Hello everyone,
So I'm almost finished with my first reprap build. I have the sanguinololu soldered and sprinter uploaded with all the steppers and endstops in place. I was just about to start my first test run when I tried to connect one of the steppers to see if it would work... and it didn't, nothing happens. I thought that it might be the power supply so i bought a new one and it still wont work. I'm using the 4 pin 12 volt connector, but when i put a multimeter across the +12 and ground pins, it only shows about 2.25v. do i need to add a load to other pins on the power supply to get it to work? could it have something to do with me using the A4988 drivers with sanguino 1.3a since i now have 2 100k pullup resistors? I didn't think that would make much of a difference. Any help would be appreciated.
Thanks!
