Introduction
The adventures continue (still no end in sight).
Part replacement
The wobbly upper plate was too small to adjust the holes, so we manufactured a new one. Take a wooden plate, cut it down to size, use precision measurements and a power drill. Drilling is fine after a beer, but do the measurements before.
Looks ugly as hell, but does it work?
Yes. Yes it does. At least in comparison with the previous model.
On this new, high resolution version, we noticed the next problem: drooping around any edges and curves that go outward. Note that the deck and upper parts of the boat look fine. According to our research, this is an overheating problem.
Low temperature printing
Our first attempt was to lower the temperature of the bed and print head. Turns out, the bed wasn't hot enough for the plastic to stick to it, and we got the following result:
Next, I tried some external cooling by pointing this heater (!) towards the printer. I don't have a desk fan, but this heater can function as one (blowing cool air only), so I let it rip.
Better, but not perfect.
We decided on getting some 3rd party fans designed specifically for this stuff. The project was on hold, again.
