Afaik the app is indeed not maintained anymore by Ultimaker although it is still available in the Google Play Store. The current recommendation is to use digitalfactory.ultimaker.com on your mobile device instead.

You can change the theme in the Cura configuration. There is a light and a dark colorblind theme too there.

Does it change if you increase the frame light?

The question is how sensitive you are to an electrical incident, depending on the quality of the PSU you use. Be aware you that if you use a different PSU than the type Ultimaker uses you do that on your own risk. Imo a decent printer should be driven by a decent PSU. But it's of course your decision. Be safe.

The PSU of the Ultimaker Original+ as well as for the heated bed upgrade of the Ultimaker Original is the same PSU as the Ultimaker 2+ and the Ultimaker 3 comes / came with. That means you should get it from a well-sorted Ultimaker reseller. Apart from those locations: if you turn the PSU you will see the type label from Meanwell. That should give you enough information to search it on the internet so you can buy from your preferred dealer or shop.

That logo is usually only seen at startup. Does your printer boot until you get the main menu? You need to reset all printer settings - something did not initialize properly after the firmware upgrade. If your printer does not come up to the main menu (give it 15-20 minutes please), switch it off, disconnect the material station bus cable and switch it on again so it starts as a standalone S5. Then you can do the reset.

I heard a rumor that there is a pandemic that force also Ultimaker into the home office which might delay new things... 😉 There is one new UM product for sure this fall: Ultimaker Essentials. edit: The launch of the Ultimaker S5 was btw. in May 2018, not fall...

I do have an idea, yes. 😉 But it is up to R&D and UM Testing to decide that a firmware version is stable and can be published. From that moment it does only take a few days maybe until your printer will indicate that the new firmware is available. The only thing I can say is that if things go as planned then we are closer to the next version than we are away from the last one.

There is no legacy Cura version 15.0.x as the scheme for numbering was "year.month.counter". For 15.04 there were multiple versions which did not all come out in April 2015. I guess this must then be 15.04.6 😉 That was the latest legacy Cura version iirc.

The BB core will likely clog. I recommend you wait with further "tests" until the next firmware is out. It will bring some significant changes especially for PVA in the Pro Bundle. Also please use bay F and E for PVA in printcore 2. If you do not have extremely new PVA also try to anneal the PVA and maybe cut of the last meter after a while not using it before the next print in order to minimize likelihood of breaking in the main feeder.

Yes, it is the same firmware - currently 5.2.11.

Yes, any preferred reseller should be able to provide new sliding blocks. As for instructions, there is a Video from FBRC8, which shows how to assemble the sliding blocks. Changing the block shells in-situ is possible but does not work that well as with removing the axes.

That might be an explanation why you don't see them. However, this is where e.g. @nallath might want to step in.

Depending on what print core you have mounted they might appear greyed out with a red exclamation mark symbol as they need the CC 0.6 printcore. Cura should send them automatically if you are connected to the printer through Digital Factory (network or cloud). And it will show you a small dialog at the bottom center (see attached picture). That happens after Cura startup. If it does not happen, something is broken in your Cura installation. The only way to get it running is afaik to "nuke" Cura, i.e. to clear all profiles and let Cura create a new installation. You can achieve this by deleting all content of the parent Cura configuration folder (menu help->show configuration folder and then two folders up "cura"); the better way than deleting is to rename "cura" into something like "cura.old" so Cura doesn't find it anymore but you would still have an easy way to go back.

The sync should happen automatically. Does it sync a newly downloaded material from the marketplace? When you test it, make sure the material is compatible with the UM3.

The material is still linked to its origin material and therefore has the same UUID. You need to unlink it so it gets its own UUID. Only then it is uploaded to the printer.

Just enable support generation. If you want more information about support settings and tools, check out the Ultimaker Curea support pages, e.g. https://support.ultimaker.com/hc/en-us/articles/360012612779-Support-settings

Your topic title suggests you have a S3 to sell. However, the S3 was just introduced in fall 2019. Could it be it is an Ultimaker 3? Also, currency, your location / locations you could ship it to, some pictures and details about print core usage, etc. might help you finding a buyer.

I think what @fieldOfView described was essentially the process Ultimaker went through when designing the Ultimaker S5. The electronics of the S5 are derived from designs that were originally on the Ultiboard of the Ultimaker 2+. The feeders are an improved version of the Ultimaker 2+ feeder (having a different lever and a filament sensor).

Such requests already exist. E.g. https://github.com/Ultimaker/Cura/issues/6072

I can't give you a definitive answer as I'm not a dev. But it happened to me exactly the same way.

With the print core cleaning wizard, yes. But you can also do manual cold pulls by adjusting temperature manually and then you can also use other filaments.

No, due to the 6-to-1 junction in the material station feeding goes only in one direction. The feeders on the printer are responsible for continuously feeding material through the print cores while the prefeeders in the material station work in steps and make sure the main feeders always get enough filament.

The filament runout sensors in the Material station are just before the prefeeder in the Material Station so the remaining filament can be retracted back into the Material Station compartment. As you realized there are about two meter of filament left which you can e.g. perfectly use for performing print core cleaning.

The Ultimaker 3 (not S3) was indeed the last Ultimaker printer with open hardware. I would not expect the S line hardware to become open. May I ask what do you see as advantage of open hardware in a professional 3D printer?
