Hi, just wanted to ask if you found an answer to your question. I have a ramps board and want to control a similar pump for a pick and place machine.by bt_Tama - RAMPS Electronics
So I think I found the error. I did not adjust the potentiometer on my drivers. The ref voltage was set to 1.6V. After setting it to 0.45V, everything is working.by bt_Tama - RAMPS Electronics
Oh, you're right. This proofs that you'll learn something new even after a failure. The question still remains. What did I do wrong? Maybe the orientation of the driver was wrong, as you already said. Or maybe my PSU connection was switched. I'm pretty sure that I did everything exactly as I recreated in the pictures above, though. And as far as I can tell, everything is connected the right wayby bt_Tama - RAMPS Electronics
So what I found while checking for shorts is that in continuity mode when putting one probe to the plus and the other probe to the minus connector of the 5A channel, I do get a very short beep from my multimeter (just a fraction of a second). Maybe the D2 diode is shorted? But then my question is: Why isn't it beeping continuously?by bt_Tama - RAMPS Electronics
Hey Viktor, thanks for helping. I'm pretty sure that the driver is oriented the right way, at least according to the pin description next to each pin (maybe it wasn't at the time it happened, though...?). I also checked this page here. Well, I connected a 12V 5A PSU to the 5A pins on the board (didn't connect anything to the 11A pins). I thought that the board will only draw as much current asby bt_Tama - RAMPS Electronics
Hello everyone, So I’m new to this, and I’ve recently bought some stuff for a private pick and place machine. In order to learn, I first wanted to try and control a single stepper motor and obviously did something wrong because when loading my script I first heard some kind of “click” and the driver started to smoke. I immediately unplugged the power supply and USB A cable. But first, here is aby bt_Tama - RAMPS Electronics
