Never mind, I have found that Cura will still slice and print, even if the values are marked in red as erroneous!

This thingy https://www.thingiverse.com/thing:4256347 is supposed to deliver a flexible hygiene mask holder by avoiding to print the top/bottom layers. The STL has tops and bottoms, but the instructions say to print it without them, such that the hex infill will become visible. With Cura, however, I cannot find a way to do that. If I set Layer thickness to zero, it marks it as error. Is there a way to do that?

I mostly have tPLA+PVA. Contrary to expectations, it's the tPLA that gives trouble; the PVA is just fine (I dry it regularly). And it's real underextrusion, meaning that turning off the flow sensor will result in a ruined print... 😞

I am frequently getting the dreaded message: "One material appears to be empty" (which in reality means: "the Hall sensor in the feeder is not detecting any filament movement"). I have cleaned and inspected the feeder, replaced the Bowden, and of course checked the filament. Can this be a sign that the printhead is worn out and needs to be replaced?
-
Thanks. Here we go: https://www.dropbox.com/s/e5840y68p3322ek/2020-08-25 16.53.26.mp4
The rattling noise comes during movements along the Y-axis (not the X-axis), and it is audible during unidirectional movement. Therefore, I don't think it's a loose rod.
-
Thanks a million Erin!!! BTW, may I accede to your kind help again with a related question? Since a few days, the S% is making rattling noises. Rat-rat-rat-rat-rat-rat at approx. 2-3 Hz frequency. It seems to come from the upper front-left corner, maybe from a pulley. Does this ring any bell?
-
Thank you, this is very helpful! However, it begs the question of what is the least-cumbersome way to remove the guiding bars. I guess that it is probably best to
- first uninstall the the printhead and its axes
- then unscrew the side walls in order to take off the guiding bars
- then remove one cogwheel from the guiding bar,
- then slide in the black slider?
right? 🙂
-
The UMS5 has a black thingy (don't know how it's called) into which the axis snaps. It no longer snaps though. Maybe the side retainers (made of plastic) are worn. Might somebody explain to me how to remove and replace it? 🙂
I would be immensely grateful!

I had one feeder replaced on warranty, and that eliminated the issue. The filament channel within the feeder can become worn out pretty badly: the knurled wheels of the feeder are of hard metal but everything else is wobbly plastic. It would be nice if some third-party would be a more sturdy replacement feeder, all in metal.
-
OK, thanks. I thought that my LAN may have a problem, but this is the only device that does that. For a printer in this price class, this is not a great assurance of quality...
-
On long prints, my S5 loses periodically its internet connection (ethernet cable). The first few hours of any print are OK, then I start getting messages on the browser that "the printer cannot be reached" and that "no detailed information is available". That goes for a few minutes, then the printer reappears - for a while - and then it disappears again. The printer is pingable at all times, and the video stream from the camera is always available. I wonder whether I am the only one with this issue.
-
ahhh, great, thanks!
-
How do I configure Cura to instruct my UM S5 to stop after printing a defined layer?
-
Thanks. So, the UMS5 printer will not automatically adjust the temperature, even if instructed that the replacement spool has a different material?
-
nobody really? I tried it now, ToughPLA->PLA. The printer objected with a warning, which I overruled. Let's hope that I will not screw up the whole thing...
-
Let's say, I start a print on a UM S5 with Tough PLA, and I run out of filament at half of the print. Can I go through the filament change procedure, but load something else than Tough PLA? The printer asks me what material I am loading, so in principle I presume that I could do that. But when Cura had sliced and sent off the g-code, it assumed that everything would be printed with Tough PLA. Is that going to be an issue?
-
Yep, that's what I did. But I am intrigued. The design software is Fusion, the parameters are as shown here:
-
Here's what I don't understand. This part is perfectly symmetrical. Why does Cura place a support on one side but not on the other???
-
Since very recently, I often receive this message from Cura Connect. I wondered whether this may be a hardware issue of the LAN network (the printer is hardwired with Ethernet). However the video stream from the webcam continues to work OK even when the printer is supposedly "unreachable". Hence I now suspect a firmware issue/bug. Any ideas?
-
I had posted this in 2018. Now we are in 2020, and the app still does not notify the user that a filament has run out. This is really disappointing.
-
Thanks. Indeed the tensor had immediately popped out but I repositioned it, I think correctly. What I notice, is that the release lever is now a bit harder to operate than before. The tension gauge is at around half. Could it be that it's now too tense?
-
I had a ToughPLA filament stuck in Printhead #1 of my S5, and could only take it out by removing the Bowden from the extruder. I then cleaned the extruder knurled wheel, since I was at it already. After reassembly, I am getting "Material out" errors (note: on the ToughPLA extruder, not the PVA extruder) every 5 minutes. But there is nothing wrong with the material, and in fact I am getting good prints by disabling the flow sensor.
I conclude that I may have somehow screwed up the flow sensor while cleaning the extruder. But what could the issue be? Any advice would be gratefully appreciated!
-
i will then buy quickly the cheap one, before they find out... 🙂

From Digitec.ch
may a defective side fan be the issue?

I am getting very frequent tPLA underextrusion on my S5, resulting in halted prints (if the flow sensor is on) or ruined print (if the flow sensor is off). I have replaced both the prinhead and the bowden tube, and I have cleaned the feeder many times. None of this has resolved the issue.
Now I have noticed that the part of the filament entering the upper part of the printhead has an increased diameter, suggesting that it was partially molten. I think that this may indicate that the temperature creeps![]()
up from the nozzle to the upper metal tube. If true, this might indicate that the side fan is not working. But it's difficult to see the fins of the side fan, even with a flashlight. Is there a way to test the functionality of the side fans?
