Customer Question

Arduino: 3D Printing: RUMBA Board: Mac OS X 10.11.5: I just replaced my Geeetech GT2560 board with a RUMBA board. I cannot get the Arduino IDe to connect and upload my sketch to the board. I have tried different baud rates (25000 & 15200), connecting with multiple USB cables through USB hub (which was no issue with the GT2560) and directly. When I hit upload the RX light on the board flashes every 4 seconds for a total of 5 times, then I get this error message:"avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout

Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your question.

That sounds as if you did not install a proper driver for the RUMBA board to go with MAC OS X 10.11 and in consequence, the board is non-responsive (and probably not really fully usable by the system.)

If you will tell me the RUMBA board's maker and model #, I will look for a driver for it for 10.11 that you may try installing. Let me know, please. Thanks.
