Hello, I use MACH3 as software and the CSMIO/IP-A from CS. Lab as a controller for my water jet cutting system. I had the problem that the x-axis vibrated when driving (the x-axis is about 3.5m long and the y-axis is about 1.7m). After playing with the controller settings for a long time and without success, I decided to use the "Auto-Tuning". As a proportional gain K_p i get a value of 125000 for the x-axis and a value of 9500 for the y-axis! How are these values ​​scaled, does anyone have any idea? The difference seems a bit too big to me, although it works (vibration is gone)!??
