So, drying filament with a nice automatic machine seems a better idea than struggling the hard way with ovens and such. Enter the [name supressed] from [brand supressed], a fine-looking device. Within a few days the helpful device decided to leave the heating element on all the time, even when powered off at the control panel. I suspect a FET…
So after testing the IR device in Serpent Lanes I found some instability due to temperature change. I decided to use a new sensing technique, and this gave me a chance to try a different design for the upper lanes. The columns are taller, more stylised, and feature colour-changing capitals (tops). Construction is a bit sturdier, and replacement far easier.
Better is the Enemy of Done Words to live by. I've always hated napkin designs and quick sketches. They are ugly and confusing. There is no denying though, that they get the job done quick. The ugly schematic lead to a bit of ugly construction... So we have 240V switched with a circuit breaker, coil power switch, amp and volt…
My view is that you have not designed a thing until it has been tested, and it works.
