Hi, I have a strange problem and i know the G203V is no fault in it  ... My G203V are connected to my DIY BOB and these working very well on my CNC converted Radial Drill Machine...The problem is that, when my computer is off and i power the G203V, the motor holds with very less torque.. a little push of finger and the motor loose steps,.. remember that when the computer is in OFF condition and BOB is getting +5V from the supply. When i ON the computer the motors set very tight and i can not rotate the motor shaft with hand, even with the plier... This is good news... So the problem is now: I have installed an independent rotary indexer controller to my Rotary indexer. This rotary controller is a DIY and a great solution by the STEVE at http://www.cnczone.com/forums/open_s...e_indexer.html ... This indeser controller generates STEP and DIR signal to stepper motor and shows the results on LCD display... It is PIC based controller... Now, when the whole unit is powered up, the Motor gets step and direction signal and rotate but with very less torque..can be easily stopped with hand.... Whats wrong here?... the Stepper Motor is 4Amp and 650 Oz-in bipolar connected to G203V... The Power resistor i installed at G203V is 62K for this 4amp motor... The problem is that on my CNC Mill this behaviour is only when my computer is in OFF condition..The workaround is to ON the computer and you can't rotate the motor even with the plier.. if the computer is OFF then motor has holding torque but very less and can be rotated with little force.. The same happen to my indexer?..How can i solve this problem? STEP and DIRECTION and GND from the controller enters into STEP, DIR and COMMON of Gecko drive... Thanks

| Hi James, You are right if i just power-up the motor without attaching the step/direction lines from step/pulse generator card. The motor should Hold, but as you do not provide the step pulses the motor will unable to rotate. My problem is solved for The Independent rotary indexer. The G203V is working fine for me. Regards
