Hello Jonathan, is there any power supply do you recommended? Jazz told me to buy this [URL="http://www.zappautomation.co.uk/en/digital-stepper-drivers/318-2m2280n.html"] but I have the same problem( I can only buy on aliexpress and ebay) maybe you can recommend another power supply so I can find it, I dont now if I need one or more than one. Thanks,you have been of great help.
One of the problems with most Off the shelf PSU's is they all seem to fall short of the ideal requirements either on Volts or Amps so you end up buying 2 which makes it expensive and more room required in control box. So given your location then I would think it would be easier for you to locally source the parts to build one than trying to source ready built PSU to suit your needs.

Thanks Jazz, I'll wait until buying the nema and drivers, and if you help me I think I can make the power supply. I have the tools, digital tester and welder to be able to do it. IŽll keep you posted. Thanks for everything!
Hello guys I recieved all the goods from china for the cnc
2pcs RM1610-1500mm Full length 10 pitch
2pcs HGR15 -L1500mm
1pcs RM1610-1200mm Full length 10 pitch
2pcs HGR15 L1200mm
1pcs RM1605-350mm Full length 5 pitch
2pcs HGR15 L=350mm
5PCS Nema 23 stepper motor 425oz-in,3A,2ph,1.8°
1pcs 6 axis cnc DB25/ interface board adapter milling engrave c10
I want to thank you for your help, thanks to you I could select the components. I would like to know if you could give me some advice regarding the spindle selleccion. I have a 2050W router and do not know if I should use this or if it is better to buy a water cooled spindle or any other,since I donŽt know if the power that I need 2.2 kw or 3 kw is suitable for milling materials I will use.
On the other hand, I want to ask JazzCNC for help to build the power supply appropriate for this equipment,and to help me decide on the components I should buy to make it. And finally I would like to know what I have to do with the components, what procedures I need to follow.
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!
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.!
