Stepper motor controller question

[Silvia]

Have a nice day!
I bought 3 Nema 23 Stepper Motor Bipolar, rated at 4.2A, 3.78V, and I have a problem, I would like to know which motor driver, 3 axis controller and power supply is best for a homemade router, or any driver will do
Thanks in advance

With stepper motors you need a decent supply, plenty in reserve will not go astray.
Some of the 3/4 axis controllers they recommend are a bit out-moded these days.(TB6560)
I think there are much better units now.
Voltage probably upwards of 20v and current (with 3 motors) probably around the 20-30A as well.
Driver takes care of motor current once programmed (set).

Definitely needed to upgrade.
