General Mach Discussion / Re: motor tuning

Chad is right... Others settings will not help you.
It really is down to your own machines loads/friction etc, your drives, whether you are microstepping or not, and the voltage applied to your drives.
I would not have the two motors linked as you suggest, it may even make matters worse. Mach can slave axis's as yo may already know. I assume you are planning on using two drives also for that axis?
It also helps with steppers to drive the machine 1:1. I'm still amazed how many people assume they will get more torque by using reduction. This can be self defeating as the motors torque drops off rapidly with speed.
You jus got to try it out. What drives are you using?
