Jumpers enable microsteping and make movement smooth and quiet You want all 3 jumpers on it to enable 1/16 microstepping. It follows his table Where in this case high = jumper in place, and low = no jumperby Dust - RAMPS Electronics

That voltage regulator is toast! You need that to convert from 12v to 5v... so if your happy to power it from usb, it will work fine (5v comes over usb cable). Just remove d1 from the ramps so it doesn’t attempt provide power to the mega. If you want to print computer less, you have no option but to replace the regulator, or the whole mega.by Dust - RAMPS Electronics

The voltage listed on the steppers is normaly just the current * resitance you have said the current is 2.43 and the resitance is 1.5 ie V = 2.43 * 1.5 = 3.645 volts This makes more sense. as you can drive that from a 24v supply no issues. So driving this form a drv8825 stepper driver should be fine (even if a little curent limited)by Dust - General

24v is not and issue on standard RAMPS It you know what your doing... The caps C3, C4, C6, C7, C9, C10 - 100uF capacitor on the board need to be 35v not the cheaper 16v The mega is powered from the 12v via D1, for 24v D1 must be removed and the mega powered vi another way (its own power plug for eg) and the 11amp poly fuse need replaced its only rated for 16v BUT The standard pololus wilby Dust - General

Should work fine You will need to add additional board files into the IDE to know about the board, but this is not a issue. Is documented hereby Dust - Controllers
doing that generally puts 12v onto 5v lines... this tends to make all 5v thing very unhappy.. Sorry to say it new mega time.

A lot of these issues will be due to absolute crap filament. If you pay bottom dollar, you pay for it in other ways. I've seen many a person struggling to print, you give them some known decent filament and they are printing in minutes! The second most common cause is crappy hot ends from e-bay or aliexpress. All I can say is get your hot end from a reputable supplier if you don't want a "by Dust - General
This is because its the power supply not the reprap side If the power supply wont start up via the green wire its either dead or over loaded. Unplug everything try again. But I suspect you just need a new power supply.by Dust - Reprappers
Stigern, the mega is only rated to 12v so if you powering the mega from the ramps via D1. 12 volts. Some have gone as high at 19 without frying things. but I cant recommend this. Your generating 5v from this, so you if applying 19v it have to turn 14v into heat! 12.2v is no issue from "The board can operate on an external supply of 6 to 20 volts.

most have a configuration.h which has many many many setting for your printer.

I personally recommend linux for reprap. Stops issues like Microsoft randomly rebooting your pc to apply updates at 3am, even though you have set it to not apply updates... but thats just my preference. Most reprap software is platform independent. It will run on any common OS And a ftdi driver is available for common os'sby Dust - Controllers
