    So let’s say you get a 1.6 version board. Note that there is no longer a 4-wire connector for the power supply. So how is this connected on the new board, I.e;

    1. Do you connect the two positive wires together (and the two negatives) and secure them into new connector, or;
    2. Only run one pair from the PS to the RAMPS? If so, which?

    You should be able to tie them together. The reason for the other setup was more wire could carry more current as the ribbon cable isn't very large gauge wire.

    Yea, the standard 1.4 RAMPS is split with an 11 amp circuit and a 5 amp circuit. The 1.6 version is combined (but still less).
    I am not really a fan of the 1.6 boards, most are (as difficult as it may be to comprehend) even worse quality than the $10 RAMPS 1.4 boards :) Still -- if you have it, try it.

    So I completed my installation of the RAMPS 1.6 and much to my dismay, the printer won't power on. When I plug the USB cable into the Mega, a blue LED momentary appears on the RAMPS, but the PS fan isn't running. I wonder if joining the 11a and 5a (red to red, black to black, of course) caused a problem. I lost my patience and just went upstairs, thinking it's time to buy another printer, sigh...

    When I get home from work today, I'm going to check the AC socket fuse and then my power connections to the RAMPS board. The connectors kinda suck. I hate to give up on this printer, especially because my wife gave it to me as a gift three-ish years ago. That and I've modified the hot end/extruder and the thing was dialed in just right. It worked great until the RAMPS died.

    The power supply is probably two rails (not one) so that may be the issue or ... it could be a bad RAMPS*. I really am not a fan of any of the RAMPS 1.6 boards I played with and I don't use them in any printers.



    *and that is not limited to the 1.6 boards, they are all so cheap that nobody apparently does any QA on them. I have gone through as many as 3 bad (but new) boards at a time to get one that worked. See if the Arduino board is overheating with the RAMPS connected (and powered on). That is a sure sign that the RAMPS is bad.

    Hey guys, thank you everyone who has contributed to this! This helped me a ton, just replaced the board with a generic RAMPS 1.4 board this morning since my bed wasn't heating up anymore, and it works!

    I do have a strange issue now though, well, not so much an "issue", but my X-axis and extruder steppers seem to be making a lot more noise now than they were before. My prints are coming out beautifully so it's not necessarily a problem, just an annoyance. Any thoughts?

    Maybe post a video showing what you mean ? It’s possible your new drivers (assuming installed new) are giving more current (no big deal if your not skipping steps). Could also be your large gear has come loose a little and could be snugged up some ? If all is working I’d just rock it :)

    Ahh good call sir, I meant to move the drivers over to the new RAMPS board but totally forgot as the replacement board already had them installed. I'll have to swap those over and try again. Thank you for the quick response!

    I have two robo R1+ my first one I've had for a couple years and after a year of use the heated bed stopped working so I replaced the ramps board and all is well. I picked up a second r1+ that was used and the heat bed wasn't heating, I replaced the ramps board. Everything seems to function properly, except it extrudes about twice the speed that it should now. Having a hard time figuring out what I messed up with the install.

    Any thoughts?

    Double check you have the jumpers installed for the stepper drivers

    Bingo -- the extruder output stepper driver is probably missing some or all of the jumpers underneath it.

    That was it! I read the instructions wrong when it said to jumper 3 of 3. When i needed to jumper the 4th of 3 for the extruder driver. I did a quick 15 minute print and it came out pretty close. I'll need to make some tweaks to the settings and should be good.

    Thanks for the help!
