PoKeys / Re: Z-axis jumping in feed speed (turning)

hello,
I have a quick update. I read a post about electrical noise.
I notices a mini fraction of a second that the rpm was out of control (and the reaction of the machine jumping)
first i upgraded my aluminium sensor wheel with a magnet for a stronger detection signal. (aluminium gives a weaker signal).
The was better but the problem was not completely gone.
I checked my cable of my rpm sensor. i had bound the cable of the sensor to all the other wires of my machine. I isolated it from them: separate routing of the cable and i gave the cable a metal cover (metal speaker cable sleeve) from start tot the pokey board connectors. I also put a thick metal plate between my servodriver and the pokeys57cnc.
After these mods the problem was gone!
I hope it will stay that way.
I tried the same programs and threading, which went ok.
Regards!
