There are plugins in marketplace for different shapes. Or you can model your own and bring them in to use a a blocker.

I ended up using UltiMaker Polypropylene Natural for my prints. Images of a section of the part printed to check for function and fit. Wall section is 0.5mm. I had to use a gyroidal support pattern of 80%, and also a support interface for roof and floor. The default zig zag support didn't work where the paths crossed over each other due to the material being so soft that the crossing layer pushed the lower layer out of position.

What would be the most suitable to printing prototype blister pack packaging that has a flexible hinge on it? PP, TPU95? Colour or transparency is not important as we're just checking for fit and function.

We're looking at printing abrasive filaments with both cores on our S5. Is there a lower cost alternative to use seeing as we need two of them?

Thanks, this work OK for this part.

Simple question I think. Why is my support blocker not blocking all the support? Is leaving 2 sections of support either side of the hole. Thanks. UMS5_support blocker test.3mf

Great idea! Just need to untick the connect infill lines to stop the infill on the slope.

If you make the Wall Line Count, Top Layer & Bottom Layer all 'zero' and untick 'Connect Infill Lines' you get the bellow outcome? Is this what you are after?

@Imaginables3d @MariMakes I finally found the problem that was causing the ER65 code. On very very close inspection of the g-code I found that the layer was being duplicated at line 2201 for some reason. This put the print core at the same Z position on the layer it just finished thus not allowing any material to be extruded, and in combination with the flow sensor and the de-coupler on the material station it sensed that there was a problem. Disabling the flow sensor, or not using the material station prevented the layer error from being detected. This is why it always happened at the same spot no matter what bay, extruder or filament I used during testing. This duplicated layer doesn't show up in preview in CURA. It's only because I have many years experience programing and running CNC machines and back plotting g-code that I found it. The back plot showed the Z not changing is what caught my eye. I've not been able to reproduce the the code error in CURA 5.1 https://ncviewer.com/ AbortedUMS5_Printed_holder.gcode

Same here with our S5 also. Was working OK until a few days ago. Cannot print anything.

Your attached images look just like the issue we had with too much moisture in our PVA. I put it in an oven over the weekend at 55°C and then store it in a sealed bag with desiccant. No more problems now. Hope this helps.

Thanks so much for trying the G-code 👍. I'll raise a ticket and see what happens.

Hello @Torgeir, I did check the fan (all clean), the feeder and also did a print core clean. Thanks.

Hello @MariMakes, I tried printing again from the project file I attached above today and like you, have found it prints OK. I also tried reprinting the aborted one again with the same result ER65 in the same place. (Could you try the Aborted G-code file on your S5?) So I went back and downloaded one of the aborted jobs from my history in the Digital Factory and had a look at the G-code where the print failed. I then compared the G-code to the one that works. This is when I noticed the the failing code has some extra lines in it with M204 commands at the position that it stops extruding? Does anyone know why this would be? Thanks.

Thanks for the reply @Torgeir. I'll keep all the suggestions in mind if the error returns again, as I still don't understand how it could stop in the exact same place 3 times in a row.

Hello @Torgeir, I did look at the support page, but I think the error was a false flag. As I could abort and then restart the print immediately and it wold stop in the exact same spot (about 30min into the print). I tried this 3 times and on the third one I watched very closely, as soon as it moved to position to start the 3rd layer I could see that it stopped extruding and the error came up after about 10sec. And also rotating the project 90° resolved the issue? So I have no idea what caused the problem and how to avoid it in the future? Normally I start the print and go home but this time I was delayed and noticed it had stopped. I've attached the project file this time (I think). UMS5_667164299_UMS5_Printedholder.3mf

Anyone?

Do yo mean the Starts? Just untick the check box in the dropdown menu.

I started a print on our S5 and at the start of the 3rd layer it stopped with a ER65 after about 30min. Everything look good up to that point. I aborted the print and started again and it stopped at the exact same layer and position. I tried once again with the same result. What is going on? Attached are the files for the part. Marked in the image is where it stopped each time. Thanks. I ended up rotating the part 90° about the Z axis and it printed fine.

Did you do the "Sync with Printers"? It took me a few attempts to get this to work, but all good now.

I've the same question, looking forward to an answer.

Changing from Tree to Normal support gave me a much better outcome, image below. 👍

Thanks for the reply's, I will try normal support and see how it goes.

3mf file attached. The model is trimmed as above the supported area it comes out OK. I have another spool of PVA on order plus some Breakaway to try. Thanks. UMS5_MX3294_3D_Print.3mf
