I've started getting this SerialException error when using OctoPrint
every time after starting a 3D print. This problem would only manifest itself when printing, I could use the toggle buttons to move the extruder around on all the X, Y and Z axes, could manually extrude, etc. At first this really baffled me, but then I realised what the problem was.
This is the snippet of the console output in OctoPrint that was coming up for me.
The problem turned out to be with the power that my Portabee
was receiving from the power brick. I've recently did some rewiring by adding some click-in connectors so it's really easy to disconnect the printer and remove it from inside its box. One of these connectors, notably, the power connector wasn't making good contact. There was a piggy backed connected coming off of this that was feeding just enough power to the printer to do some operations manually, but when the the device was in print mode and using constant power, the Gen6 board would simply reset as it wasn't getting enough juice.
I fixed this by using a heavier gauge wire to connect the click-in connectors, now there are no more resets and its printing just fine!
