    Printcore not recognized

    I haven't tried cranking on the screw to see what happens so I'm not sure if that would be possible. In general the screws on an UM3 are tightened fairly "loosely". For the head it's 0.3Nm IIRC. Doesn't feel like something that would happen though unless there's very little margin for error for the spring fingers of the contacts in the head. I can't say I've had any customers with this particular problem so it's a bit difficult to diagnose without getting my hands on it to be honest.

    Printcore not recognized

    Yeah, I think the cable would be my first suspect as well. And by cable I mean more the contact and/or the individual pins in case one of them has managed to work itself loose. It's unlikely you managed to damage both cores so I would probably rule that out. And it's not really possible to assemble the head with the print head board in the wrong position causing a bad connection. And from the sounds of it, it's happening when the print head is homed, when there's the most stress on the cable.

    Multiple holes and layer skips within model - HELP

    Is this a solid model or is it a thin shell? I'm guessing that latter and that the shell is thin enough in some spots that Cura can't quite fit a full line width in there. It's also a good idea to look at the model in x-ray mode and look for any red spots that indicates issues with the model.

    CPE / PETG terrible first layer & surface quality

    Have you tried letting it keep printing? How the first layer looks doesn't really matter in 99% of cases since it immediately gets hidden by the rest of the print. To me it looks like the first layer is slightly too close which causes some plastic to squeeze out on the side of the nozzle. I would try going back to defaults and letting a whole print complete (you can print something smaller obviously to not waste too much plastic) just to check if the other print issues stay or go away with the defaults.

    Soluble Filament not sticking to bed

    PLA can usually by printed on a clean (squeaky clean) glass plate. Personally I tend to use glue as it can be a bit more forgiving because I'm lazy.

    problem with second layer

    Unless I missed it you didn't mention what material you were using? Are you using a material that is sensitive to temperature and using a high fan speed on the second layer perhaps? Just a random thought.

    Ultimaker S5 | impressions & opinions

    Disagree all you want, the problem is that some companies NEED this functionality, it is just that simple. It's a question that has been popping up regularly since the UM3 was introduced.

    Mailing list or forum for developers?

    Just make more accounts, easy. In the mean time I'll help by adding another one ("like" that is ).

    UM2 + build plateis not stoping at he top

    Could it be that you've installed the UM2+ Extended firmware on your printer by mistake?

    View print steps option

    You might also need to force windows to use your dedicated GPU for Cura. You can do that in the Nvidia control panel (right click desktop -> Nvidia control panel):

    Additional cube model printed

    Another purpose of the tower is to make sure the nozzle is fully primed which may, or may not, make a difference depending on what and how you're trying to print.

    Printing with no infill.

    I think the closest setting that would be helpful in this sort of situation is "Hollow out object" which will make the object hollow so you can use support on the inside. For this particular model I don't think it would do much good though. But I thought I'd mention it anyways.
  13. What type of scale are we talking about here?

    Cura not slicing.

    To make sure you're truly back to "zero" with the install, go to Help -> Show Configuration Folder. The folder containing all your personal settings for Cura will open. Close Cura and then remove everything in that folder, once that's done you can restart Cura again. This should have you back to factory defaults so to speak. This usually fixes weird issues.

    printer export/import

    My bad. I tried something that appears to work, but not 100% sure it's reliable. I added a machine I didn't have, a Prusa in this case, I then edited the start gcode for that printer and added a word to it. I loaded a model and then saved as project. I then removed the Prusa-printer and restarted Cura. I loaded the project file, the Prusa machine was added and the unique word was present in the start gcode. So maybe a workaround?
