Thats the reverse polarity protection diode D2 see reprap.org/wiki/File : D1D2.jpg (remove the spaces, silly editor keeps turning it into a smiley) the diode sacrifices itself when you plug in power backwards.

"uses a RAMPS board so I’m limited to 12v" well that false for a start, many use ramps on 24 volts. You just need to know what your doing. Basically if you want just a 24v bed, replace the 11amp poly fuse with a thick wire. And put a inline 24v fuse in the heated bed wire. Hook up 24v to the 11amp input. That is all there is to it. Now if you want full 24v conversion, steppers, hot end etcby Dust - General

unknown, but you cant get the mk2 bed or the probe they use anywhere. (unless you get a upgrade kit)by Dust - Prusa i3 and variants
@Lymphomaniac1 re firmware, you missed the point The Original Prusa mk2 has custom firmware, that only run on Rambo (unless someone wants to port it, and even then you lose the advanced features as ramps is just not capable of them) One of the feature that most people want is the auto alightment stuff, where by it uses Fiducial markers on the heated bed to work out the skew of the machineby Dust - Prusa i3 and variants

send a M119 at your printer to find out what status the controller thinks of your endstops Now manually test your endstops Move the printer axis so they are not touching the endstops Check M119 says everything is open Manually hold down a endstop, check the status with M119, repeat for each axis.

"Is the Arduino/Ramps combo interchangeable with the RAMBo board? Same code and everything?" No. Same CPU, different pins and rambo has additional hardware features, like software controlled current limiting, extra mosfets and software controlled microstepping (just enough to make porting a PITA, ramps support has been removed from the source) You would not be able to use the binary firmware prby Dust - Prusa i3 and variants
"but it's not working for the Y_MAX_POS, I changed it here also to 190 but the Y stays the same, seems not to react on this setting!" yip.. Your trying to adjust the position of the physical end stop. But on Y you have a minimum endstop, not a max In this case you need to home the y axis and measure from the tip of the nozzel to your Y0 location (at the front of the bed) while keeping the ruleby Dust - Firmware - Marlin
The Xmax endstop is set to be at a certain location, by default this is 200mm eg #define X_MAX_POS 200 This is probably not accurate what you need to do is home X to the right then measure from the tip of the nozzel to the X0 position with a mm(inches are useless here) ruler keeping the ruler parallel to the X axis. Enter this value into the above line in your configuration.hby Dust - Firmware - Marlin

The ramps is designed to take two different power supplies. as long as you wire it correctly (ie - +. - + on the connector, from the bottom) (many run 24v on the 11amp cct and 12 on the rest of it) The gnds are even wired together to ensure they are the same potential. I can only guess you wired it either - + + - or + - - + or it was just a bad power supply. either way its sounds like thby Dust - RAMPS Electronics
unless you have a really weird printer your naming your axis all wrong... For a 3d printer Z is up and down movement, z probes are also up and down. X is left and right Y is back and front so taking your "stops are for Z on the right side, Y in the back and for X I use auto bed leveling with servo." I presume you mean, X is on the right side, Y in the back and for Z I use auto bed leveling wiby Dust - Firmware - Marlin
Reversing could be X or Y axis reversed Identify your type of machine Identify where your end stops are On I3 the Bed moves in Y, Y is backwards from what you think. (remember movement is relative to the extruder) On I3 type machines Min end stops are at Left, Back and Down positions, if they are elsewhere they are maximum end stops Find in configuration.h the section on endstop directionsby Dust - Firmware - Marlin

"This used to work before I tried making longer cables between the 5x2 connectors and had a short between the pins" You have probably damaged the IO pins on the mega, the only fix is a new mega (unless you want to move it to new pins with board modifications and run custom firmware for those modifications)by Dust - RAMPS Electronics
This is a known issue The display connectors are the same, but some are 180 degrees out from others Ie you need to turn the cables around 180 degrees for the correct electrical connections, but you cant do this because the physical socket is keyed. Normally its not an issue, the screen is supplied with a ramps converter that also has its cables flipped 180 degrees If you look at the back of tby Dust - RAMPS Electronics

"1st: How do I set the firmware to match? where do I tell it that is NO?" Its not written that ways... you invert the logic of the endstops eg: // Mechanical endstop with COM to ground and NC to Signal uses "false" here (most common setup). #define X_MIN_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop. You say they endstops are working though, so no need to play with tby Dust - Prusa i3 and variants
firstly "I connected the end stop in the pin NO, because that was what the instruction said, but I found that many connected it with the NC pin. Maybe this is the problem?" It doesn’t actually matter as long as you sent the firmware to match. Most use NC as its less likely to falsely trigger and you notice if a wire come loose etc secondly follow the following to setup your axis and endstops coby Dust - Prusa i3 and variants
