I can't run a test because believe it or not I only have one small CNC running and it's hard to get to the motors on this one.

I can do later in the week but it is interesting to actually check just what power is pulled on a stepper system.

Geckodrive state that 2/3 of the maximum amperage of the motors is required so if you have a 6 amp motor they recommend 4 amps of power.
i know at one stage when we were doing the prototype X3 kits we worked out that we needed 4 x 2.5 amp = 10 amp divided by 2/3 so we arrived at a 7 amp power supply.

Once built running all 4 axis absolutely flat out drew just under 5 amps ???

So someone do me a favour and stick a test meter in circuit with one of the motor leads, most of the cheap multimeters will handle 10 amp, and tell us what the driver is set to and what it pulls on a rapid move and a low speed cutting move.
