Jim, That is exactly what I am doing. There is no PID, axis.2.motor-pos-cmd is connected directly to axis.2.motor-pos-fb, as follows:
net Zpos-cmd axis.2.motor-pos-cmd => axis.2.motor-pos-fb Regards, Eric another thought. can you take out the pid loop completely? that way the pwmgen just gets the Zpos-cmd and thats the end of it, no following to worry about. or do i need to do a bit more reading? It just hit me how that would work, Z doesnt have to be constantly moving, it's more like moving a sliding pot up or down setting the power. ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
