Arduino 2650 blew up... with RAMPS 1.4 hi, today when i tried connecting an USB cable to the Arduino while still powered by the RAMPS 1.4 board... the arduino just fried its power regulator chip next to the power socket. tried with another arduino board using the same RAMPS 1.4 board and even this got fried.... wondering what is happening? inputs highly appreciated... https://reprap.org/forum/read.php?1,735074,735074#msg-735074 Mon, 10 Aug 2026 16:34:47 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,735074,768737#msg-768737 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,768737#msg-768737

You can still kill a duet wifi card, but there is a lot more thought put into making that harder to do...

Watch this space, I have a video on How Not To Treat Your 3D Printer Electronics nearly ready for release!]]> dc42 General Thu, 18 May 2017 10:37:01 -0400 https://reprap.org/forum/read.php?1,735074,768688#msg-768688 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,768688#msg-768688
Stage 1 - I want to play around with building/owning a 3D printer - I am not sure its for me yet. I want to do this at low cost. So use ramps and mega, if you fry your mega, repair it or buy a new one they cost £10 at most (probably less).

Stage 2 - I have been 3D printing for a while and now what I want is high quality, or high speed (or both B)) at this stage I am not adverse to spending some money, as you don't get amazing for cheap. Buy a 32 bit controller, and I am biased as I now have 2 Duet Wifi cards, they are very, very good and its an active firmware things are developing really well, and really responsively to users needs.

You can still kill a duet wifi card, but there is a lot more thought put into making that harder to do, and you are going to be more careful it cost you 10 times more than your ramps board.]]> DjDemonD General Thu, 18 May 2017 05:59:42 -0400 https://reprap.org/forum/read.php?1,735074,768683#msg-768683 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,768683#msg-768683 robbycandra General Thu, 18 May 2017 05:36:51 -0400 https://reprap.org/forum/read.php?1,735074,736454#msg-736454 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,736454#msg-736454
Another thing people like about Duets is the web interface, which can be used from a PC, smartphone or tablet - or all 3 at once. See [reprap.org] for pictures and more info. We recently added visualisation of the bed height map to the web interface too.]]> dc42 General Sat, 07 Jan 2017 11:54:03 -0500 https://reprap.org/forum/read.php?1,735074,736395#msg-736395 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,736395#msg-736395 JamesK General Sat, 07 Jan 2017 08:02:21 -0500 https://reprap.org/forum/read.php?1,735074,736336#msg-736336 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,736336#msg-736336

i am sure ready for a better board... could you suggest some?

Duet Wifi. I'm biased because I helped to design it, but you won't find a better board. 32-bit, easy firmware configuration using a text file on the SD card (no need to recompile and re-upload the firmware), up to 256x microstepping (which makes the motors very quiet), fully functional web interface - including fast upload of gcode files to the SD card, configuration file editor and firmware updating. And of course software control of stepper motor currents. The only time I wouldn't recommend it is if WiFi is not suitable for you for some reason. In that case you could use the Duet 0.8.5, or wait a couple of months for the Duet Ethernet.

Amongst the 8-bit boards, the best ones IMO are the RAMBO and RAMBO Mini. But they don't provide the easy firmware configuration, high microstepping drivers, or the web interface.]]> dc42 General Sat, 07 Jan 2017 02:53:23 -0500 https://reprap.org/forum/read.php?1,735074,736324#msg-736324 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,736324#msg-736324 saintofinternet General Sat, 07 Jan 2017 00:07:44 -0500 https://reprap.org/forum/read.php?1,735074,736266#msg-736266 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,736266#msg-736266

RAMPS strikes again!

Amazing we don't have anything better yet.

We have lots of controller boards that are better than Arduino/RAMPS. But most are manufactured to much better quality standards, and the best ones help fund their developers so that they can go on making improvements and develop the next generation. So they cost more than RAMPS. Sadly, most of the kit manufacturers and many home-build users choose the cheapest electronics they can find.

Arduino/RAMPS may be unique in that shorting Vcc to ground by mis-wiring an endstop switch blows the voltage regulator. The controller boards that I am associated with are designed to withstand this and several other common wiring faults.]]> dc42 General Fri, 06 Jan 2017 16:38:59 -0500 https://reprap.org/forum/read.php?1,735074,736128#msg-736128 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,736128#msg-736128

There are several better' choices for printer control boards if you're willing to pay the money, or did you mean specifically a different adapter board for arduino? It is a shame that we don't have a good ramps-like adapter for the STM32 family of development boards, although I guess we could just use their reference design.]]> JamesK General Fri, 06 Jan 2017 07:05:45 -0500 https://reprap.org/forum/read.php?1,735074,736124#msg-736124 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,736124#msg-736124

it was the X Axis endstop which was faulty... and when plugged it shorted the Arduino...

replaced the endstop and now it's started working.

long way to go...

do we have any ready deployable Prusa i3 firmware ready to be downloaded and flashed??

thanks to all you guys for the excellent support....]]> saintofinternet General Thu, 05 Jan 2017 22:34:19 -0500 https://reprap.org/forum/read.php?1,735074,736052#msg-736052 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,736052#msg-736052 epicepee General Thu, 05 Jan 2017 22:14:47 -0500 https://reprap.org/forum/read.php?1,735074,735298#msg-735298 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,735298#msg-735298
It's unusual to blow the regulator on the arduino with a ground loop problem, so I'm not sure that this is what you have, but it's also unusual for an endstop issue to have anything to do with the usb cable.]]> JamesK General Tue, 03 Jan 2017 13:16:26 -0500 https://reprap.org/forum/read.php?1,735074,735119#msg-735119 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,735119#msg-735119
will photograph it once i get the new replacement.

i am still worried what if it happens again... this time there will be no replacement :-)]]> saintofinternet General Tue, 03 Jan 2017 03:59:02 -0500 https://reprap.org/forum/read.php?1,735074,735100#msg-735100 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,735100#msg-735100
Plugged in correctly the Signal pin is connected to GND or +5v via the switch

Plugged in backwards however the +5v is connected to GND or signal. When 5v is connected to ground this draws to much current and will kill the voltage regulator

Ie since the ramps endstops pins has no keys, some people plug them in backwards


The next likely culprit is stepper drivers in backwards..

A picture of your controller and how its wired would help out a lot here.]]> Dust General Tue, 03 Jan 2017 03:07:55 -0500 https://reprap.org/forum/read.php?1,735074,735077#msg-735077 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,735077#msg-735077
this is the first time i am assembling a 3d printer...

can you please explain by what is "plugging 3 wire end stops in backwards" means?

all my mechanical end stops are having 3 wires... Positive-Negative-Signal and the RAMPS1.4 board has pins coloured in RED-BLACK-BLUE.

the connectors are plugged in proper sequence.]]> saintofinternet General Tue, 03 Jan 2017 01:20:34 -0500 https://reprap.org/forum/read.php?1,735074,735076#msg-735076 Re: Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,735076#msg-735076
you have a short or something plugged in backwards

Plugging 3 wire endstops in backwards will blow this nearly everytime.]]> Dust General Tue, 03 Jan 2017 01:10:43 -0500 https://reprap.org/forum/read.php?1,735074,735074#msg-735074 Arduino 2650 blew up... with RAMPS 1.4 https://reprap.org/forum/read.php?1,735074,735074#msg-735074
