This is a matched three-axis electronics bundle for small CNC routers and 3D printers: three NEMA 17 steppers rated at 62 oz-in, three microstepping drivers, a 24V 8.3A power supply and one interface board. The drivers run 2.5A at 8.2-45V with 1-1/32 microstepping, so the kit covers motor, drive and power in one package instead of sourcing each part separately. The main decision is the interface board: a parallel board for Mach3, Mach4 or LinuxCNC on a 32-bit PC with a parallel port, or a USB board tied to Mach3 only. It suits builders of small hobby machines who want a known-working set of matched parts and accept modest torque and a software-dependent setup.

This is a 3 axis electronics system for smaller CNC machines and 3D printers. It includes three NEMA 17 stepping motors rated at 62 oz-in, along with drivers, a power supply and an interface board.
The interface board is either parallel or USB. The parallel board works with Mach3, Mach4 or Linux-CNC. It needs a parallel port and a parallel cable on a PC running a 32-bit OS. The Mach3 USB board works with Mach3 only and connects through a standard USB port.
