I NeeD HeLp PLease AM882 a good choise

Hello guys I recieved all my stuffs from china,I want to build the psu suit for my needs. Can you give me an advice to buid it please.
I have Axis X=2 AM882,Axis Y=1 AM882,Axiz Z=1 DQ860MA,four Axiz=1 DQ860MA,Motors 4PCS Nema 23 stepper motor 425oz-in,3A,2ph,1.8°. Thanks for everything!

Contact me thru PM with your email address and I'll help you with PSU but won't do it over the forum as it can be miss understood by others and potentialy dangerous and damaging if done wrong or misunderstood.! . . . . . . Others may offer over the forum but I'm not prepared to do that.!

Also At the moment looks like you plan to use AM882 for X & Y with DQ860 for Z & A but you have bit of a mixed up setup there mixing digital drives with Analog drives and if Slaving A axis with another(X) to form twin motor axis then you would be much better using same drives on each.! The AM882 would be best for this because they have stall detect and fault signal.

Another thing is the motors.! Which motors are they and do you have a data sheet or model number.? Becasue you quote 425oz rather than Nm I suspect these are the high impedance motors often found cheap on ebay.? If so be aware you will get much lower performance from them for the same amount of Voltage compared to same power motors with lower impedance. This will affect the feeds you'll achieve and lower the amount of torque available higher up the speed curve.!

Yes they are high inductance - the lower phase current (3A) is the giveaway.
