Re: Printing as a solid when it should have an open top

I loaded this in Cura 4.5 and messed around a bit. Initially when sliced, it had infill throughout, including the cylinder, so yes it is printing as a solid. When I dropped infill to 0%, the layers look ok until 101 where it starts covering the top. Definitely a Sketchup issue. I had similar issues ...

Re: Cannot Believe EveryOne is on Stay At Home Orders

Sorry. While I am staying home, I am still working. 90% of my job can be done remotely (installing new hardware in the rack requires office time, but everything else is remote). Plus, we're in the tail end of a major release push. My workdays are ~7:30am - dinner, with a few meetings after 9pm with ...

Re: How to Reduce Wall thickness

Layer height will have a big play here, along with hot end temp. Go with a finer layer height and a higher temp (+10C) and you should see better results. You may also have to figure out a way to do some annealing . You can usually find a cheap toaster oven at a thrift store that works perfect for sm...

Re: Feasibility of printing this part

Yes, if you have the skill to model it. Printing is the easy part. For the best detail, use the finest setting. It will print a lot slower, but it will come out very nice. I'd print it upright with supports on the inside (if needed).

There are plenty of examples (like this) on thingiverse.

Re: How to Reduce Wall thickness

There may be a reason to keep the mask thickness as it is. It helps reduce potential layer gaps, and improves strength where it is needed. Do you have a link to the STL?

Re: Sequential Printing

I can't change the SW to think the gantry isn't an issue. So I put it back to 180. If the print head dimensions are correct, Cura will draw a shadow box around each object, and not allow the shadows to touch. If the shadows overlap, then one of the touching models will be removed.

Re: Sequential Printing

I think that was the default. When I set it to the real height when the nozzle is on the build plate (~35mm), it refuses to print. This actually makes sense in some respects, because the SW is designed for printers like the Ultimaker series, where the gantry is a fixed height and the build plate mov...

Re: Sequential Printing

I just ran a quick experiment to see if my 3DP-17 would do it, using Cura 4.5. I may need to adjust the print head dimensions, but it seems to be ok. I set the printhead dimensions by measuring from the printhead in each direction. Not very accurate, but close.

Re: 2nd Post - Understanding Supports in Cura

So, in most structural architecture, you want the support to touch to prevent sagging during construction and in most cases, those supports become part of the finished structure and are not removable. Where they are removed (say a temporary stud wall to hold up a ceiling while replacing a beam), the...

Re: 2004 LCD ( REPRAP_DISCOUNT_SMART_CONTROLLER )

You could try swapping the displays between red & blue, see if the problem follows the SD card slot. Worst case, you may have worn out the SD slot or controller. Replacement displays are ~$12 on amazon.

Re: 2004 LCD ( REPRAP_DISCOUNT_SMART_CONTROLLER )

Are you using the SD built into the display or the one on the mainboard (newer mainboards have it there due to signal integrity issues). If on the display, you may need to shield your cables to the display. Try wrapping them in tinfoil as an experiment.

Re: how to fix this kind of quality issue

I bought my son the same printer several years ago when we first got into 3D printing. Some of his prints were good, but then the quality went downhill. One of the biggest issues he had was the belt drive Z axis which started doing exactly what you are seeing. Then his printer decided to embed the p...

Re: Why is not Slicing?

Also, if your object is fairly low and flat, don't bother with a brim. Just use a skirt. The brim is used for models with very little first layer surface and decent height. Think of a tube printed on end. The skirt with 3-4 lines will create a steady flow of filament (prime the printhead) for the ac...

Re: 1st Post - Understanding relationships in Cura

The "Shell" is the outer layer of the print, and the settings relate to its thickness. Settings like how many lines are used to form the shell for example. This can help with surface strength (rice paper vs brick wall for an extreme analogy). For the best bottom surface, make sure the prin...

Re: Selection of part in Creality Slicer

So, using your example stl files, when I mouse over them, they highlight individually (as it appears in your 'example layout.png' file). I can select and move by holding the left mouse button and moving one object. I can also hold the right mouse button and change the camera view perspective (tilt &...
