The Two New Parts |
The LCD and the Knobs which are on one of the I/O Expanders will require some new wiring on a new Propeller USB Protoboard that I plan to use. Software is about the only way to do real tests here.
The one part that I can not get to work is the I2C POT, which will control the Backlight and sound volumn, the POTs are not necessary to do the initial checkout. And, maybe I just have not found the magic that makes it work.
More testing needed.

Parts being Cut |
When working correctly, the PlamaCAM creates a lot of dark smoke, which tends to collect on everything (nasty stuff). I was wondering what the smoke actually is? The only ingredients in the process are "Electrons, Air and Steel". Although, at 10K degrees, almost anything could be being created.
Lots of Sparks and Smoke (more smoke, less sparks, makes for cleaner/better cuts) |
Later, I discovered they are very thin hollow spheres! Smashing a single sphere releases something that effect others in close proximity. Maybe they contain compressed gas, or maybe they release an electric charge, or collapsing magnetic field.
More investigation needed.

I think that is Iron oxide - the same what the ferrite rods/toroids are made of
