Cwd556. Now what i will say is I did have to change the steps per unit but nothing else was changed. From changing the driver what i did notice was the sound of the z going up and down was considerably louder?
I don't know the DM856 or the Cwd556, but if you are using CSMIO then I think one problem can be the pulsing frequency. If I am not wrong, CSMIO is capable of running much faster than 200kHz and most drivers can only handle maximum 200kHz pulsing. Perhaps that was not an issue with the DM856, but may be an issue with the Cwd556. I know I can run my DQ542MA at 400kHz, even though they are also only for 200kHz, but since I occasionally experienced some issues when I ran them outside the specs, I reduced back to 200kHz and my problems were gone. So, have a look at your pulsing frequency and reduce to 200kHz if set higher. Also check the specs of Cwd556 regarding this, and keep your pulsing at or below that level.
