It’s been a couple of weeks since the top of the filament storage box was completed. In the time since, I’ve been working on the bottom. The first thing that had to be done was to add a drain for the water from the dehumidifier. I did this by adding an aluminum hardpoint glued to …
With the sides of the box completed, it was time to glass the top. The layup itself was pretty straightforward, since it’s just a flat piece of glass that laps onto the sides and back. I added aluminum hardpoints for the screws that will hold the electronics enclosure and another hardpoint that can be used …
Since the last filament storage post, the storage tube assembly was microed into place. I covered the foam around the hole with duct tape to prevent getting micro on the foam surface, and poured slurry into the holes. The idea was to get enough slurry into the holes that it just filled all the empty …
The work on the filament storage box has lately focused on what to do with the filament tubes when they’re not used. The box will fit up to 8 1kg rolls of filament (or 4 3.5kg rolls), and those filaments will exit the box in PTFE tubing through the bottom of the box so they …
After 4 sides of the box were assembled, it was just the top left. This should have been quick but was delayed by the need to first bond the bracket that will hold the circulation fan to the inside surface. Had I designed the box today, with the intent to use the bed heater, I …
After starting to assemble the filament storage box, I was distracted by the house fumigation and repairing the Flightradar24 antenna, but this weekend I finally had time to apply the corner tapes to the inside corners. This is pretty simple, the idea is to apply a strip of fiberglass cloth to join the two sides …
Progress on the filament dryer was stalled over the summer since all free time went into the repainting of the room. The next thing to do on the box itself was to figure out a way to mount the internal circulation fan, figure out how to run the wires, and assemble the panels into a …
After designing the circuit board, I thought I would get back to glassing but nothing got done on that end before all the components and the circuit boards arrived. I’ve soldered surface-mount boards before using the “smear flux everywhere and touch the pins with the solder iron” method, which works but is pretty slow and …
Lately, the glass work on the physical box has been on pause since I realized I needed to work out what the connections to all the sensors is going to look like. To work out the electronics, I buckled down and started designing the circuit board. I had a vague notion of what it needed …
After glassing the cover for the dehumidification channel, I needed to mount the thermoelectric cooler. Small tasks are best now…. The hole fit pretty well, there’s a bit of clearance but I’ll seal this up with some silicone when mounting the cooler for real. On the outside, I had to drill and tap the holes …
