Makerbot Replicator 2/2X MightyBoards! Rev H

FOR SALE!! Makerbot MightyBoard Rev H for the Replicator 2/2xThis board has been fully tested as working, drop in replacement. Note:  I have been getting some questions on these, if you have a Rev G board you CAN swap with a Rev H board, HOWEVER, the difference is the power connector.  The Rev G board has a female socket and the plug is a male, on the Rev H the socket is the male and the power adapter plug is a female.  I have swapped these before to fix printers and it works no problem other then the power connector!  If you have a Rev G thats dead and need a replacement you can replace the connector on the board, or i can do it, but inquire first as i have a limited number of female jacks for doing this! The following tests were performed in a Replicator 2x. 1. Preheat Bed and Both Extruders, Fans on extruders cycle on and off at 50c as they should, maintains temperature.2. Unload and Load filament on both Extruders.3. Jog X, Y, Z back and forth between both extremes of movement, checking full movement and Endstop functions.4. Print from SD Card, 1 hour test print to verify function of all aspects of the board.5. Connected to USB and Simplify3D and checked for control and print from USB. This is a fully functional and ready to swap in board if yours is damaged.  Due to the nature of these devices and the potential for damage if improperly installed or connected this is a no returns sale.  The board has been fully tested to insure it functions correctly before shipment. I have them available with or without Botsteps installed.   


 $175 for with Botsteps, $150 for without.  Multiple boards are available, all of them have been tested and repaired as necessary and thoroughly tested again.  If you have been looking to repair a 2 or 2x or just want a spare handy heres your chance to get some at a fair price. I also have some spare Carrier PCB's for the front panel, if your SD card slot has stopped working i have replacements, no need to replace the entire display unit from Makerbot when you can just swap the board.  I also repair these boards if you want one repaired!  $50 each for the Carrier PCB. I repair MightyBoards!

G'Day

Where are you based? I have a school MakerBot that had the power plug jammed in upside down (Rev H) and wondered if the board can be repaired, and if so for how much. The 24V LED lights up on power, but nothing else at all happens. The fuse is still good. Checked it first ;-)

I'm in Melbourne.

Cheers

I am in the USA.  I have dealt with a few that the power plug got jammed in upside down, which causes reverse polarity to everything, but generally it just blows up U1, the A4403 Buck Regulator, which is why you don't have 5v and the board won't boot.  Sadly they didn't add reverse polarity protection on the input after the fuse, so the fuse won't pop and save it when it gets reversed, i think they figured nobody would be able to with the power plug they used, but as you found out it is possible!!  The A4403 is pretty cheap, a couple bucks, but in some cases i have also seen this problem pop the capacitors associated with that component.  They are a bugger to replace because its such a small SMD part and it has a center pad for heat dissipation under it, so the board wicks away the heat pretty fast while your trying to remove it.  However i have repaired this problem multiple times and it is possible to do it.  Being that your in Melbourne though the shipping both ways plus labor might be pretty expensive for you.  I generally charge a flat rate of $50USD for general board repair plus the cost of components and return shipping.  If you want to discuss it further drop me an email, crazyhamsales@mediacombb.net and we can see what i can do in regards to shipping costs etc.

 

They must have really worked hard at that power plug, takes quite a bit of force to jam it in upside down!

I could ship to Italy, however, i am out of stock on working boards.  I will extend my repair service to your existing boards if you wanted to ship them over for repair?

The most compatible that i know of is the Geeetech Rev G board, its a combination of the Rev E from the Rep 1 and the Rev G from the Rep 2, they used the same connector location layout but went to the switching regulator of the later Rev G version to prevent blowing up the 5v regulator.

 

The only bad part is that you will have to take your original Rev E board and salvage all the connectors off it unless you want to chop all your wiring plugs off, because they went with screw terminals for everything instead of connectors and headers like Makerbot did.  Usually what i do to replace a Rev E board is get the Geeetech board and desolder and replace all the jacks with the ones from the dead Rev E board.  Most importantly though is the power input jack, they soldered a screw terminal into that place, but the stock connector jack will go in its place as the board layout is correct for it.

This thermocoupler is manufactured in Australia to higher specifications than the Makerbout out of the box thermocoupler that comes with the Makerbot Replicator 2 and 2X Our Thermocoupler is made of thicker stronger wire, it has stronger kapton sheathing and is resin reinforced at the sensor.

@CrazyHamSales Do you repair FlashForge Creator Pro boards? They are almost identical but slightly different.

I havent had my hands on one yet, but i certainly could try, from what i can see from pictures online they aren't much different then the original FlashForge boards that i have worked on.

 

Whats wrong with the one you have?

The extruder ports, where the wires connect to the board are bad.

Is it just the connectors that are bad or?  If you can send me a picture of it i can see if i have or can get parts for it.
