Arduino and Ramps are perfectly capeable, so telling him to get a "decent board" is really just a very misguided sentiment. I have 2 psc 32bit controllers incoming, but Ramps is a very capeable solution, especially considering the Price.Quote

I hate to be blunt - but isn't it time to consider buying a decent board? Something in 32-bit, made & supplied by a reputable company?
RAMPS/Arduino can be OK (one of my printers still uses it) but many of the Chinese-made boards are of barely-adequate quality and fail with monotonous regularity. I have a RAMPS shield somewhere that has never worked, even after I'd cleaned all of the minute solder splashes off its back. There have been so many other instances of problems such as this.
Just think about how much all of those cheap boards have cost you, when you add them all together.

Totally agree with thatQuote

I have a Ordbot Hardon with a Mega Ramps controller.
Perhaps to start over
Find a known good Arduino Mega (test it with example sketches)
Mount your best RAMPS on it with good stepper drivers, jumpers in the right place
Test your power supply measure under a load.
Check all connectors and connections, anything suspect measure for continuity
may be a good time for all cables to be 4 pair shielded cables even end stops
With all that
Load RAMPS test code
[reprap.org]
It switches on and off all the MOSFET outputs (this will make the leds blink) just be careful not to have the heated bed and extruder heater connected unless you want to heat them. Plus it will move back and forth all the stepper motors connected.
If that works OK
Configure and load repetier firmware
Print away be happy

Most problems really stems from bad user-wiring and the occoasional bad driver. 1 driver can sabotage everything.
Calling all Chinese products for bad is really just an uninformed statement. Most of these consumer Electronics come from China, and yes, some are bad, but most are very good. Only BAD ramps/arduino I ever got was manufactured in the UK.
I have bought from several Places in the EU and from China.. guess where it was all made? That's right, in China. Except the faulty piece from the UK.
I'd sit Down and test everything... starting by finding a working arduino and then go through the ramps boards one at a time. Then test the arduino's using the working Ramps, if you have no other way to do it.
