I'm designing a case for a dew-point ventilator controller to be 3d printed. The controller is implemented using arduino on an esp32. The project is based off of the code and HW implementation by Make Magazine Germany: https://github.com/MakeMagazinDE/Taupunktluefter. When starting out I was thinking this would be an easy project but it turned out that especially the lid with its lip and groove design and the parts fixations were not that easy. I'm excited to finally print it.

The file is parametric to some extent and the main footprint is based off of a master sketch. Many parts were imported as step files from grabcad. I used FreeCAD 1.0-rc1 which works like a charm for many things. Next thing I would like to do is to use the new assembly workbench. What do you think?

EDIT: I didn't mention the most important part. The device switches on a ventilator when the absolute moisture content outside is lower than inside a a certain room. This results in drying of the room that you ventilate like a basement with moisture issues. The dew-point acts as a proxy for measuring absolute moisture content.

Who can suggest an ethical SMTP provider for low volume transactional mail? I'm willing to pay up to 2€/month for a few hundred mails per month.

One of my tomato plants is doing excellent due to the warm weather recently (was planted 2 Weeks earlier).

Also some pics of beans in blossom. They don't seem to be that happy though, any ideas why?

And more tomatos:

The beans, salads, tomatoes and others are finally growing a bit quicker. With the fourth or fifth start of spring, I hope this time the temperatures keep staying up.

Tomatoes are still small but growing nicely.

The new raspberry bushes produce first red fruits.

Bonus: Happy chicken sharing some leftover melon.

After a cold and rainy start of spring, finally the beans are sprouting. We also have a bunch of tomatoes and brassicae.

Let's hope the abundant snails don't take too much.

Tomatoes, cucumbers, paprika, cannabis, brassicas, etc.

I just got an old Ender 3 for cheap and wanted to replace the crappy extruder with a nicer bowden extruder of my (now) direct drive Kobra Max. When I connect the new stepper, nothing moves. It's a longer stepper and a different manufacturer. Is the wiring different or VREF wrong or are there other reasons why it wouldn't move? The driver is good, since the old stepper is still working.

Thanks for any help!

Has anyone thought about printing narrower lines in order to get sharper corners? Once Linear advance or Pressure advance is activated, you don't get bulging corners anymore... but can we do better?

Has this been implemented anywhere yet? Does it have a name?

Hey, I've recently designed a Poster about the FHS since I often forget where I should place or find things. Do you have any feedback how to make it better?

Edit: updated with new version
