Well I feel kinda dumb right now. Turns out the 4 wires I have supplying power to the ramps aren't the most stable....which is why the first time I tried the test code, nothing happened and I measured nothing coming from the motor pins. Furthermore the rumbling is a result of me messing with the wiring. Whereas all the diagrams online have a nema17 motor with the wires from the coil going in ordeby ThePinkCow - RAMPS Electronics
Oh okay interesting, thank you for correcting me. So I gave it a break and when I came back, there were two red led's blinking on the ramps board. It seems that this is part of the test code? LED_PIN? When I plug in the motor it rumbles! As in the shaft isnt spinning but looking at the code, it seems like that what's supposed to happen! Going to try and upload something to get it to spin now,by ThePinkCow - RAMPS Electronics
just tried uploading the ramps test code, motor still doesn't move but there does seem to be more resistance in the motor now. However, as opposed to before, now I'm not reading any voltage from the motor pins (1A, 1B, 2A, 2B ). Also I thought the enable pin was only for enabling/disabling some kind of output on the driver and not necessary for simply getting the motor to move? As per this docuby ThePinkCow - RAMPS Electronics
Doesn't buzz or anything, I did get some buzzing when I had the driver hooked up directly to an arduino uno, without the ramps, so I'm hopeful that its not the motors?by ThePinkCow - RAMPS Electronics
Hi everyone, A while back I bought a folgertech prusa i3 kit and put it all together but it didnt work. In an attempt to figure out why my motors were not moving at all, I've put together the ramps and arduino boards with a single a4988 driver. The motor is wired according to this tutorial. There is a power supply connected to the ramps board at 12V and 1.5 A. I've set the potentiometer on the dby ThePinkCow - RAMPS Electronics
