I've been tinkering with 3d printing for about a year now and never had any experience before.

Tried most softwares out there that are free and seem to allways comeback to fusion 360.

For slicing I like slic3r PE in the free tier, even tho its interface looks dated it has some very nice features and handles material/printing profiles really great.

But if u want an all in one package it's simplify 3d. Even tho you don't get the same control as slic3r and it doesn't handle material profiles as good.

It has a clean interface, great gcode preview and a few killer features like custom supports (yes there are other slickers with this aswell) and multi processing that lets you switch profiles anywhere in the print or model.

Yes it's a big price now days for a piece of software. But if you are going to use it alot it is well worth it's price.

I must have been drunk when I ordered this. Any idea what I have ordered? I ordered thru dirtypcbs somehow.

Does look a little bit like this PCB but not really. Have I found a early version and drunk ordered 10 of em?

Extension cord it is!

Just started my project of monitoring the water level in our water tank. I have bought that waterproof sensor from the hardware guide but it only reports around 2 meters in testing.

Problem is that i have about 8 meters down to the water level so i either need to lengthen the cable to the sensor by about 6-7 meters down the hole or find another sensor to do the job.

Any idea? this will not be battery powered so no issues there.

@tekka
How about I'f i replace my serial with a Ethernet gw?

Do not want my pc running all the time. Just to debug

Ok this might be a realy stupid question but im what you call a "nuub" ;)

If i want to monitor my current setup (serial gateway on a pi3) on windows/mint. Do i build another gateway and plug it in the pc?

Sorry if i missed the instructions on this

@sundberg84

Yeah trial and error I guess. I have an outlet outside that I could put a repeater in so i might start with that one.

And caps are on all my nodes so far ;)

Thank you :)
Where can you find these changes?

Heres the deal
I dont live in a giant house but the walls of the house are pretty thick (inside around 30cm and the outside walls are around 45-50cm) the outside are mostly made of wood, have one wall around my heatersystem that is concrete.

I spent days debugging a masterpiece of a mailbox / light sensor that was battery powered and when it finaly was soldered and working as i wanted i happely strolled down to the mailbox (around 50 meters from the house) to install the thing..

Aaaand lost contact, rebooted, walked 10 meters up, rebooted, 10 meters up and so on until i basicly where at the otherside of the wall to my gateway.

So i searched for the solution and found repeaters!
So far i have built 2 of them and placed em togheter with nonsleeping PIRs. And i think they are working, no idea how to tell if they actualy are repeating anything.

The plan is too build a few more in the house and atleast 1 outside where i have power, just to be safe that the range is optimal around the house and a bit outside of the house.
But i read a post in here about repeater looping problems and such so is it a bad idea to install extras even tho it might not be needed?

I need to check my node. It Constantly shows 80-90%. Have switched forks and plant same number. If I pull it out of the dirt it gets to 0%

Using only the fork no board in the middle with the alternate current sketch.

I rebooted domoticz and it got the right values for the childs :)

Any tips of geting rid of unwanted values from the child's here?

Have been debugging and experimenting with a lot of different sketches and I finally got it to work. But old values are still in there.

not sure of link worksge. on phone atm. will paste it from comp later if its not working.

@mfalkvidd

Hmm i have a combined sketch of the pir and dht example that works fine on a node that Can Sleep for a bit and interrupt with change on the pir.

But if i take that sketch and change the Sleep with interrupt to a wait(sleep_time) the pir is not registrering movement between wait Times'.

FIf i remove the wait alltoghter the pir is reporting the status every ms instead with the result that the dht can't read the temp!

About to built a dht / pir / repeater.
Since i cant Sleep it do i need to change all sleep with wait?

In the dht example there is a Sleep to let the sensor settle before Reading. Should this be a wait instead then?

This is what i did, the box should be the mailbox right now but aprently i need to build a few relay nodes aswell.

@rnollen

I am about to set a lux sensor outside any day now (as soon as the debugging is complete that is).
And i am going to place the board inside a glassjar, drill a hole in the top and seal the cables using a gluegun or similar.

Should be waterproof then right?
