Steppersonline DM860t ?


I am trying to get Some DM86OT Digital Step Drivers to work with the Masso.

I am using Some Longs Motors 34hs2840 Motors,with 48 volt power supply.

I have the Dir+ and Dir- wired to the Dir terminals

And the S+ and S- wired to the Pu terminals on the driver

have a 2k Resitsor in lin elike it shows on the diagram

have the Amps set correct

But can not get the motors to turn at all

Anybody have any Ideas?
