Custom material profiles for Ultimaker 2/2+ problems

Recommended Posts

Well I have spent a few hours trying to follow the logic, perhaps others can help me out.

There's something not synching between the process listed on the https://ultimaker.com/en/resources/20982-custom-materials-ultimaker2-plus and using Cura 2.3

Let me tag @nallath so he can chime in from Cura

Here's what happened to me...

I wanted to have an Colorfabb nGen profile on my Ultimaker 2+. The process looks pretty easy. The one problem I noticed is in Notepad, it was a real mess to work with. I went and downloaded Notepad++. You can see from the screen shot that Notepad++ is way better to work with!

I created the profile using the settings I had seen work for others, from here, my forum and the Colorfabb site.

Basically: temp 230, bed 85, retraction length 4.5, retraction speed 45 mm/sec, fan 50, flow 100, etc.

I uploaded that in using the process in Method 2 and all was there.

Now for Cura....

I created a model and when I went to check on retraction settings, my only option was to Enable it, which i did. Curious, I went and hit the settings gear icon to see the settings...

The exclamation points won't let me change them, so I left well enough alone.

Well, come time to print, as soon as the print commences, the filament retracts a long way out of the print head completely. I paused the print and check the settings for Retraction and Retraction Speed. They are off the charts...way high. I correct them but realize I have to abort the print. I have to remove the Bowden tube, slowly move the material back down, trim off the strings and blobs, then re-insert the Bowden into the print head and load the filament in.

I try my print again and it happens again. I realize whatever I did previously did not save because the print was aborted.

The next time, while the printer is warming up the bed, I check and correct the values again!

My questions...

Why doesn't Cura adhere to the values of the MATERIAL.TXT file?

Do I need to create some profile in Cura to match the MATERIAL.TXT file to synch these up?

Please...tell me the proper process to save my sanity!

Yeah nothing to do with Cura on this one.  @nallath is off the hook!

It has something to do with firmware, since that uploaded data is being lost once the machine is powered off.  

If you have many SD cards, it can be a hassle remembering which one has the materials.txt file on it!

@tinkergnome - any insights? I haven't used the materials.txt feature. After you load them is there some save command somewhere you have to do to write to eeprom? Or could it be that some materials.txt files have something that won't write to the eeprom? Or they have too much information? (I know not that much memory is reserved for this).

@m42e and @LePaul please post the entire contents of your materials.txt file in case there is a character in there or length of string that is causing the problem (maybe materials have to be less than 10 characters long for example).

And note that when you upgrade your firmware - some firmware versions use different locations of the eeprom differently and sometimes your settings get clobbered until you resave or do a factory reset and then re-enter settings.

AFAIK it's just a firmware bug - and exists since Ultimaker added the retraction settings per material. But i may be wrong...

Here is a reported issue: https://github.com/Ultimaker/Ultimaker2Marlin/issues/113

...and:

 

@ghostkeeper added the "bug" label on 5 Sep

I assume, he has the hot potato at the moment... :D

(or at least - some insides?)

Hi @gr5 and the gang

As the others pointed out...I don't think it's me.  

Here's my file I have to import everytime I power up to use Colorfabb nGen  (I find these settings work great, reducing the 'hairy' prints significantly)

I can't figure out a way to attach the txt file asides cutting/pasting it in here

I only want to say I am suffering the same problems with MATERIAL.TXT as lepaul and m42e

I have posted my case in Very long retraction problem with ApolloX (Formfutura) and What are the various parameters in the MATERIAL.TXT file? threads, as I didn't discovered this topic before.

As far as I can see, there are two bugs:

1.- Importing MATERIAL.TXT is not working well, as retraction parameters loaded are not correct (always stores 255mm and 60mm/s).

2.- Importing MATERIAL.TXT is not permanent, as when the machine powers off the new profiles disappear.
