Can I connect a PSU with a higher current rating than RAMPS 1.4 can handle?

Voltage and current behave differently and it is important to remember two essential points: PSU voltage specifications should never be exceeded, else the circuit will (most likely) be damaged, and; ...

Can I connect a PSU with a higher current rating than RAMPS 1.4 can handle?

Yes you can connect that PSU to the RAMPS 1.4 shield, and no, it will not burn the shield under normal operation (too much and/or too high current draining peripherals attached or shorting of circuits)...

Arduino Mega 2560 + RAMPS voltage on GPIO pin

Connecting a 100 Ohm resistor is definitely not safe. This load is far too high for an AtMega2560 output pin. 100 Ohms at 5 V (when the pin is high) is 50 mA, whereas the ...

Short circuit on RAMPS 1.6 board?

Your multimeter showing continuity doesn't necessarily mean there is a short. All your multimeter is doing is applying a small voltage and then, if the current that flows is over a certain threshold, ...

Closed-loop stepper motors

A number of options exist, but keep in mind that cost will be a limiting factor. (Small sidenote: cost depends on persective, financial cost does not equal mental cost. The tradeoff between buy or ...

Replacing RAMPS 1.4 for 1.6

RAMPS 1.6 is very similar to RAMPS 1.4. Most, if not all, of the changes are hardware improvements, without making the core functionality different. Looking at the incremental changes between versions:...

Some steppers only rotate one way on RAMPS 1.4

As towe said, it could be a dir pin ( can be checked by metering the dir connection), but in my experience this behavior has usually been a limit switch issue (as 0scar pointed out). Try seeing if ...
