Help with controller wiring - Gecko 202's
I wired up my router this week and was hoping to spin the motors this weekend for the first time, but can't get it working.
I am using a 24V 25 A power supply, 3 gecko 202's, CNC4PC breakout board and an external 5V power supply from CNC4PC as well.
When I turn the controller on, I get 24 v to the gecko's, 5 V to the breakout board. The red LED light is on on the Gecko's and BOB.
Problem is that the motors wont lock up.
I have the +5v from the CNC4PC power supply going to the geckos as required, but where do I hook up the ground side of this to? Could the fact that this is not hooked up yet be the cause of the motors not locking up?
If not, what else should I check for?
Thanks

Got it working ------Somewhat
Well I got it working. Somewhat. I got all 3 axis to move by removing the current set resistors. Must have them figured wrong, but I figured that problem out at least. I will have to get some new resistors. All 3 motors lock up very strongly.
Now a new problem. Only the Y axis runs properly. I have had it running over 300 IPM today with no problems. :banana: Stopped there but could have run it faster. I not to sure I will ever top it out at least until I get some limit switches installed.
The X and Z axis work very ragged. Very choppy and the Z axis wont hadly even move. I disconnected everything on the Z axis. The motor is only turning the screw at this point and is unable to do so. I don't have the slides hooked up or a router of any kind to weight it down, yet it will still not turn properly. I feel as though I have eliminated any alignment issues by doing this as well. I am able to turn the screw freely when the steppers are not powered. :confused:
I suspect the x axis is the same as it behaves similarly. Can anyone suggest any solution to this problem? How can I test to see if the motors are receiving current as needed. Which wires would I check?
I have read about trim post adjustments, to adjust the midband compensation circuit. Not sure what this is, but could it be affecting 2 of the 3 motors?
Thanks all.
