Makerbot MightyBoard Rev H for the Replicator 2/2x

This 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!

Gday mate. Im not sure if your offer is still available, but i have a replicator 2 Rev-H Mighty Board that was damaged in a lightning strike. I suspect that its the first capacitor after the switch that has blown (going off the carbon trails around the switch). After it broke i bought a Geetech board, but i would prefer to continue using the original if at all possible.

would you be willing to have a crack at repairing it? everything else on the printer is fine. i think even the ramps are fine. so i should only need the mighty board repaired.

thanks mate. let me know what you think when you can.

I could take a crack at it. No pun intended since it got hit by lightning… LOL

The only concern is from my experience lightning damaged stuff sometimes ends up being a troubleshooting marathon, and parts that don’t appear damaged might actually be damaged or fail after getting power back to them the first time. But you won’t know that until you try. Drop me an email direct and we can discuss it further., i’ve been busy repairing a batch of printers lately so i haven’t had much time to get on the forums, but i always check my email daily.

Do you have any mighty boards left that are avaliable for sale?
I have a makerbot replicator 2x that has a display with only back light and won’t run.
I’ve swapped a diplay from my working makerbot replicator 2 to my broken unit and I get the same result. This leads me to belive it’s the board.

Thank you for your time.

no but

That was my listing on eBay and the last board i had available for sale at this time. it just sold today.

I do still repair them of course though, and judging by your description of your problem i can certainly repair it. Just let me know and we can work out the details!

I have been doing a steady business of repairing these boards this year, its amazing how many of them are dying.

Sorry for the late reply.
That sounds fantastic! do you have a ballpark estimate on cost to repair the board?
Do you need the 5 chips included on the board when I ship it to you?

Thank you for your time.

Sorry for the late reply, i don’t always get the notifications from the 3dhubs forum in my primary email.

Send me an email and we can discuss in better detail what it would cost to repair your board!

Do you have any more available, I have rev h board that needs to be repaired…

I don’t currently have any boards on hand, but i do still repair them, and i have been repairing a lot of them lately so i have parts in stock.

If you need one repaired send me an email, note my email has changed since some of my earlier posts, i tried to edit them all but it won’t let me.


I have a blown PCB Display board on a Makerbox 2x. I can begin prints with the usb, but the prints always fail. Machine freezes and I hear a long tone that requires me to turn off the machine. This makes me think that the Mightyboard is bad as well. Can you give any suggestions as to whether I should try repairing or replacing?

I have a makerbot Rep2 Rev H board that I think has popped. It powered on ok twice then the third time no chimes and no display. The board is getting power it lights up green but nothing else fires up.

You still doing repairs, if so how much?
