Hobby Pro Driver power save function

[normunds_a]

I have notice that steppers are turn off any way. There is no matter if the jumper in on or off.

I use Mach 3 software and when I start moving after they are turn off then strange noise is coming from steppers in firs moving seconds, but when the steppers is moved and the power save is not turned on sound is ok. The feed rate and others setings not inflace it. Have eanybody have the same problem?
I use:
1. 24 V power supply 3A
2. replace resitance to drop down 30% energy not 50% as default
3. steppers 305 oz
