I NeeD HeLp PLease AM882 a good choise

[JAZZCNC]

Hello Juan and welcome.

First the Am882 drives are excellent drives and easy to setup. Most people having troubles has been because of user error and nothing to do with drives being complicated or faulty. In there basic setup they work just like any other drive with simple Dip switches for selecting appropriate motor settings and Micro stepping. Where they shine above other is the fact you can fine tune them to match and get the best performance from your system if needed or desired by using the tuning software.

BUT.!! . . I think your making a mistake often made by going for Big Nema 34 motors.? Bigger is often not better in CNC and it's important you match motors to machine. . . . . So what machine are you building or converting.?

Problem with Nema 34 motors is they need high voltage to get best performance and your proposed largest 60V supply will be far to small and really the AM882 drives Max 80V would be the lowest you'd want to run at and really I'd recommend getting high powered drives like these 2M2280N Digital microstepping driver to get the best from those motors.

Unless your building very large heavy router or converting a large milling machine you probably won't want those motors.?
Give more information on what your planning and we can help guide you to what will work best. Give details like linear rail type and drive system IE Ballscrews or Rack & pinion etc.
