    I swapped out my Rev E board from Makerbot with this Board. While I'm able to navigate the menu and heat up the extruders, I do not appear to be able to drive the stepper motors. I'm using the same stepper motor drivers that came with the maker bot that were on the Rev E board. Is there something I need to do to get them working properly. If not, I'd like a refund.

    Hi i bought a board like this, but cannot get the stepper motors to work. I am using default makerbot stepper modules. Botstep 17. Would this board work with regular A4988 stepper modules? or does it require a special kind of stepper board?

    • Quentin Qiu | 01/19/2016

      Hi, A4988 is OK.

    Installed board and everything worked as planned (I am have not been able to get the second extruder working but that is another problem) The problem I am having is when running the table level program. When the table goes to move to the first position it hits both the Y-axis and X-Axis hard-stops. I suspect the software is set up for micro-stepping while the driver is set up for full steps? Is there a way to check this?

    I bought this board, but I'm having problems flashing the firmware with RepG. Is there a way to check if the bootloader was installed correctly? The manual does not mention the need to press the reset button, but with or without pressing it's not working. I remember with the original makerbot board to also have big problems flashing, but it did work there in the end.

    • Quentin Qiu | 09/24/2015

      Hello Maria, you can do as the followings:1.connect the bare board to PC and check if the device manager could detect the port. If not, install USB driver. 2.If the port could be detected, you can burn the firmware by referring to this link: http://www.geeetech.com/wiki/index.php/Mighty_Board#File_Burning 3.If some errors occur when you burn the firmware, there should be an error warning display. If this kind of situation happens, please take a screenshot and send it to me.

        A friend at the local fablab looked at the board. He found a faulty oscilator crystal on it. Fortunately the crystal on the revE board this revG has to replace (the revE blew up in typical Makerbot fashion) was functioning, so we could replace it. After that, flashing worked without problems. So it was a hardware issue.

  • Eric Lin | 07/17/2015

    Is this board can perfectly match on the Makerbot Replicator 2 printer? If it could.....what are the other driver ic I shell buy also Please help , Im really a beginner, but I just broke it Q_Q

    • Quentin Qiu | 08/30/2015

      Hello Eric, this board can be used on this type of printer,for the stepper motor driver module you can choose A4988 or DRV8825 motor drive IC
