Hi! I need to ask, because I fried 3 drivers, and I have to be very carefull with the others 3 I have (lucky of me xD). So:
-I flashed marlin without ramps conected to arduino. Then plugged ramps, drivers and lcd. Conected the power supply and nothing happened (I cheked that it was at 12V)
-Then i realized that I needed to flash marlin with ramps connected, so unplugged everything except ramps, and reflashed. Ok till here.
-When I connected with USB (only) computer recognized it, but when I started to add the drivers(disconecting the USB between each one), a “desconnected sound loop” started on the computer. After researching, I found that maybe the drivers where fried. So I tried again with the new ones, and thats it, now I can connect arduino with ramps and the 3 drivers all together, and the computer recognizes it (hurray!!)
And now im afraid of repeating the mess. My doubts are:
1-The drivers got fried because of the falsh without ramps? or maybe because I turned on the PSU without the motors connected? (im afraid of turning on the power with the good drivers installed)
2-Also, I want to adjust the voltage of the sttepers for avoiding more injuries before anything, Can I don this with ramps connected to the computer? I think I need to turn the psu on, but there we go to point one 🙁
3-And finaly, Im using Chinese A4988 drivers with Nema 17 motors (2,5A), if im not wrong, the correct Voltage would be 0,5V for each stteper??
Thnaks in advice, electronic part of the build is the hardest for me, and im so close to get it running 🙂
PS:Sorry for my english, i do my best.vicious1KeymasterAugust 18, 2016 at 9:18 amPost count: 2627
We generally use different drivers around here so I can’t help you with the correct voltage.
Make sure they are facing the right way on your board, quick image search will help.
The drivers and ramps do not need to be connected when the firmware is flashed, be they can be.
Make sure your power is only coming into the green plug on the ramps board.
To adjust the driver pots, the ramps has to be powered up, but it does not matter if the usb is connected or not.ramajacParticipantAugust 18, 2016 at 10:33 amPost count: 11
Thanks for the answer, you were right, I was noobing so hard facing the driver to the other side cause I got confused with the assembly instuctions 🙁
I could turn on the power supply without damaging it, and repetier-host also detects the “printer”. But im not able to move the motors from there. As I am using your marlin code, should I change something because my drivers are different from the ones that you use?
As I saw on the ramps wiki, I changed the jumpers, cause Polulu use no/yes/yes for microsteping, but still cant move them.
Is there something I am missing? I am doing this with the power supply and the USB connected. Baudrate set at 250000, like the code.vicious1KeymasterAugust 18, 2016 at 10:38 amPost count: 2627
You need to cut all the steps in half in the firmware and use all three jumpers.ramajacParticipantAugust 18, 2016 at 11:20 amPost count: 11
Infinite thanks for your support, but still the same, nothing moves, even from the LCD controller. Maybe im missing something important and my brain is swamped today.
Tomorrow will be another day, and I will recheck everything again.
Lot of thanks!! You are a genius and a very attentive man!! Tomorrow I will post what i found 🙂

Make sure you have the resistor plugged in.ramajacParticipantAugust 19, 2016 at 10:00 amPost count: 11
Resistor is ok, i corrected the first temperature error that repetier had. This is the response repetier gives to me. I think everything is ok, but maybe im missing something. I tred with 2 different motors and is the same. Also tried on different axis, and nothing again. I also post a picture of my build, but I think that everything is well connected.

Printer stands on idle, after sending movements on the axis. It “makes” the moves, but anything move.
At least today finished assembling my middle parts, and looks pretty rigid and square 😀 Im so close that I can smell the wood cutting 😛

Looks like an opengl error. I think you can turn off opengl in the settings of repetier.ramajacParticipantAugust 31, 2016 at 1:08 amPost count: 11
Finally I solved it. Tried with a different driver, and it was the problem. Chinese drivers can give you a big headache sometimes :S
Wired the motors, finished assembling all the machine, trimed them with enough voltage, and everything seemed to work smoothly, when I made a short circuit on my board with a wire that I was moving above it 🙁 Another arduino and ramps are on the way, and now im printing the case to prevent this from happening again XD
Thank for the help, next problems will come when calibrating the machine 🙂
