I would go for the mk3 if I vere buing one now.
It has some new features that makes it top the mk2s, and on top of that it's a lot quiter from what ive heard.

I get no result on ebay for 381180859843, but I'll do a search.

Not sure that I actually need it for this project, but it would be nice to have on hand.

do a search on eBay for "Servisol 6100009000 Plastic Seal 60 Protective Insulator 200ml"

3D printer, I've settled for the Creality 3D Ender-2 Mini.
I like the Prusa mk3's features and the CR-10 but I believe they are too big for me. For what I want to do, the Ender-2 is more than enough.

Now thats a nize looking printer.

It has many nice features. Heated bed, auto bed leveling and more.
Even with a smaller print volume i think it would be able to print atleast 95% of the prints I have ever printed on the mk2.

A large build volume is great when you need it, but you rarely need it to be honest.
Als. If you want to print with filaments that require hig + stable ambient temperature, it would be easy to make an enclosure.

Heres some of my other printed astronomy equipment. I printed my guide scope tube rings and dovetail clamps.
Ive got a lot better guiding this year than with my orion miniguider with aluminium fasteners last year.
Have not notices any flex at all.

I've pulled the trigger on the Ender-2 printer...

it's here, I have my 3D printer. It's amazing !!!

Cool.

Upload some pictures of the printer and meteostation when some prints done.

Here's a pic of the machine, I will attempt your weather station enclosure this week once I've mastered the settings for PETG carbon fibre filament.

Hello group,
MeteoStation I have built and tested for about a month. It works well. Good work.

Just a few little things.

1. Water penetrated the electronics. Problem solved with silicone sealant.

2. I do not start automatically at startup. I've already tried all the syntax. The readme is written :
What do you have in?

3. After switching off and on after a few minutes, the cloud chart rendering has changed. See the screenshot.

Do not you know why? I've already tried to stop the script and run it again, another restart, nothing works.

Thanks.

Tomas

I also get this on restart of the scripts, it does come back to normal after a few hours. Do not worry.

2. I do not start automatically at startup. I've already tried all the syntax. The readme is written :

I think that is for older ubuntu systems. You could make a meteostationWEB.service and enable it.

However I think the easyest way is to use cron.

Create a file in /etc/cron.d with the followin content

I usually make symlinks to apps in my home directory in /srv . That way I can swap versions by changing the symlink, and not worry about paths changing.
(If you get a error with no directory named /srv/meteostationWEB then swap places for dir and symlink. I often get those swapped on the first try)

Then change the cron file to
