I pretty much only print with material from them.
The PLA I use is for visualisation models only but have made a bunch of prints from their PETG that is used in industrial environment mainly for material handling and is holding up great so far.
I dont think they have started selling recycled PLA yet, the ABS popped up on their site this summer.
All PLA is bio degradable at some extent as most of it is based on corn. Dont know if they have released PLA based on cellulose from our forrest industry yet, but thy are working on it.

Add North has a program were you can return empty spools and scrapped material.
They even pay the shipping cost.
You get a discount based on how much you return.
They only accept PLA and their own brand as return but it's a good thing.

Ive done a fair bit of long think nylon pieces with a lot of warping issues initially.
I learned two things that really helped.
Dry the roll before use, 60 degrees on the build plate and leave the roll in the chamber (enclosed) for a few hours.
I used way too much glue stick initially, just a very thin layer or print will detach.

sqrt3 is a bit of a strange name: Whereas sqrt is short for square root, sqrt3 is actually the cube root.
Square root of a value is the inverse function of square of a value: sqrt(value * value) = value.
Cube root of a value is the inverse function of the cube of a value: sqrt3(value * value * value) = value.
Here's a calculator: https://www.calculatorsoup.com/calculators/algebra/cuberoots.php
I didnt know the phrase in english so thanks for the lesson.
(Even though math are considered to be the common language of the universe 😄)
Cube root what was I was looking for, hence writing it in our native language too...

Roughly scale with 0,745 , or more exact, sqrt3 (0,6/1,45)
"Tredje roten ur..." in our language 😉

It seems that the feeder tries to 'jam' the material into the print core what results in a thickened wire (which makes it harder to pull it out of the core or to change material.
Does anyone experienced similar problems and/or know a solution to this problem?
I suffered exactly from this (UM3), the front fan was dead.
Didnt notice at first since side cooling fans and the one to my HEPA filter was running.

Make sure Cura shows all settings then you'll find them.
Or use the search function
-
Your upper flange looks wider than the lower, hence the need of a supporting wall there.

Hi and welcome
I think you also need to adjust support X/Y value due to the slope.
My first example Z is set to zero and X/Y default Cura calculated value
Adjusting X/Y value will close the gap.
(I wouldnt go to zero gap though, usually difficult to remove support then)

@ctbeke Dont know if this is useful for you but had the machine turned off a longer period last week (thunderstorms and several power outages). When I restarted it I could see it had renewed the IP adress and now I can connrct to the job queue again.

Thanks.
As long as it works through SD card I'll wait patiently 😉

Used geometric sequence to calculate but arithmetic might have been better.

Today I printed 600 grams of PETG scrap...
Miscalculated how much was on the roll and found the printer printing 5 mm in the air this morning.
Made a label to show approximate length remaining so I hope this was the last time. ( Rounded the values so it might look some irregular)

Suddenly I cant access the print queue, neither from the monitor in Cura nor through browser.
I can access the default page through the browser and read temperatures so I know I'm connected.
Printer is connected through LAN cable.
I believe I have the latest firmware
Have tested both Cura 4.0 and 4.2.1, same results
Trying to access print jobs through browser ends with error message "502 Bad Gateway"
Cura says there is nothing in queue but I have sliced and sent job over network.
I have done a Cura connect reset from the printer
Also hard reboot by shutting off power but nothing seems to work
Only option now to print is through USB flash drive.
Any ideas what to test?

Is it a flat surface?
Ironing has little, or no, visible effect on a curve surface.
Depending on your model, you might get better result by de-selecting "Iron only highest layer"
I use standard cura settings for ironing with PLA

Welcome to the forum
I cannot save in x3d in my Creo version but as in most tessellated formats in Creo you probably can, and must, set the chord height.
Set it as low as your model accuracy allows and try again.
Also check if you have any options to set export units.
Otherwise, try the good old stl format but dont forget to set chord height.
-
Great that it was that easy (took a while for me to figure out to be honest)👍
Top surface, make sure your top thickness is about 6x layer height else it might sink between infill pattern.
Ironing is a great feature to use on flat surfaces to enhance appearance. Enable that under Shell settings.
For most materials default values are good but I normally reduce the flow to 5% when running PET to avoid lumps.

Hi
The shapes of those holes looks just like mine did a month ago.
All screws to the motor had gone loose so just tightened them and it was all good again.

Done a few as you describe it but never had any issues.
Just one thing I remembered from another field, make sure you have no interference between the different parts.
That can create a mess in many different applications.

If you dont want to cast, try TPE (my choice would be silicone though).
Less grippy than silicone and less wear resistant than PU but a good alternative.
PP is almost like PET so not grippy at all.
TIp for @geert_2 : If you want to cut or machine PU, put it in the freezer or use CO2. Makes life a lot easier 😎
-
You mean °C and not °F, right?
Cant see your images but you need to show your results to get better answer.
Often when you see pictures of great quality models they are the result of hours of post-processing, like sanding and acetone smoothing.

For general stress analysis all the major cad systems has their built in FEA modules that usually is rather easy to handle for non analysis experts.
For stand alone system (yet with cad integrations) my "go to" package is Ansys. Harder to learn and use but has all the bells and whistles you can ask for.

Might be on to something.
First failed prints was Cura 4
Now printing with Cura 3,6 and I'm past the problem area.
Can empty spools be recycled?

Well, I dont think the polar bears would agree theres not enough CO2 around...
Trees are a re-newable resource, oil isnt so burning plastics doesnt add value to the equation in my mindset.
In my case the empty spools goes back in the same big cardbox they came in, about 10 each batch, and the delivery truck will not travel much longer than the one to the waste management station.
