Crap.. the ramps looks done…January 29, 2017 at 6:08 pm #26255
You seem to only have compete kits on your site. Can you link an amazon one you trust?January 29, 2017 at 6:09 pm #26256
nah thats the x plug, just ugly soldering.January 29, 2017 at 6:13 pm #26257
I haven’t bought any from amazon. Most should be fine though. I think most of the complaints about them are BS, but you never know.
I have a hot air soldering station due to arrive so I can do some repairs. I have a ton of 5v regulator fried megas that need a quick fix. but I’m sure it will be a while before I have any refurbs ready to sell.January 29, 2017 at 6:19 pm #26259
It looked fine before I did that. When I mounted it I had to split it to put the screws in.
So it’s the blue board? IF so I’ll just purchase a new kit from your store. How can I be sure?January 29, 2017 at 6:58 pm #26263
When plugged into my pc, it goes right back the way it was when I plug it back into the printer’s power supply.January 29, 2017 at 6:59 pm #26264
It works now?January 29, 2017 at 7:00 pm #26266
only on the pc, over usb. When I hook it back up the the power supply it doesn’t again.January 29, 2017 at 7:02 pm #26267
so maybe it’s the 5v regulator….the small black component near the power plug on the blue board. looks for a tiny burnt hole in the top.January 29, 2017 at 7:08 pm #26268
looks clean to me.January 29, 2017 at 7:17 pm #26269
Does it all work without the lcd? Through Repetier?January 29, 2017 at 7:21 pm #26270
I haven’t tried that yet.January 29, 2017 at 8:05 pm #26271
Cant get it to work, Unless i use only usb, It will tell me it hit a stop. If I plug it into the wall it tells me com 3 does not exist.
I’m just going to order a new set up. And a new driver just incase, as the extra one I ordered for the extruder got up and walked away…January 30, 2017 at 7:10 pm #26377
The Arduino can get power several ways. Either through the USB, or by the 12V. If it’s from the 12V, then it has to go through that 5V regulator. There is also a diode (D1, is how it’s labelled, I think) that connects the 12V to the regulator. There is another place where you can connect up 5V, on the ramps board, but you’d need another reduglator to get the 12V to 5V. It’s labelled Vcc and it’s near the X1 driver.
But honestly, even if you figure everything out to get it working, I’d order another. It’s just going to get blamed for everything until you replace it. If there’s a microcenter near you, they have the knock off megas for like $10.January 30, 2017 at 7:19 pm #26379
Microcenter even has the ramps boards.January 30, 2017 at 7:26 pm #26381
The ramps (or maybe it was the drivers) were crazy expensive though.January 31, 2017 at 3:17 am #26392
Thanks for the advice, but to keep things simple i ordered another on from the shop here. Id rather pay a bit more and have everything i need incase something else got messed up too. At least ill know for sure. If the ramps is still good ill use it on my second printer or mpcnc. I’ll find a usb powered project for the busted Arduino.February 2, 2017 at 4:21 pm #26548
Can anyone help me with loading the MP3dp firmware?
I’m getting this error when I try,
Arduino: 1.8.1 (Windows Store 22.214.171.124) (Windows 10), Board: “Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)”

your missing the file that is linked in your error message. Then you need to install it into your arduino libraryFebruary 2, 2017 at 6:10 pm #26557
Looks great man. Very glad to see those parts in action! Like others have said, I think the 5v reg on the mega went south. Been there myself. Cant wait for more progress.February 2, 2017 at 6:31 pm #26558
Thanks for your help man, I don’t think I could have done it with out you. I got the new board into day, I just got the firmware loaded, Got my bed on. Now I just need to make sure I wire the stops right, I’d looked up another diagram but the ones I followed had me wire the steppers up backwards, so I don’t know what to trust right now. Messing with the stops is what caused my board to fry in the first place.February 2, 2017 at 7:08 pm #26561
Signal and ground, no power!
Wired to the NC (normally closed) terminals of the switches.February 3, 2017 at 12:48 pm #26609
Well I hit another snag, The extruder motor won’t work when it’s plugged in the extruder #1 on the ramps. I’ve moved both the drive and motor over the the x plugs to make sure neither was at fault and they both worked there. Any ideas?February 3, 2017 at 1:03 pm #26612
Extruder motor won’t turn if extruder is not up to proper temperature.February 3, 2017 at 1:37 pm #26617
Yeah, after eating I did a search and figured out that it won’t allow that. So I got the hot end wired and it’s working like it should. Just to extend some fan wires now and good to go.
Plus some cable management, which I’m sure i’ll spend the rest of the night doing. lol.February 3, 2017 at 2:24 pm #26625
Okay guys, One more question, Where do i plug the fans in? I’m looking around the net but it’s all over the place.February 3, 2017 at 2:35 pm #26626February 3, 2017 at 4:22 pm #26635
I didn’t like connecting mine to the green input power (but I’m probably paranoid). I just worry it will somehow dislodge those larger cables, but crazy aside, there is also power on the second extruder connection, which normally powers the stepper driver.
The green connection or to the PSU is probably the easiest though.February 3, 2017 at 4:47 pm #26637
Yeah, it seems fine.
I got it printing! But i need to bed level a bit better and this thing kind of stinks.
Anyone else notice that smell? No its not my filiament.February 3, 2017 at 6:08 pm #26641
Maybe fish tacos smell…
