See also i.e notes on 1.5 update which says "Change material while print is paused. It is now possible to pause the print and change the material spool in the paused state."

Hi there, apologies for pulling this post from its gave but "Change material while print is paused. It is now possible to pause the print and change the material spool in the paused state." is from 1.5 release notes from June 2022. What has then be introduced and how can it be used?

Yes... but to play devil's advocate (again, I do want this and more on the UM2+C) Cura and the printer are two different things. Cura is the slicing software. It can be used with the UM2+C or any other printer. Thus there are functionalities that are present that aren't supported by all printers, even the ones sold by Ultimaker who does both software and hardware. So it's a business decision from Ultimaker. They decided that for the market segment, it was fine using a simpler hardware controller with a simpler firmware despite the loss of functionality. Disappointing to me, and to you, but that can still be considered out of specifications. Anyway it clearly isn't their focus for now, even though, yes indeed it could be done.

@Nico04 you can look at my post history but a word of advice here, don't swim against the current. I asked numerous time and people have basically told me, I'm wrong, this model of printer is not for tinkering. Of course I encourage you to voice your needs but don't get disappointed if sadly you don't get the response you are hoping for. I sincerely wish you will get better answers than I did so if you do (fingers crossed) please do keep me posted!

Oof... back from the grave and sadly for a bad news : no news. Honestly at that point when people ask about the UM2+Connect I suggest it as a not fuss plug&play 3D printer. If they want to actually tinker, go the Pruza way. I gave up on this. Still happily print with it but I just don't tinker with the device itself.

No worries it happens. Take care @kupfeli and welcome to the forum. PS: yes it's great hardware leading to top quality prints.

@kupfeli I'm genuinely confused here. Are you suggesting ssh should instead be disabled on other models? PS: I would consider unearthing a 5 months old topic bad etiquette if it's not actually helpful.

Yes that's also my understanding but the pause button on the screen does somehow affect the machine so somehow it must relay the request to the motors..?

I understand, a delicate balance indeed. I'll try to attend tomorrow. From the link you shared I was surprise to see in firmware 1.5 "New feature: Change material while print is paused. It is now possible to pause the print and to swap out a material"as this seems to be exactly what would be needed in this specific case. Is it a different mechanism than Gcode? PS: I wish I could subscribe to update to https://support.ultimaker.com/hc/en-us/articles/360017358580-Ultimaker-2-Connect-firmware-release-notes

Thanks @CarloK, exciting to hear that this will gradually come. Is the roadmap public and if not is there a way to get notifications when new feature on a specific model, here the UM2+C, gets integrated?

Unfortunately it is different and so far, despite being newer, has less features.

Thanks @Smithy for the confirmation, this is indeed what I meant by my edit. I believe it's important for everybody interested by that model to be aware of at the name "Connect" my lead to think otherwise. PS: what's "DF" in this context?

Thanks I haven't verified but and the latest August reply "Pause at height is currently not supported by the firmware of Ultimaker 2+ Connect." makes me believe this isn't an option here. Have you tried it on this model?

Sending prints via LAN even while Internet connection is down? But I imagine that's specific to the UM2+ Connect as others can probably send gcode via e.g ssh.

I specified a correct layer (e.g layer 8 of a 10 layers print) using Cura 4.11.0 on an up to date UM2+ Connect. The print finished without error but there was no pause or prompt to change the filament. I verified by sitting in front of the printer for a smaller print. I diff the the generate GCODE with and without the plugin and get : M600 E30.00 L300.00 X0.00 Y0.00 ; Generated by FilamentChange plugin which seems correct. Does the UM2+ Connect firmware support the M600 instruction? If not (which based on previous discussions here wouldn't be surprising) is there a practical alternative to do so using less specific instructions?
