Ill agree with dc42's comments aswell in the most part, but all electronics are fragile. Id rather blow a Ramps or Arduino to learn that lesson the cheaper way rather than blowing a Smoothie for example, but that said, a Smoothie is more robust. For a P3 Steel ramps will do for now.

If you want a good board, my advice is not to use Arduino/RAMPS at all, because it has too many disadvantages e.g. slow USB-over-serial connection without flow control, tricky stepper motor current adjustment, no SD card unless you add an LCD, fragile voltage regulator, 12V power limitation, and poor performance (although sufficient for a Cartesian printer). Choose Duet or Smoothieboard instead. If you can't afford those, then there is little to choose between different RAMPS boards because there is very little on the board besides a pile of connectors. OTOH it is worth spending a little more for good quality driver modules constructed on 4 layer boards, to allow more stepper motor current if you need it.

Motor current adjustment is a simple trim pot and multimeter, hardly tricky.

You can run from SD card without an LCD.

Never had a failed voltage regulator and I have 4-5 RAMPS boards.

You can buy a "RAMPS" board from RRD that supports up to 35v I believe, I know for sure you can run it at 24v.

Really no reason for someone new to not use RAMPS, it was the standard for a very long time and has a ton of documentation and firmware support.

You only need to read these forums to see that a great many people have trouble doing it. Some short the driver board out in the process.

Sure you can, if you can find an SD card addon separate from an LCD.

Again, read the forums, there are a lot of reports of failed voltage regulators.

Yes, but look at their prices! $59 for a board that is basically a pile of connectors and a few not-very-good mosfets. You still need to add the drivers and the Arduino (or Taurino if you want to run it for 24V) - and then you are spending more than a 32-bit boards costs.

It's old, out of date and high time it was retired in favour of something better, with a faster processor, native USB port, decent voltage regulator, and software control of stepper motor currents. Keep the plug-in drivers if you like, that and the fact you can pick up Arduino/RAMPS clones for very little are the only things going for it IMO.

if someone can't manage to turn a screw to set a voltage than maybe building their own printer isn't something they should be doing.

Why do you need a faster processor when RAMPS will do just fine for 90% of printers?

That's a rather contemptuous attitude. All sorts of people build repraps, some with a lot of mechanical experience and zero electronics experience. Software control is also much more convenient. I've just reduced an extruder stepper motor current to resolve a problem with the extruder chewing up filament. I'm glad I didn't have to remove the bed to access the controller and mess around with pots and multimeters.

The fact that the atmega2560 is more than double the price of a much more capable 32-bit processor (with around 8x the performance, 6x the RAM and a native USB port) tells me that Arduino/RAMPS is an obsolescent design.

Your whole argument for getting rid of RAMPS is it being old and not powerful enough..

...yet we have nothing new pushing firmwares to require Smoothie or other arm boards.

RAMPs/Arduino are NOT out of date. They are a reliable staple of RepRap. There is far more performance headroom in a Ramps/Arduino setup than people give credit for. Its all about setup.

In fact the degree of microstepping used on cart based machines is also debatable/excessive.

As for people blowing things up through adjustment - Often the easiest mistakes are the most common, in this case, fried electronics or drivers through rushing and forgetting often one small step, like using a ceramic or plastic screwdirver for adjustment of pots, or unplugging main power before doing this adjustment. And often for novices and learners the only way of learning these mistakes is a hit on the wallet and a few hours down time.

All my own machines have Ramps/Arduino (or 8 bit derivative) - Uploading firmware is easy as Pi and quick. In normal operation, i never need to reupload.
