Day 7: Yes, Boards Can Be Fixed, But Extruders Can Clog

Dataman was able to surface mount solder the driver chip onto the driver board and we had a good test.  So, we have two good replacement boards in stock.  That's a relief.


But now we've started to have strange problems with the extruder.  Seems we can't get much to come out at all any more.  The boards suggest that bake at 220 and soak the tip in acetone.  So it's baking and soaking...

This picture shows good grooves in the filament, followed by a telltale dig mark where the motor burrowed in.  This indicates the motor pushed as hard as it could, but could not get past the hot end.
