Wiring stepper motor's to Wantai DQ 860ma drivers

I have my motor hooked up to the driver, when I try to jog the motor with the masso jog set on continuous it only turns 1 revolution. I think I need help setting the dip switches

I am using 36volt power supply's. The motors are Nema 34 HST 9085-02B2 8wire motors, 2.0A(U) 1.8 deg/step. The driver are Wantai DQ 860ma.

I have the dip switches set 1 on, 2on, 3off, 4off, 5on,6on,7on 8on. Any help would be appreciated Thanks

How do you have the motors wired, are the coils for the a and b side linked? You only have four outputs for the servo on the driver you have, so the two coils on the A and B side have to be connected.

I think I have the motors wired parallel. I have 8wire motors, I have orange/green B-, white/brown B+, yellow/black A-, red/blue A+. The motor seem to be turning ok.

Which way is best Series or parallel. I am using Long's motors nema 34 HST 9085-O2B2, Wantai Drivers DQ 860ma. How do I know when I have the dip switches set right for my motors. I am using 36V power supplys, suggested by long's motors. The dip switches are now set 1-on, 2-on, 3-off. 4-off, 5-on, 6-on, 7-on, 8-on. I don't have the motors hooked up to anything yet, just trying to get them to work on the bench. So any suggestions would be greatly appreciated. I believe you are in Arizona if so we should be able to communicate other that through this forum. So thanks for replying

There are two different ways to wire either tie the center coils of the A side and B side to make one big coil or hook them up like you did. Either way works parallel gives more torque and series gives more speed. (what I have read on stepper sites)

Hope you get it running OK. I have been having a time getting mine working. I need to upgrade the power supply and stepper drivers as I only have 24v now. losing steps and wont home to the same place twice! I have the PS ordered, hope it cures the problem.

Watched Peter CNCnutz videos and ran his calculator it said I need 52V and 11.5 amps. So I am getting a 48v with 15 amps unregulated toroid PS. I will let you know how it works...

I tried to down load Peter's calculator but could not get it to work. My motors and drivers can take up to 80v, I am currently using 36v . I ordered a 70v from amazon to try it out. With 36V I don't seem to have enough torq. Are you located in the US or else where?
