  1. Interesting. Does anyone know what the maximum volumetric flow rate is for an Ender 3 Pro with stock hot end? I guess this would vary depending on nozzle size, material, printing temp … ?
  2. Fair enough: - Infill Layer Thickness (When should I consider using this?) - Retract at Layer Change (What's recommended? Why would I want it or not want it?) - Regular Fan Speed - Maximum Fan Speed - Regular/Maximum Fan Speed Threshold (Why would I want to have different values for Regular and Maximum? When would I need this?) - Extensive Z Offset Processing (If it's recommended to leave it off, why does it exist and why/when would I want to consider using it?)
  3. My biggest issue is that sometimes the flyout descriptions for the various parameters give no indication of WHY one might use them. It would be nice if more detail was provided to help the user make more informed adjustments.
  4. I’ll have to look into Adaptive Layers some.
  5. Forgive me if the following feature is already in Cura, but I haven't found a way to do this yet. For example, when printing a 25mm test cube with a 0.8mm nozzle and 0.4mm layer height, the last layer printed is 24.8mm, not 25mm, because Cura only works in full layers. Why wouldn't there at least be an option to print the final layer at whatever height is required to reach the full height of the object? It seems like this would be a nice improvement and an easy feature to add. In order to avoid potentially having to print the last layer at just 0.1mm thick, perhaps the feature could be to adjust the last "x" number of layers to achieve the full height?
  6. Thank you for that very clear explanation. Very helpful.
  7. I use 0.8mm nozzles frequently and often use a 0.3mm or 0.4mm layer height. On some materials, a brim this thick can be difficult to remove cleanly without a lot of effort. I would be interested in being able to set the brim thickness independently from the initial layer thickness. Similarly, at times on parts/materials that are warping, it might be helpful to increase the brim thickness.
  8. Is there a difference between what the Initial Layer Height setting does and what the Z-offset plugin can do? Is there a situation where one should be used vs. the other?
  9. There is a z-offset plugin in the marketplace that can allow your first layer to be closer to or further away from the bed to help with first layer adhesion.
  10. Is there a way to have the top surface and the bottom surface have the concentric pattern while the rest of the layers of the top and bottom use the line pattern? What I'm thinking is that in some cases it would be nice to have the strength of the 90 deg alternating line pattern for most of the top and bottom, but for cosmetic reasons have the concentric pattern on the outermost skin layers. So far, playing with the settings I've only been able to have the following combinations. 1) All bottom and top layers lines. 2) All bottom and top layers concentric. 3) First bottom layer concentric, remaining bottom layers lines, top layers all lines. I have not been able to create first bottom layer concentric, remaining bottom layers lines, all but the final top layers lines, final top layer concentric. Also, what does the Top Surface Skin Layers setting do? I haven't seen it impact anything in the preview.
  11. Any reason there can’t be context appropriate links to the descriptions and images in the Ultimaker Print Settings web pages? https://support.ultimaker.com/hc/en-us/sections/360003548619-Print-settings
  12. I ended up increasing flow to 115% for the first layer after resuming and also leaving the cooling fan off for the first two layers after resuming. That seems to have fixed my adhesion issues with the TPU. Hopefully a moderator will still look at the layer issues discussed above with this extension.
  13. Thanks for the clarification on the flow setting. The design is actually from Thingiverse. It makes use of some lure making hardware that can be purchased and that is supposed to drop right into the cutouts. I agree with your comments, but I want to give that design a try since it wouldn’t require making my own wire structure. It does look weak, though, and like you I thought a solid wire connecting things would be better. I do hope a moderator will take a look at the discussion above and at the files I attached and provide some input on the behavior I’m seeing.
