Keling KL 5056 not working

[SwampDonkey]

Well, I have a frustrating mystery on my hands. I have a 3 axis machine using 2 DQ542MA drivers (Chinese from Ebay) and one KL5056 driver from Automation Technologies here in the US. I bought the first KL5056 and couldnt get it to work, contacted AT, sent it back, got another one and now THAT one doesnt work.
This is weird because ive heard that these drivers are very reliable. Im thinking Im doing something wrong but cant figure it out. The other two cheap chinese drivers are working fine.

Any suggestions?

Double check your DIP switch settings. Can barely tell from your photos but I think the Keling driver has a legend silkscreened on it that describes the state of "off" and "on" for the switches. I was previously thrown off by a Keling driver because off=1 and on=0 when decoding the tables.

As far as I can tell I have it set for 10 microsteps and half-current at idle. Also set at 5.6 A. Ive tried several combinations.

Shouldn't it move somewhat despite dip-switch settings?

What does the silkscreen say is the state of the dip switches for a "0" or "1" state? Try showing a focused picture of the writings on the front of the driver and also of your dip switch settings.

The motor may not appear to turn if the dip switches are opposite of what they need to be set to. Your max current would actually be min current and your microsteps would also be off. This was my experience.

Try disconnecting the 5v enable wire on the driver. I found today the my KL-5056 drivers disable with 5v at the enable connection. Seems opposite to what I'd expect but I didn't get any motion from my drivers until I did this.
