I can't find much about the 990H, apparently Rutex is not selling those anymore and there is no documentation on their website. I hope you have all the docs and software to setup your system. > I did a new configuration with Stepconf, will that really work with servo's? > It says in the documentation that it should handle any step/dir config but I > only see stepper motor settings and not really something that is servo > related. Correct, that is the beauty of these system. It almost suggest you don't need to know about servo controllers and PID parameter settings. And that is true - for your EMC config. From the CNC controller software you only need to know about feed rates, and stepper timing - but you will need to program the PID parameters in the servo controller if that is not done by the machine provider. Please note that these type of servo drivers use mostly microcontrollers to convert the stepper signals. They may/will have special requirements on step timing and the moment when you change the direction signal. Do read the manual of the 990H very thoroughly and check your stepper settings.
