Problem- GECKO W/202 AND PMDX 131

[glengen3]

I HAVE BRIDGEPORT BOSS CNC WITH TWO SIGMA STYLE AND ONE SUPERIOR STYLE STEPPERS. ITS POWERED BY 2 22OV/ 48V 1OOO WATT STEP DOWN TRANSFORMER. BOTH PRIMARIES AND SECONDARIES OF THE 2 TRANSFORMERS ARE WIRED PARALLEL AND IN PHASE WITH EACH OTHER. THEY FEED THE POWER TO A PMDX 135 FULL WAVE BRIDGE RECTIFIER THAT PUTS OUT 70VDC, TO POWER 3 7AMP PER PHASE GECKO 202'S. 118VAC POWER IS DRAWN OFF THE CENTER TAP OF BOTH PRIMARIES AND IS USED TO POWER A PMDX 131 BREAKOUT BOARD. THE PROBLEM IS THAT THE STEPPERS ONLY PULLING ABOUT 1.9 AMPS WHEN STEPPING. THEY HAVE VERY LITTLE HOLDING POWER , AND ALMOST NO TOUQUE WHEN STEPPING.
ALL VOLTAGES HAVE BEEN CHECKED AND APPEAR TO BE CORRECT.

THEY ARE WIRED AS FOLLOWED:

SIGMA

3 TO PHASE A+
1 TO PHASE A-
4 TO PHASE B+
2 TO PHASE B-
7 JUMPERED TO 8
5 JUMPERED TO 6

SUPERIOR

A+ TO 7 AND 4
A- TO 5 AND 8
B+ TO 1 AND 2
B- TO 6 AND 3

WHY DON'T HE STEPPERS HAVE ANY POWER?
ARE THE TRANSFORMERS WIRED INCORRECTLY?
HOW SHOULD I CONFIGURE THE PIN AND MOTOR TUNING SETTINGS ON MACH 3.

THE GECKOS HAVE NO CURRENT LIMITING RESISTORS.
