Change Confirgureation: What does this even mean?

[t-squareddesign 2]

Hi everyone.

 

So every time I attempt to start a print job, I keep getting the message that reads:

 

Change configuration Material 2: PLA (generic

PrintCore 2: AA 0.4

 

This makes no sense because the material in printcore 2 is PVA with the recommended BB 0.4 extruder. I even changed the materials in the material selection screen. But it keeps saying this. WHY?

 

If I neglect to change or fix this issue, is this going to affect my prints?

Also, at this very moment, I'm running a 3D print with this PVA support material. It seems to be crackling a bit as the print gets applied.

 

Is the extruder too hot for the PLA because I ignored the "change configuration?"

Change configuration means that CURA and the printer have two conflicting information as to what kind of filament you have put in there.

 

In your example, I think you need to check your settings in CURA: make sure that Extruder 2 is set to Materials: PVA and Printcore: BB 0.4.

 

It can affect your prints since settings for various materials varies, so it's always best to make sure that both CURA and the printer are set on the same material.

 

PVA can crack because the print temperature is too hot, but also if it has taken some moisture from the air. PVA is extremely sensitive to humidity and will absorb the moisture in the air if let out in the open, or even in the bag but without a dessicant or a way to absorb moisture, which will alter the quality of the material.

Thank you so much for your reply.

 

I do think my PVA may be moisture damaged by the humidity. I put some dry heaters next to the spool to dehumidify. However I'm still having a problem matching the configuration of my Cura to my Printer

 

I'm not sure how to adjust the settings correctly in either the Cura or the printer. I tried everything. I've provided screenshots

BB core can only accept PVA material in both Cura and the printer. So, you are covered there.

 

As @Brulti stated, you have to make sure that your settings in Cura are correct. In my case, my filament is in a polybox, drybox and cannot read the chip. Even if I have UM materials loaded it will still require me to select generic PLA or whatever. It will always have to be generic. The machine is just warning you that the material does not match in case you selected PC and you have PLA loaded. That would not be a good combo. But as long as you sliced for PLA and have actual PLA of any brand loaded, you will be ok. This goes for any material you can choose.

 

In matching the proper materials to their type, it is the slicer that is controlling all printing temps. This gives you the subtle controls over material brands and even differences in batches and colors. The only automatic thing you cannot override is the loading/printcore temps and the move material/printcore temps.

 

The only time you may have an issue is if you are using one profile to modify for a setting that is not directly supported such as PETG. Some use a CPE profile, some use a Nylon profile. You must remember what material you are modifying so that you can select the proper base material on the printer. The most important thing is to get the loading temps correct so that you do not try to push a high melting temp material (Say PC) at PLA temps. Just will not work and that is what can damage your system, trying to force unmelted plastic through the cores. Or, if you have PLA as a slice setting in Cura, but choose PC as the loaded material on the printer, it could burn the crap out of the plastic and clog you up or just ooze all over the place and leave a nasty mess.

@t-squareddesign For your PVA problems, and I'd say, for most filaments anyway, you can use this wonderful idea by @ultiarjan: the drybox: https://www.thingiverse.com/thing:1837907

It works for all filaments, and I was even able to save a spool of PVA that I thought had gone bad due to humidity. I would also advise you to store all of your opened spools of filaments in big sealed boxes with dessicant or humidity absorbers, to protect them for the ambient moisture. Other materials, like PLA, can also go bad if left in the open and unused for some time.

 

Someone from the Utimaker Team told me, in another thread, that the spools of filament should be kept under 55% humidity to ensure that they retain their quality. My boxes, be it the small ones next to my printer or the big ones used for storage, are between 20% and 30% of humidity, and I had no problem since then, even with the PVA.

Interesting, I thought that what was inputted in the printer was mostly for information, and that, in the end, it was CURA that controlled everything, from temperature to speed to extrusion rate and all. So, if I choose PC in the printer, and PLA in CURA, despite the fact that CURA will send info about PLA, the printer will use the temperature setting for PC?

I just noticed something today: changing the material on the printer does nothing.

 

I'm using the dryboxes as well, so, no NFC recognition for UM materials. I started a print with TPU today, so, my printer is set on TPU 95 (Generic) and CURA is set on TPU 95 (White). When I hit the print button, I get the configuration alert, and the screen of the printer shows a message 'change configuration to TPU 95 (White)' whihc, according to the web-based print interface, should make my print start automatically.

 

Except that it doesn't. Clicking 'confirm' on the printer does not change the configuration of the printer nor what is displayed on the web-based interface, and the print does not start, forcing me to click on the 'ignore configuration' button to have it start.

 

This looks like a bug, or maybe a feature that isn't completely implemented, I don't know...

One important thing to remember is to mention the machine you're discussing.  The behaviour is different between Ultimaker3 and ultimaker2. While for the UM3 cura settings are leading, for the Ultimaker2 by default the printer is leading (using UltiGcode), but you do have the option to slice using RepRap gcode, which will override the machine settings.

 

I personally would like Ultimaker to choose a common approach for all machines and change the workflow for the Ultimaker2 to be the same as for the Ultimaker3, while this would be a big benefit for people using both machines, this would obviously also mean a workflow change for Ultimaker2 users.

I have an UM3E, like the original poster on this thread.

 

That's a good remark though, and I thought that it was already the case. It would indeed be better if all UM printers would be have the same way.

YUP... Me too... just got my UM3E... love it... but hate the start up... spent over 2 hours today, trying to change the UM3E's settings on that stupid dial around selector.  CHANGE THAT!  When I pick select material manually, it goes into an error message saying multiple materials identified, pick one.. so I try and it bounces back to the error message not letting me scroll down the material list.  So I abort the print and it rebounds and tries again asking the same point as Brulti said, which is asking me to "ignore configuration."  IF MY CURA is driving the slicing and hence the head temperatures then I am good to go, but then the loop happens again... insanity of doing the round and round over and over... then, as if the machine decides it has sufficiently aggravated me, it magically starts to print.  I've run 5 or 6 small 1 to 2 hour built part sets and then a 39 hour build part all with the same headache of a start up.  But once they go, they go nice.  Frankly, I don't have the time any more to babysit the start up... IS THERE A BUG IN THIS SOFTWARE ON THE UM3E????? (My cura is working fine). 

[Brulti 177]

Strange. Usually, if you ignore the printer and just go through CURA and the web interface, it should work.

 

I mean, you start a print via CURA, you get the error message, click on it, browser opens, click on the 'configuration' button, then just click on 'ignore configuration' and it should start printing without a hitch.
