Plate scraping after I leveled bed perfectly

Progressively reduced speed for thin and tall print
GregValiant replied to Jerome85's topic in UltiMaker Cura
It is an easy thing to do in post-process so that's where it is. As you saw - there are many post processors capable of a variety of effects on the gcode. If they were all implemented directly in Cura then what is already a cluttered interface of over 600 settings would be completely unwieldly. -

Go to "Extensions / Post Processing / Modify Gcode" and then "Add a Script". -

You can use the "Change at Z" post processor. The "Change Speed" option will insert M220 lines and all speeds will be affected (print, travel, retraction, prime). The setting is for a percentage so if you were to change the speed to 75% at say layer 700 and then use another "Change at Z" to make it 50% at layer 1200 you could progressively slow down. A second option is to change just the "print" speed. If you use that then the travel speeds would be left alone, but you don't have any in vase mode. Another post processor "Limit XY Accel and Jerk" will be available in Cura 5.7 but it's for bed slinger style printers. -

Then you really need to go over the Reddit and see what help the Ender 5 (or 3) users group can help with. -
On that model there was a pause coming up. If I would have had to manually pause a layer early it wouldn't have hurt anything but it made it to the pause. I was kind of proud of my guestimating ability there.

There are a few bug reports about this over on GitHub. I haven't seen an exact cause of the problem. It seems to be an interaction between a couple of different settings ("Flow Equalization Ratio" and "Initial Layer Print Speed" seem to be a couple of them "Print thin walls" might also be involved). I do have a post-processor that will fix the over-speeds in the gcode. If you think you need it or want to try it, let me know and I'll post it here.

No. Cura works by linetype. Inner-Walls will be completed before Outer-Walls (there is a setting to change that to Outer first). Cura is going to print that grid as if it was made of a bunch of boxes. There are a lot of "walls" in that model. Your Wall Speed of 25mm/sec is a bottleneck. If you print everything at 50 you can get the print time down to about 41 minutes.
-
You need two models. Leave a cavity in your model where you want the "filter" to be. Design a cylinder to exactly fit in the cavity. This will be the filter element. Bring both models into Cura and move the "filter element" model so it is exactly in position. With the Filter Element active, in the "Per Model" settings choose Wall Count = 0, Top Layers = 0, Bottom layers = 0, Infill Pattern = gyroid, Infill Density = 15% (or whatever you like).

Because heads are rarely "round", it isn't really the diameter. I suppose hat size would be an "equivalent diameter".
-
Hat size in English units is "circumference / PI()". Metric may be the same sort of thing. Take a piece of common 1/8" solder. Wrap it around the persons head at the level that the hat will sit. Tape the ends so they don't move and be gentle with the "form" so it doesn't change shape. Lay it gently on the floor with a ruler next to it. Take a photograph. Load the photograph into the CAD software of your choice. Scale the photo until the ruler in the photo is the correct length. Some heads are round, some are oval, and some are apple shaped. This one is mine. (If anyone makes a comment about the fact that it's empty I WILL FIND OUT!) When I have this scaled so that a spline on the shape is 23.18" in length then I know this will fit my 7 3/8 head. When you get done, you can make a helmet. This is my personal helmet. 160 LED's 3 LED PCB's, a PCB for the siren and a PCB for the bell, and a PCB for the MP3 Player, and 2 speakers. It is powered by 6 AAA batteries. It weighs about 2lbs. It contains no printed parts. I figure it's about a $5000 hat. Yes, that is a molotov cocktail on the shield. "Richards Wild Irish Rose" bottles made the best. And if that isn't enough, here is the one I built for my Scottish brother-in-law. He fishes, he golfs, he hunts. He requested that it play bagpipes. I got to pick the song.

Cura Generating Supports Beside Model
GregValiant replied to Adventurehill1's topic in Improve your 3D prints
@gr5 I don't think the OP has to go through that for this project. Just set "Support Horizontal Expansion" to 0.0 and turn off "Use Towers". -
When i was print the file it is not print in centre
GregValiant replied to nitin24879's topic in UltiMaker Cura
Welcome Nitin. You did not mention what printer you have. Many printers have the "origin" at the left front corner. Some printers (mostly delta printers but one or two others) have the "origin" at the mid-point of the bed. The setting is "Origin at Center" and you can find it in "Manage Printers" and then "Machine Settings". While you are in the Machine Settings make sure that the build plate size is correct. The size determines where the mid-point is and so can effect the location of a print on the bed. -
Can only get Combing to work in Surface mode
GregValiant replied to Wingspanner1968's topic in UltiMaker Cura
This slice was with "Spiralize Outer Contour" enabled. "Travel Moves" is turned on. I recognize the design style and intent. This model has been designed to print in spiralize mode. The internal ribs are exactly the correct width to provide an up-and-back movement so the nozzle never has to stop. Another indicator is that the bottom starts out narrow, then widens but isn't a sharp step, it has a chamfer. That allows it to print in spiralize (spiralize doesn't do roofs) and will not require support. The support for that notch on the bottom is a separate structure. That means Cura must travel to it and so there can't be true spiralize until the two islands join at about layer 15. Once it gets above that the nozzle just keeps moving and extruding so travel moves aren't required. EDIT: I would strongly suggest that you use a skirt or brim rather than a raft. Rafts generally are harder to remove than a brim, and the print can be damaged during removal. I do have a handy-dandy post processor that you could use to print the top of the raft with PETG (if you have some laying around) which PLA doesn't stick to very well. The raft would come right off. If you would like to try it out I'll post it. -
Can only get Combing to work in Surface mode
GregValiant replied to Wingspanner1968's topic in UltiMaker Cura
Airplane parts (and some boat parts) are different and often require workarounds. Use the "File | Save Project" command and post the 3mf file here. Someone will take a look. It looks like you have "Avoid models when traveling" enabled. That might be causing a conflict/override of the combing setting. Combing might say "travel on the walls" while "Avoid..." is saying "get off the part".
