Question about printing times
Update 10.02.2023: I remixed the rotor with the toroidal design :) Feel free to test ist out! https://www.thingiverse.com/thing:5846249 Update 23.02.2023: NEW PULLING RODS! Some had proplems with a breaking pulling Rod. So I beefed up the old one (Classic+) and also designed 2 totaly new ones (Ergon...
Hello all. I am very new to this but it is all very cool to me. I ran into a problem and I am not sure how to troubleshoot it. I downloaded a simple pull string helicopter off thingiverse. After running through the slicer software, the estimated build time is 131 hours. Relative to it’s size this seems insane. If I “run the simulated build”, there are long holds on one of the interior walls. I am hesitant to just “try it” and see if the pauses are a software thing that does not translate to the hardware. I am not sure how to break it down from here. Any advice?

You definitely don't need a layer height that low for something like this. Even still, you've got something set up weird because at a normal 0.2mm layer height it's showing just under 4 hours to print everything but the pull rods (only because I'm too lazy to split the STL apart right now.) Try resetting your build settings or start a 'new' project.
13When I switch to 0.2mm the time goes to 83 hours, so I assume there is still some error. What slicer do you use?
1Don't use Creality Slicer, it's just an outdated renamed version of Cura. Download the most recent version of Cura here and your problems will most likely go away. https://ultimaker.com/software/ultimaker-cura/

Can you give us your basic info:
- Which printer
- Which slicer
- What kind of profile
- Which preset (if any)
- What filament is selecte
- did you change any settings
and just posta screenshot of the sliced model that the slicer should show you, makes it much easier to recognize trivial errors like wrong orientation.
11Here is what I remember.
Creality ender 5 s1 Creality slicer High detail profile (Infill % 15, speed 100, nozzle temp 205, bed temp 60, z axis 0.1) PLA These were the default with no changes.
I am not sure what other parameters can be changed.
I will post a screenshot tonight. I did notice that 99% of the time is on the outer wall, this is where I noticed the pauses when I simulate the print.
5I'm sure the official slicer will have a good profile, maybe the speed for outer walls accidentally got changed to 1 mm/s? I don't usually use Cura (that is what their slicer is based on), but I think to change speeds at all you need to hit "show advanced" or something? So if you didn't change anything, that is even less likely.
If it's real pauses (print head stops completely), I have even less ideas what that could be.
When I get back home I can try to see what I get with your settings, probably just resetting everything should also work for you though.

I suspect what's getting you is minimum layer time. In a nutshell, extruding very hot plastic onto a layer that was very recently extruded can result in a runny mess. Minimum layer time is intended to address this.
That said 131 hours seems a bit intense.
What's your layer height? How good is your cooling? If you crank your fan, you might be able to decrease minimum layer time.
8Just to add on to this, if OP is printing this standing then it really should be laid on iits side, so that the hole in the handle is facing up & down, not sideways. Looking at this print that's definitely how it should be printed. Vertical not only runs into layer time issues, but it's a tall, thin object with loads of layer seams in the middle. It will be extremely weak. Lying down the layers run along the length of it, making it stronger. If the hole is sideways, then one side of the handle makes a giant bridge, which could fail the print entirely or need lots of supports.
I imagine the designer very intentionally made it to print on its side.
Oh and put the embossed arrow facing up, assuming the other side is flat.
7Layer height is 0.1mm. it's odd, because it happens on specific curved areas. There are no pauses on other areas that were recently printed.
4A good rule of thumb is to just always use 0.2mm layers unless you have a very good reason not to.
That being said, this doesn't explain your truly nonsensical time prediction. It would just be double, since you have twice the layers to print. Like someone said, a few hours would be reasonable, certainly less than a day even with very fine detail.

Something else to check is your infill percentage. Make sure you don’t have it at 100% (unless you absolutely need to build something completely solid). Another thing to check is your print speed. Too low and it will take a decade to print something simple. Too fast and it cause your print to fail. At this point we will all be throwing spaghetti against the wall. Can you share a screenshot of your settings?
6Perry the helicopter?!
5Every time I see this contraption, I can't stop to think about Gardena making propellers. Due to the chosen colors.
5I'm literally looking at my garden hose roller thing and yep, can confirm.
