I would like a little clarification of what Cura calculates to be a hole. So far, I have found that when looking down on the model in Cura, a hole can be any shape. Round, oval, square, or even just plain weird. And everything I have seen so far has no bottom and no top. I would guess, however, that since Cura slices layer by layer, a hole would be any space that is enclosed on all sides in the layer being sliced. If that is the case, how would a horizontal hole on the side of a model, like a screw hole, get expanded since it would be open on one side? Thanks. Wayne

You are correct, but there is a workaround for now. Use file manager to select all the files you want to add, and then drag and drop them into Cura.

The 5.4 beta won't allow loading multiple files at the same time. For example, - navigate to the folder with stl files. - select first file - Move cursor to last file - shift-click last file the first item is DE-selected and the last file, and only the last file, is selected The same thing happens with ctl-click Computer is a Windows 11 laptop, and this process works with all other applications, etc.

ooooooohh yeeeaaaah. Minimum layer time. I had forgotten about that one. About flow, I've been printing for about 5-6 years and I have NEVER heard of any other technique besides cubes, either single or sometimes double wall, to calibrate flow. The funny thing is, the process ends with something like "after completing the calibration, verify with an actual print and adjust accordingly." Why not just adjust accordingly to start with? This is the first time I have used the cubes in quite a while as I have essentially been doing the "to start with" method anyway. Thanks for the info. Case closed. Wayne

Sheez. Already have an update. I just happened to watch this one start printing. The first layer printed at the 30mm/s as defined in my Cura settings. As the second layer started, I heard the fans come on, and the print speed DECREASED even further. Like maybe 10mm/s.

I am working through some calibrations for my CR-10S and one of them is printing a 20mm single wall cube (no top, bottom, or infill) to calibrate flow. Along with calibrations, I am trying to determine the printers top print speed that still yields good prints so I had the print speed set to 100mm/s after the first layer. I noticed while the cube was printing that the speed seemed to remain very slow, and looked like it kept the 30mm/s first layer speed for the entire 20mm cube height. My first thought was that I had Spiralize Outer Contour checked, but it was not. So does printing a single wall model cause Cura to invoke vase mode? Currently running 5.2.2, but I think I have noticed this before on some older versions. Wayne

I haven't had this issue for quite some time. Maybe as much as a year. Even when I was having the problem on occasion, it was so minor and easily circumvented that I quit monitoring this forum for a resolution. There have been a few new versions of Cura since then, so I just assumed it had been resolved.

Until recently, if I had a model created using Fusion 360 loaded into Cura, I would get a notification in Cura if I altered/saved the model in Fusion 360. That doesn't seem to be happening any more. No notification of an updated model in Cura. I don't know if this is a change in Fusion 360 (just got an update today), Windows 11 (constant updates), or Cura 5.1 (no changes I am aware of), but I would sure like to get that capability back. Where would I start looking to diagnose this? Thanks, Wayne

Thanks Posital. I have been using Arc-Welder since it's beta, and of course I have added the Cura Plug-in. I asked the question here before Arc-Welder existed. Wayne

I have had this happen several times for a while now. When it happens, there are NO parameters that are red ( At least no VISIBLE parameters). As BenjaminS94 says, change ANY single parameter, and change it back and you will be able to slice. Change temp, change it back. Change speed, change it back. Change the number of walls and change it back. It does seem like you could literally change any single parameter, and then change it back.

Yeah, I know all about that gap and it can be quite irritating. But in this case, the gap is caused by the print head zigzagging the perimeter instead of printing a straight line. It moves outward what looks like a line width every 25mm along the 95mm lengths instead of printing it as a single straight line. And just for laughs that I probably shouldn't mention here, I had about 5 pieces laid out including this one. I made all of my settings, sliced, and had an estimated print time of about 6 hours. When I increased the print speed from 60 to 80mm/s (no other changes at al), the estimated print time INCREASED to over 1 day 8 hours. 🙂

Quick addition - Cura 4.12 beta does this too.

I have been using 4.11 for a while with good results. But the last few days there is ONE piece that doesn't print correctly. It is a trapezoidal shape and there are two sides that do not print as straight. In the picture, you can see where there are gaps formed when the nozzle moves outward at several points. There is another piece that this one mates to, and has the exact same dimensions, but it does not have this issue. I have tried turning it over, and also rotation it around the Z axis in several positions, and nothing helps. I also used two different printers. As a test, I sliced it using PrusaSlicer, and it printed fine without the gaps. The piece was modeled with Fusion 360 (stl file attached), and it shows the entire side of the piece as one continuous face. E5+ Filament Guide and Runout Sensor - Post Cover.stl

No, nothing in particular. To be honest, most of it would probably be soooo far above my head anyway. I was mostly just curious since FormerLurker's github page doesn't have any updated release since February.

Thanks for the reply. Now I just need to find out what some of it means. 😁
