Xmax stuck triggered, even when uplugged
April 27, 2021 09:56AM
I have a TAZ6, which uses the Rambo board, and the Xmax is stuck triggered, even if I unplug the connector from the board, so seems it's something with the board. I'm thinking maybe if I can find and follow the xmax circuit traces to some component I can simply remove a capacitor or some other component, to permanently open the xmax circuit.

Any thoughts or advice on this or any other method to get my printer back up and running? I hate to just replace the board in case it isn't the real problem or if whatever fault will just break the new one also.

Is it possible that the software has been changed? If the pull-up for the Xmax is enabled and it is set to be triggered when high then it would always show as triggered - even with the limit switch is unplugged.
