General Mach Discussion / Re: motors stalling

I love you man. what did it for me was what you said about the motors having one coil energized. I went back to the test program, the one that showed the same voltage on all four terminals and the shaft of the motor could be turned by hand. In the mach 3 program you can't turn it by hand, meaning voltage was applied to one coil and thats why the terminals were showing different voltages.  It all makes since now. Then I simply changed the steps/unit to a lower number and the motors spin just fine. The other day I don't think I was hitting the save axis settings, I was just clicking the "ok" button, That why it wasn't working when  hood posted that suggestion.

Thanks to everyone but I'm sure I'll be back with another stupid question.

I tried setting the step pulse and dir pulse to 5 and the same thing happened, the motor still locked up after 1/4 a rotation.  If I change the jog rate to 15% the motors run fine but the volt meter readings are still weird and the the motors still get hot when there not doing anything.

Thanks for trying chip.

Changing the step/unit, acceleration, or velocity doesn't do anything.  well to help anyways.  I also wanted to add that when the power supply is on and the motors are in standby, the resistors and motors get super hot. I think it has to do with the motor terminals not reading the same amount of voltage.  I could really use some help.

I need some help.  when I jog my motors they spin once, stall, and make a nasty noise.  They seem to work just fine with the stepperworld test program, VBStepDirXP. When I hook up my multimeter two of the terminals of the motor read .4 volts and the other two read 3 volts. Whats going on?
