Printrbot Play Printrboard LED Flashing

Postby Bigdfromaz » 2017-Dec-Fri-17-Dec

For the last couple of weeks I have been having issues with my play. First, it wouldn't connect via USB. I disconnected the upper fan from the printrboard icsp and was able to connect. So I flashed the firmware and was able to get everything running again, but without the upper fan and by disconnecting the PSU (I upgraded to the extended Y axis and heated bed) and using the original PSU. Everything seemed to be working and I was getting some good prints once I recalibrated everything. Today I was starting a print when the machine just stopped. The LED on the printrboard is flashing when I plug it in and resetting the board isn't helping. Also, it isn't recognized in Cura and won't connect anymore. Any advice?

What version of Printrboard do you have?
On Printrboard versions A through F, the LED is not under program control, but simply indicates the presence of power. In that case, if it's flashing on and off, it would indicate an intermittent source of power. However, I have no knowledge of how the LED on a Rev G board is connected or controlled.

Thanks, it's a RevF5. I'm going to reconnect the other PSU and see if that helps.

That was it. I think although I wasn't using the heated bed, it was still drawing power. New fan gets here soon, so hopefully I'll be back to printing reliably again.
