Perfecto.

Niveau prix c'est super, niveau électronique les composants sont fragile, voir qualité chinoise.Carte cramé en moins de 3 jours sans mauvaise manip

Ottimo prodotto ad un prezzo eccezionale, funziona tutto alla perfezione. Il controllore arduino mega non è originale ma compatibile, un pò corto il cavo seriale usb per la programmazione della scheda, ma ciò non mi ha creato problemi. Consigliato

Missing two parts actually but I upgraded to 4 stars based on recent success after getting those...I contacted the seller and they quickly offered to send replacements for the missing terminal block and jumpers. Overall excellent customer service. I opted to order replacement parts from Amazon instead of wait for the parts or return the whole set for a replacement because I already had the board mounted and I needed to get running early the next week. I was able to get everything configured full step while waiting on the jumpers. It worked fine but was REALLY loud and was lacking torque in the motors. I had the current already set for my motors and opted not to try to turn that up any more. Once the jumpers arrived I set it for 1/16 steps and changed the code in the configuration.h and it has happily been running for about 2 days non-stop. I have printed items as small as a pencil eraser and as large as a 6 hour print. All in all it runs better and has better print quality than the integrated board I was using and if a driver blows I can just replace it for $3.Update:Oh yeah, the screen is dim if only powered through USB but looks great when you get 12V on the RAMPs board.I would have given it 5 stars if I didn't have to wait for replacement terminal strip plug and jumpers.Original 3 Star Review...Missing one part...Everything arrived in good shape except I am missing the green terminal block that plugs into the power block on the ramps board. I can't hook my printer up until I have that.I just received mine. It was well packed. The boards were plugged into anti static foam place inside anti static bags, inside a box wrapped in bubble bags inside another box.In the mean time I connected the boards and the drivers and uploaded Marlin with my printer dimensions and other settings. The Arduino IDE connected just fine with no additional ftdi drivers or antythimg needed and the program uploaded great. The screen is very dim even with the contrast pot turned all the way left. It also does not seem to respond to contrast adjustments in the menus of in the configuration.h. It's readable but dim.Update:This board is pretty tough. Halloween is coming so we have been printing Fallout stuff for my boys almost nonstop since I got this. Longest print so far is about 7.5 hours for part of a combat shotgun. We have printed the shotgun, a 10mm pistol a complete T45 helmet and several other things. It runs all day as fast as the kids can remove and restart and then usually we go to bed with it running (away from everything, near us with fire/smoke detectors, etc). So far the control board has been flawless. I didn't tighten the screw enough on one of the heating elements and it popped out of the hole. The smoke detector went off although I was sitting about 3 feet from it and had already smelled it. By the time I got to the printer the heating element was glowing fire red. I let it cool down, swapped heating elements and fired it back up. So far it's printed maybe 30 hours with no ill effects to the board since that happened. That would have blown my old all in one board to pieces. I know because it blew outputs when the thermistor varied too much. Anyway. This seems like a really tough board.

Very good set, I tested everything, but i could not find out how to upload the filmware, but the seller wanted to help and helped me alot with finding this out, I realy should recomend this to anyone who is looking for an good but low price ramps board!

Increible la oferta y la calidad de este producto. Lo compre para la cyclone cnc y en un mismo pack venia todo lo necesario

Great kit! If you're scratch building a reprap (like a Prusa i3) this works a treat. As is the rule with any inexpensive Mega Clone / Ramps Clone kit, expect a little fiddling when it comes to getting the pins to line up. Documentation for wiring can be found at ReRap.org. Be sure to put your jumpers under the stepsticks! Check out Thomas Sanladerer's guide on YouTube ("Setting up a LCD and SD card controller panel") for how to get the display to work. I didn't do any adjustments to the pots on the stepsticks and all my steppers run awesome, so that was nice (though your mileage may vary). I used this kit with these steppers: https://www.amazon.com/gp/product/B00QEXSCE8/ref=oh_aui_detailpage_o05_s04?ie=UTF8&psc=12018 Update:- The RAMPS board in this kit is a Robotale brand board- The MOSFETS on mine are IRF3205Still using this board and printing every day practically - and for the price, I'd still recommend it. I gave it 5 stars for "what it is" - a cheapo import RAMPS kit. I've bought and used few more of this exact kit over the years in other builds and have had good luck with them. I've gotten a lot of other competing kits too, and I'd call this one the "least dangerous" one I've found. Be careful though: these are built to a price point. Do your research first on what to look for when inspecting a RAMPS board. In addition to the normal bent headers and the like, I've seen cut component legs bridging connections, cold solder joints etc. The power input connector is typically unlabeled, so no idea what the rating is, but I've not had one fry on me yet. The output headers for the bed and accessories on all the kits I've gotten have been 10A, which is under spec, but again I've never had one fry. I've read some of these come with 16A headers, but mine haven't. If you want to be safe, replace those with quality 15A on the input and 16A on the output to be safe (you can find both here on Amazon). The MOSFETS on all mine have been IRF3205 (including the bed). Even if they actually meet spec, those are a little marginal for the bed, and they do indeed get too hot to touch under load. Plan on adding your own heatsinks or upgrading at least the bed to an IRLB3034PBF or one of the other popular upgrades. Cheap insurance. And though mine have all come configured correctly, I would recommend checking the Vref on the stepsticks.I should also mention: in every one of these (this particular kit) that I've bought the LCD has worked, the SD reader has worked, and all the stepsticks have worked. For under $40, that is a pretty good deal. As to the bent headers, cold solder joints and stuff, yeah: ALL the cheapo ramps boards are like that. All of them. There is not a quality RAMPS board on Amazon that I know of. But there ARE a lot of boards/kits on here that are more garbage than this one. No matter WHAT board you get, inspect it and plan on doing a little work. You're a Maker, after all!Upgraded output headers: (ignore the reviews about the compatibility with the 2 terminal version - it doesn't affect this use since you're using two three terminal): https://www.amazon.com/gp/product/B015VY0OF0/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1Upgraded Power Input: https://www.amazon.com/gp/product/B00QC6QS5W/ref=oh_aui_search_detailpage?ie=UTF8&psc=1Upgraded bed MOSFET: https://www.amazon.com/gp/product/B00HKHW9UU/ref=od_aui_detailpages00?ie=UTF8&psc=1Also, if you are interested in learning more about the RAMPS architecture and component selection for it check out the videos by Alex Kenis.

Good price! The only item with an issue was the ramps 1.4a board that had some pins not seated well enough to line up with the arduino, and one pin was not in contact with the pc board (that pin failed a continuity check). The misaligned pins were easy enough to put in position and a minute with a soldering iron fixed the nonconnected pin. The driver boards all worked fine (they came with stick-on heatsinks) and the lcd display was fine with no scratches from the other items. It took a little longer to arrive than the 2 day prime indicated but that could have been amazon. All in all I am quite happy with the package and would buy this again. Remember that no instructions are provided, but can easily be found on the internet.
