My Gueko 212 Driver doesn't work in Full/half step

[Chivo]

I have a problem with my step motor, It doesn't work in full/half step mode.
It only works in 5u ,10u microsteps. But It loses steps when I change directions very fast (jostik).
But I want more torque, and microsteps doesn't give you that.


The default jumper settings on the G212 are:
1) Auto-standby current enabled (2,6 jumpered)
2) Normal current range enabled (1,5 not jumpered)
3) Anti-resonance enabled (3,7 not jumpered)
4) NEMA-42 disabled (4,8 not jumpered)

5) Input option header set to 'common ground' (1,2 3,4 5,6 7,8 jumpered)
6) Resolution set to 'full-step' (1,2 jumpered)

What do I have:
*Mach3 and Mach2, loaded in a PC AMD 1.9 GHZ with WIN XP Pro.
*Breakout Board form PcMinMo. I'm not using the pin 1, only Pin 2,3,GND
for X Axis. (I built it)
*Step Motor Driver from Gueko (G212)
*Power supply:1.1 Amp / 68Volts DC after rectification(10 Amp) and
Capacitor of 1000uF. (I built it)
*Step Motor: 7.4V - 1.3A - 180 steps/r - 6 wires
* 7) terminals 11 and 12 with a 10 k 1/4 watt resistor.
