Al,

Why not just order some fuses from Geckodrive? The fuses inside the G203v are extremely fast acting. Most regular fuses will not blow fast enough to protect the internal Gecko G203v fuse.

Renraku,

I'm sorry. I may have confused you.

It not necessary to change that resistor right now. 47k will let the motor pull about 3.5A. 62k will let the motor pull about 4A. During the...

The jumper on JP1 (directly below the PMDX label) is set correctly for the G203v stepper drivers. (The jumper bridges Gnd and the center pin.)

The Star wiring is correct. You have one wire going...

Renraku,

Start simple. Connect only one G203v. Connect only one motor. Configure Mach 3 as that the one motor is connected to the X-axis. Experiment until you understand how to drive that one...

You have correctly matched the motor's wires to the proper terminals on the G203v.

Because you have wired the motors half-coil (instead of bipolar parallel), you should use a lower value resistor....

Bart,

Figure 4 on page 9 shows that the step/direction signals are deactivated whenever the E-Stop switch is opened.

Figure 5 on page 12 shows that the signals going to J8 are also deactivated...

Dirk, I think the problem is the relatively high step/direction signal current requirements for the G201 and G202 stepper drivers. Those two stepper drivers require a minimum of 15mA to drive the...
