Our MakerBot Replicator Dual needed some help. One of the extruders was clogged. It was the type of clog that could only be fixed by partial disassembly. It seems to be pretty happy now but the filament loading sequence seemed to produce an extrusion that periodically sounded like it was slipping. This test print seems to have worked out fine, so we’ll just keep an eye on it.
A BlueSmirf is a bluetooth modem that can be integrated in to Arduino based systems. I’ve added some pins that I’ve bent to allow the card to be positioned vertically from a breadboard for easy test and hopefully better range. The bent pins will likely work well if we plan to integrate it in to a headband or other wearable project later on.
