I have been struggling with serious under-extrusion on my Ender 3 for a while now. I tried changing out the extruder, swapping hotends, new PTFE tubing, cleaning the hotend, new nozzle, and changing...

Life got in the way of this project and I have not been able to post here for a while. However I did manage to get some more work done on it. In particular I finished up my experiments using...
It has gotten up to 109 F here, very hot indeed! However my test house is holding up well. There are no signs of warping and there is only a slight discoloration on the plastic.
I did notice...
I got my sensors all wired up. Well all but one, I managed to pop one of the digital temp sensors. I will need to order another one. Anyway I ran a test overnight with the sensors in a closed...
I got some black PLA, it blocks the light 100% even with only 2 perimeters. I also tried painting my green PLA black and even with one coat of paint I was able to block out 100% of the light. So...
I also finished printing my test containers. The above test brings there value into question, but I will test them out as is and after painting them just to see if we can detect a benefit. The test...
I wanted to test out how well different wall geometries block out light, so I printed a 100x100 mm square that was built up out of 4 different thicknesses. Then I painted the flat side with two...
I redesigned my sample prints to be both skinnier and taller, I think that more closely resembles the real thing. I then made them with a 1.6mm, 2.4mm, 4mm and 8mm thick outer wall, and 2-3 0.4mm...
I went ahead and published my code, it is still a bit rough and lacks proper documentation, but it should work. This is built around an arduino uno and a Adafruit data logger shield. Add on top of...
I finished up my arduino code and calibrated my analog temperature sensors. I still need to finish wiring up the other digital temp sensors and see how well they compare to each other.
At the...
Our agave plants are starting to bloom. They rely heavily on bats to help them go to seed.

The rest of the hardware came in,...
My thermisters came in, I picked up 8 thermisters with 3 meter cables that are housed in metal pipes and epoxied into place. That should be safe enough to leave in the house even with bats (if I...
While waiting on the new temperature sensors I thought I would do a little bit of a design sanity check. I modeled the house in one piece as 3-4 cylinders at the final height with no internal...
I have been looking into various ideas on how to control temperatures in the house. Here are some potential ideas to explore
- Print a shade on the outside that keeps direct sunlight off the...
I managed to clean up the images above, the way I was hosting them before I could see everything but no one else could. Hopefully that clears up some confusion.
I ran two temp tests overnight. ...
Thank you for taking the time to look over my project. You raise good questions, hopefully I can try to answer some of them to the best of my ability.
First the house you are showing is...
Question for later, does the pole absorb heat from the bat house via conduction. Figure out how to mount a temperature probe to the pole to see if it is cooling below ambient. This would only...

Here is the same data as above but as a delta relative to the ambient temperature. It is interesting to look at it this way. You can see that the bat house offers very little...

First Data! I need to clean up my logging code a bit, and work out a better way to visualize the temperature differentials, but we have data!
Looking it over it seems that the outer...
Ideas
Take temerature readings in the house to validate its thermal characteristics. I plan on comparing that to temperatures inside an inverted 5 gallon bucket and in an insulated thermos as a...
This is a 3D bat house I have been working on. I did not want to post the plans until I have had time to validate the design with real bats. However I need a place to talk about the design, so I'm...
I have reverse engineered the sender software that XYZ uses for there newer jr and mini printers. You can read up on it here (http://www.soliforum.com/topic/17028/print-gcode-files-to-minimaker/)
I have both an creality ender 3 and an xyz miniMaker. Both are nice printers and both can be had for around $200. The ender 3 is open and can run any firmware and software you want, while the...
After I do the paper test I run a few quick test prints and adjust the z offset up or down as needed to get the first layer to stick well. If you have installed your own version of marlin consider...
If the filament is curling around your nozzle then it is a sign that your z-height is too high.
