True, I’ve seen many molten rolls of filament because of overly warm ovens. Make sure it doesn’t go over 60C and you’re good. Mine is good, has a little overshoot when heating up, but if you let it warm up first and then put the filament, it generally stays very close to 60C. I havent had problems. Other ovens - be careful. Food dehydrator is better, but if you don’t have it, you may as well buy an actual filament dryer. Desicant beads didn’t work for me. They do the trick of maintaining the dryness, but if you have ANY built up moisture in your filament, the beads won’t do much.

As others have mentioned:

• Dry your filament. Stick it in the oven for 2+ hours on minimal settings. If you have a fan in the oven, even better. edit: use the printer bed, see comments below
• Tune your printer. Do a temperature tower with your dried filament. Lower temperatures might improve quality at the expense of lower layer adhesion. Do a flow calibration routine. Overextrusion can also have effects like this.
• Slow down the printing. Increase minimal layer time, which might have an effect. If it’s original E3, it has relatively poor part cooling, which can be compensated by slowing things down.

Nothing wrong with Ender 3, if you thinker enough, you can get results as good as any other printer. But it may require tinkering. The model that you’re printing is difficult with FDM printers of any kind. It has thin, delicate parts with steep overhangs. It can look better, but it’s gonna be hard to achieve. Resin printers are definitely a better choice for this, but you use what you have.

You could use just a regular 5 min epoxy. I frequently use CA glue, but depending on your use case, it might be too brittle.

Any PC that has virtualization features can be used. Unless it’s very old, I’d say it’s supported. But it may not be enabled in the bios by default. It’s called VT-x for Intel and AMD-v for AMD, I think. But both are supported for at least 10 years on almost any PC.

It’s a hypervisor level virtual machine host and you can use it to install multiple os’s on the same machine with little overhead. I’ve been running haos like that for a few months now and I’m super satisfied.

There is indeed multiple ways of doing anything in freecad. But over time, I prefer staying in Part design as much as possible as this makes it more modifiable and customizable and there are plenty of reasons more for me. But in the end - whatever works is good enough.

Shape binder is what you need. Shape binder can be used to reference geometry from another body. What I would do is I’d make one pocket on the main body. Then select another body and make it an active body. Then select the pocket you made (the surface or the edge) and create a shape binder (part design). This will effectively import the selected feature from the first body and you can reference it from second body. Make sure you hide the first body, as it somehow gets in the way of shape binder, for some reason. Repeat for third body.

Looks like you’re just missing Linux to compete the list. It’s not for everyone yet, though.

I’ve been following him for years and this video had me very disappointed in him. Very arrogant and condescending of him. I know he did similar videos on solar roadways, but 1. he is knowledgeable on that subject, and 2. the people behind that were clearly scammers wanting funding. Here, this is just an unpunished paper with nothing to gain if it turns out it doesn’t work, yet he still treated them as garbage. God, I wish this turns out genuine if only to make HIM look like a dumbass (not to mention this would be huge).

I have a newer ZigBee 3.0 dongle and run a few add-ons, but nothing big - z2m, nodered, mosquito is all I use. I will upgrade anyway, but I’m not in a hurry, it works fine, apart from an occasional delay in switching, which might be network related.

When you switched from pi3 to NUC , did you notice any performance improvements? I’m asking because I run my setup on a rpi3 and it mostly works ok, but the latency is sometimes high, so I’m wondering if upgrading the host will improve things.
