My electronics setup:
I was up to set the drivers potentiometers, but I’m getting 0.00 values.
X, Y and Z at LCD show zero/question mark alternating.
Can’t move any motor through LCD or Repetier-Host
Can anyone point some direction?
Unplug the usb, does it still work at all?
Thank for you quick reply, Ryan!
The LCD turns off when I unplug the USB… I guess everything goes off!
So either your power supply is dead or your board is.
My power supply shows 12.20 volts, and Ramps reset button resets everything when I click it.
Are there some tests that I can do in order to discover what is wrong or dead?
Then your 5V regulator is dead, same reason I stopped carrying import ramps. If you can solder I have regs in the shop but it might be cheaper just to buy a new ramps.
Cloud be the drivers perhaps?
Take them off and try one at a time but if the screen is not on your 5V is gone.
I’ve got Arduino Mega, LCD, Ramps and the Driver from about 2 years ago… I’ve just started to build MPCNC December last. But I remember that screen never worked if Arduino isn’t plugged by USB. I think Ramps already came fried, because three mosfets looks intact and not even smells burned.
I’ve looked the Ultimachine’s boards you are using now. We don’t need to care about Arduino and driver, its “all in one board”. Its amazing! Unfortunately it is very expensive converting to my country’s currency and import taxes. By now I’ll take another Ramps, that costs less than 10 dollars here and I’ll find another way to contribute with your project.
Thanks Ryan!
The ramps board is pretty hard to kill. The regulator is on the Arduino board.
I got a new Ramps, and now its working!
With the Ramps boards, it is typically the Mega that fails. The Ramps hat part (the part that carries the drivers and plugs) may still be good. Test the old one with a new Mega. You may find it still works.
