Mar 7, 2022 at 15:26 comment added Greenonline @Navin - good catch, that should probably be "maximum output". I hadn't noticed that.
Mar 2, 2022 at 11:23 comment added Navin “maximum input for current” doesn’t make sense. You could connect the board to a 10000A power supply, but the board will only draw ~12A. Also RAMPS is ancient tech.

Feb 14, 2022 at 14:27 comment added 0scar Furthermore, this question should be reworded, instead of focusing on the RAMPS 1.x board differences, you should focus on the real question where you are interested in: "How to get more power from a board than they are rated for?" or "The current required for my printer exceed the current ratings of my controller board, how can I mitigate this?".
Feb 14, 2022 at 6:13 comment added 0scar P.S. RAMPS shields on top of AtMega Arduino boards are pretty outdated, they will work, but there are plenty of other boards available to choose from. You should look into 32-bit microprocessor boards.
Feb 13, 2022 at 7:08 comment added 0scar I guess the heated bed is the main power consumer here, if this is drawing more than 10 A you definitely need to insert an external MOSFET, these are cheap external modules that can handle even larger currents than the board itself. Found easily on those typical online market places.
