The link was for the UM3 and it may also be that the tool does not fit. But the main point is that the distance is about 14mm. With this distance you can be sure that the capacitive sensor works properly. I don't think it's important that it's exactly 14mm, but approximately. If this does not solve your problem, please contact your reseller, because this behaviour is not normal and should be solved by the local support without problems.

Good luck and I hope it works out. Such a head in spiral mode surely looks great.

I love the bed leveling at the UM3 and S5. I've never had a problem with it and it's reliably performed at every print. This has the big advantage for me that I can take out the glass plate or change it without controlling the leveling afterwards, the printer does that for me. That's also one reason why I hardly ever remove the glass plate from the UM2Go because I find manual leveling tedious. I know that others see it completely differently, but for me it makes my job easier.

The recommendation is in principle ok, because different materials have different pressure temperatures and there can always be a rest in the nozzle. But if you clean the PrintCore regularly or after every change from one type of material to another, i.e. with hot/cold pulls, then I don't see any problem. I don't use dedicated PrintCores and also don't do a Hot/Cold Pull very often and don't have any problems with it. But that doesn't mean that this is the correct way. I think this is rather a question of faith how to handle it. With dedicated PrintCores for every kind of material you certainly don't do anything wrong, if it's really necessary, I can't say, but I personally haven't noticed any disadvantages after one year. When a nozzle is worn out, you can see from the print quality, as the nozzle no longer has the intended diameter and has become wider. So far (1 year) I haven't seen any wear on my PrintCores.

I would say you print too fast. 90mm/sec is too much and with the small area at the top the material has no chance to cool down. If you print slower, you might be able to go down a bit with the temperature, but you would have to test that. In addition, the model is not easy to print in spiral mode. At the head end you have a massive overhang and since you only have one perimeter, little contact area. The material in this region is almost printed in the air. So I'm not sure it'll print the way you think.

It is not normal, AL works for fine on my S5 without any issues. But I have one idea, check if the height of your bed is round about 14mm. This was often a problem/fix with the UM3 and I guess this could also be a problem with your S5. Here some more details and pictures what I mean: https://ultimakernasupport.zendesk.com/hc/en-us/articles/115005705806-Why-Isn-t-My-Active-Leveling-Working-

When you already have cleaned your nozzle, but still have extrusion issues, then I guess there is something wrong with the feeder. Check if the filament is needed properly or if the gears in the feeder slips and don't push the filament forward. Another possibility is, that your filament is tangled on the spool and cannot be unwinded during printing. Which printer do you have? Regarding the brim, I have currently no idea, but it can help to upload the Cura project file here. Save it as project, then we have all the settings you use.

Often these are only very small openings which are almost invisible to the naked eye.

You have to design the slots bigger, maybe 0.4 or 0.5, you have to try it. The slots behave like holes in an object, they also become smaller when printing.

It has nothing do to with CPE and can happen with all materials. Due to the printing process you cannot be 100% sure that you have a watertight object. You can use more perimeters, print slower and hotter to ensure you get a good layer bonding. But a very small area of i.e. under extrusion can be enough to be not watertight.

Thanks! And no, for the S5 it is not possible to turn off the leveling. So maybe I give it a try, I like the idea behind the switching system and I hate to apply, glue, Dimafix, Magigoo or whatever in the meantime.

I would say you print a way too fast and too cold. So you should adjust these values first, before trying something else. Try your test print with 50mm/s and 200° and check the result. 9.6mm3 is a lot of material which has to be melted in only 1 sec.

I am thinking about buying the Filaprint Switch Plate. One question, is the auto leveling still working with it and without damaging the surface of the build plate?

You find it in the Cura Help menu or directly via this link: https://github.com/Ultimaker/Cura/issues

In general it is hard not to make a Cura update, because there are some bugs in every version, which are fixed with the new version. But with the new version there will be other bugs. You have to keep an overview of the bugs to decide which version to use.

Basically yes, with UM ToughPLA and the default profile, it prints a little slower, but I haven't compared both profiles (PLA, ToughPLA) But I also used PolyMax with the generic PLA setting without problems.

Has anyone already created a bug for this on GitHub? Because only there can we make sure that someone is looking at it.

There were some posts the last days with similar support problems. It seems it is a bug in Cura 4.2.1 Try to downgrade to 4.1 which should work fine.

Ja gibt es, heißt glaube ich Support Roof (im Deutschen musst du schauen), dort kannst du dann auch den Extruder auswählen der es drucken soll. D.h. du stellst Support auf Extruder 1 und das Dach auf Extruder 2.

You can use PLA+ from other brands, like UM ToughPLA or PolyMax or ..... It is not related to the properties of a stronger PLA, because ToughPLA prints like PLA without any problems.

Yeah, that sounds a lot like the problem. If you really need the toughness of the PLA+, then there are many other manufacturers that have such materials.

I know you're struggling with it, but when you see the finished model, you almost can't believe it. Don't be impatient and look forward to the incredible result.

Wobei es eigentlich egal ist, Octoprint stellt ja auch nur einen Stream zur Verfügung und macht sonst nichts damit.

Yeah, that would explain it. Thanks for the update.

Good decision. I hope that solves your problem.
