They get warm just sitting there not moving at all.

Steppers do get hot and will get warm when sitting as they are holding position. I think the Geckos will reduce current when sitting idle so that they dont get too hot but a stepper will handle heat that you wont LOL
 Just need to check you have the correct current limiting resistor on your geckos.

This is a new controller I purchased, I just got tired of all the trouble I was having with the other controller.  I installed this tonight ran a program no problem so I hope I am out of the woods now.  This g540 is all new and new motors well they need to be broken in I suppose. 

I am still playing with the motor tuning not sure where I should be on that one.  I am trying to find that place where things are running smooth without all the jerking and squealing.  I am close now but still working on that one.

Just make sure you have the correct value resistor fitted and your motors will be fine :)

another thing I noticed tonight, with the old controller and the drives on I could turn the screw by hand, you won't tun this one.  Now way you will move that it's really locked.

Aren't the resistors in the controller?  This is a turn key controller complete with motors.  I am not sure where to look for that.

The current set resistors should be soldered to the DB9 that plugs into the drive.  They are not internal as Gecko has no idea what motors you will use.  You can remove the hood on the power cables and see if it's in there.
