UM3 - How do I change the default material settings on the machine itself?

Recommended Posts

Hi, I'm trying to use some non-UM filament and can't seem to change the default materials when Loading/Unloading on the printer itself.

For example, the PVA settings are fixed so if my material has a slightly higher temperature then it will be harder for it to extrude.

Cura also thinks that the material is the default PVA when it's not!

Thanks!

AFAIK that is not possible, just load the material into the UM3 with a similar material profile. In Cura you can create other materials and hopefully a custom print profile (bearly as it is bugged), up to now you are required to fill out every option yourself each time you slice a model. The print will use this material then when printing. Since 2.6.2 I get a message just before printing that I'm not printing in e.g. nylon, but you can skip that as I have the sliced model setup to print POM. I have not tried 2.7 yet, so I don't know if the material and print profile bugs are fixed. I haven't had the time to look it up in the code myself.

Great thanks, yeah I've noticed a lot of bugs and I've only had it a few days...not something I expected from a printer that has been out nearly a year and has such a good reputation!

Also, could you link to POM material and your settings please, VERY interested to try that out! It's similar to Delrin right? Does it work with the Ultimaker PVA?

Thanks!

Somehow I posted a reply, but that does not show...

So here we go again... A little shorter now, sorry for that.

Delrin is POM. I use Nylon for loading. I adapted the profile to a lower temperature, lower speed and lower or no fan speed.

I have not tried it with PVA, I don't know if it is similar to nylon which does work with PVA.

Hiya,

as my printer is printing I can't check but on my UM2+ I know I can create custom material profiles.

however I have found that the CURA material profiles do override the printer material profile. I get a warning when I send the file over wifi. so I believe that via USB it will do the same.

The OP asks for material profiles in the firmware, not Cura profiles.

And yes, it asks for override of the material if you sliced with a material different than currently loaded in the machine. But you are not able to load materials that are not Ultimaker branded ones. In that case you need to select material close to the one you are loading. E.g. choose nylon when you load POM, choose CPE when you load NGEN, choose ABS or CPE when you load PETG, etc.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
