drive the hal encoder inputs (Phase A and Z, counter mode) 
to simulate the spindle speed signal. That must be working correctly 
because G76 and G33 both give the right result (my X and Z axis 
components drive a real lathe so I can watch and check the motions). 
What am I doing wrong or not understanding?
Karl
