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 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, bug I'll do a search.

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

So, I remember learning a long while ago a method of moisture proofing electronics.

It's as simple as spraying some wd40 on the circuit board(s). This will create a film that the moisture will not penetrate.

I would guess that this mightdistrupt the sensors, but could be smart for the arduino.

Have anyone tried this? WD40 is not conductive, so should work like a charm!?

You should watch most of the 3d printing videos in these YouTube channels.

They are a lot better in explanining thigs than I am, and covers both basic an pro tips.

Addiction alert!

I really dig the Prusa i3 mk2s. It's at the top of usability when it comes to setup and calibration. (now surpassed by the mk3), and have supreme quality!

There are ofcourse less pricy printers. I'v seen a lot of good reviews of the Creality C10 with a huge print volume.

I'll be watching some of those vids myself tonight. I'm at the Obsy, but forgot the charger for my laptop = no KStars, and the Obsy roof is frozen shut after sitting with 40cm of snow for 48 hours. My linear actuators capable of lifting 120kg does nothing, and I'm afraid of starting a fire if I ceep on trying!

Yay! 3d printers are awsome, so +1 forr that.

I'm using the Prusa i3 mk2s. One oof the best printers out there.
All the other i3 printers are Prusa clones :)

www.prusa3d.com/#our-printer

The improved Prusa i3 mk3 has just been released and features filament 'empty' detection and power loss resume. It also have a detachable flexibble print bed, so getting prints of the bed when finished is a breeze.

There is also a multicolor update for the mk2/s. Witch can be used for water soluble support material...

Nice script. Easy to get a full owerview of the sensors.

Could you check if you have the keyworsd MAX and MIN in meteostationWEB/meteo.rrd if you open it in a texteditor.
It's binary, so wont make mutch sense, but in mine I have both AVERAGE, MIN and MAX.

If anyone reading this thread have or will at some time print the housing, I've updated the drawings with some rain protecton.
I Installed a new DHT22 when upgrading, and so far it's working. Even after a week of snow, rain and fog.

Hi @procras and everyone else :)

I have been going trough the code for the MinMax error, and to me it looks like the tool is not able to read meteostationWEB/meteo.rrd and write average values to meteostationWEB/html/CHART/AVERAGEvalues.json. I can hovewer not find that this file is being read by any of the other scripts.

So the meteoRRD_MaxMinAvg.py script might try to get (fetch) the average values from the rrdtool with

 ret = rrdtool.fetch('meteo.rrd',consolidation,"--start",str(start),"--end",str(end),"--resolution",  str(res));
where the consolidation is AVERAGE, MAX, or MIN. I'm starting to think that the rrdtool does not have AVERAGE data before a set amount of iterations.

If that is the case, then a clean install with the MinMax error should only have the html/CHART/MAXvalues.json and MIN.valuses.json + no AVERAGEvalues.json

It should however not have anything to do with the soundingstation or the meteoconfig.py settings.

Yes. Wind speed would be great, as it can be dangerous for our flip top observatories with high wins!!

I've seen that to.

Looks like the flags are sometimes set wrong after a reboot. Not easy to test as my station is remote, and I cannot flash firmware remote.

In the meteosationWEB/mereoRRD_updater.py line 67-70 you have

statusVector=indi.get_vector(INDIDEVICE,"STATUS")
cloudFlag=int(statusVector.get_element("clouds").is_ok())
dewFlag=int(statusVector.get_element("dew").is_ok())
frezzingFlag=int(statusVector.get_element("frezzing").is_ok())
So it just checks the flags from the firmware.
Not sure if it's indi_duino or the firmware that sometimes gets this wrong.

I think I found the issue I'm having.

I did not have correct settings for timeout in sshd_config

I added this

TCPKeepAlive no 
ClientAliveInterval 0
ClientAliveCountMax 1

I tells the sshd daemon to send 0 Alive packages, and not to disconnect before atleast 1 Alive package is not returned.
Should keep the tunnel alive until I close it or reboot.

Fingers crossed :)

I see. You just start indiserver on different port, so you still can start the other drivers on default port?

I am testing with making a script thar runs @reboot via cron. This first starts indiserver with indififo. Then starts meteo, dome, wounderground and duscap. Then it opens a reverse tunnel to my webserver and executes. /startMETEO. sh

I have some scripts that i use to start indiserver with chaning. The server with meteostation is the last in chain, so as long as indiserver is started, those scripts works well.

I have been testing the last day or two. Mine flatlines even if I only connect to meteostation, so I'll have to do some digging

I'm also having som flatlining issues.

I just do not know if it's because of ssh tunnel timeout, or if indi_duino is crashing.
Not sure why it should, as all the values from the sensors are ok. No timeout or anything.

The MinMax error i somtimes have, but other times it's gone....

I reverted to commit 781e4a2b01883ddc09710eaebdb94c704b3febe0 and the usual behavior is restored. (Except the strange Alt using raw Dec values for parking)

As to timeout on connect + wakeup, I do get those sometimes, but clicking connect once again works. Not a big issue for me now, but it would require connecting the driver manually before starting automation.
