  1. @GregValiant, your latest tool version works great. I examined the file contents, all is well.
  2. @obewan, I tried using the minimum fan speed. It helped somewhat. However, it doesn't solve the various cooling requirements for the overall model. It solved most of the problem. Now it fails above the raft. This is due to it is considered a skin thereby using the regular fan speed value and then increases fan speed gradually from there on up resulting in dropping for few layers. I'm going to give the above tool a go. Honestly, trying to resolve these types of issues with esoteric settings makes for many trials and is therefore very time consuming. When in fact a more direct approach, as in the tool above, makes for a greater understanding. Perhaps it too will be time consuming but educational.
  3. @GregValiant, very nice indeed. I'm assuming it uses Gcode comments to identify line types. Thats what is warranted for this type of finicky material. I'll give it a go.
  4. I increased the maximum/regular fan speed threshold from 25 to 50 seconds and looked at the cooling values in Gcode. Much better results, but not perfect. I'll try the minimum fan speed as well.
  5. I'm printing ABS in an enclosed 3D Printer. The attached models are the entire part and a segment of the entire part. The segment prints out very well. The entire part does not, see image. The issue is cooling and the print starts deforming around layer 50 and continues to ~ layer 75. Comparing Gcode results in a stark difference in cooling for those layers. The small part has 66% cooling whereas the full part has 15-30% cooling for those layers. ABS cooling must be used wisely, or the part will be brittle and or warp off the bed. Attached are the project files. Not sure this will be useful given the printer type is QIDI. So also attached is the GCode files & files containing the M106, M107, & Layer values in txt format, Duct Gcode.zip I think I need to dick around with cooling settings, see cooling image. Please suggest possible strategies to resolve this issue. What I would really like is a way to paint on cooling values for areas of a print that builds up too much heat. ABS may find this quite useful. Also, a way to see the fan speed in the slicer preview would also be useful. 1768022040_MonoDuctComposite-Body.stl Mono Duct Segment.stl 1727174379_XMAX_MonoDuctBodySegment.3mf 387699720_XMAX_MonoDuctComposite-Body.3mf Duct Gcode.zip
  6. I have a design that needs near solid material for about 10 out of the 50 layers. As an example, 5 walls starting tt layer 7 and ending at layer 16. Then back to 2 walls. Is there a way to accomplish this? I'm printing hundreds of these parts therefor this type of feature would save much time.
  7. I forgot that the helper line type was turned off. Ugh!
  8. Find attached the project file and image of slicing results image. I've selected support for everywhere and nothing is generated. I restarted Cura with a bridge test model. Same result. Then selected a different printer, same result. How did it get in this state and how can this be fixed? Tentacle.3mf
  9. Question, roughly speaking what is the minimum reliable 0.4mm nozzle flow rate? Keep in mind this is a low-end hobby 3D printer with all the upgrades and up to date marlin firmware. This includes better extruder gears and better spring to exert more pressure.
  10. I'm not sure my printer controller can handle Linear Advance. It is an 8bit board with limited memory. But something to look at. The next attempt at improving bridges will be trying to tune for less flow rate change. I noticed one bridge line, see image, is not controllable within bridge settings. Is this an oversight? The only way to tune this particular bridge line is using the Top/Bottom Print Speed. Seems like it ought to be added to bridge settings. Nor is there a setting to control the flow rate for that line in bridge settings.
  11. Thanks for your response... I just discovered, via a YouTube video, the Market Place "Settings Guide" plugin. It explains each setting verbosely. Interactions: Normal wall print speed and bridge wall speed. The greater the difference between them the harder it becomes to control filament flow. The same is true when adjusting bridge flow rates, the greater the difference between the preceding flow rate and bridge flow rate the harder it becomes for the extruder to succeed. It would seem reducing flow rate differences is a key factor. Therefor would it not make sense to compensate while approaching a bridge segment by slowing down thereby reducing the flow rate change. It looks like bridge coasting intends to do this. But why wait until one is about to bridge a gap. It would make more sense to gradually change both speed and flow rate before approaching a gap. Thereby keeping flow rate within extruder capability. If you have not already done so, consider adding the Market Place "Settings Guide" plugin.
  12. I'm trying to set the best bridge settings. Results are close to the images found in the ultamaker cura bridge article of bad versus expected. I'm working on a part cooling duct and bridges need good cooling. Material is PLA. Settings in the attached 3mf file. This is a monoprice printer with all the upgrades. Prints pretty well now. But, I noticed an odd thing on the first bridge layer. See image. The line starts out and has a very thin start then quickly thickens. I was wondering what settings to tinker with to improve this oddity. Thanks, Dana MU_Test - Bridge 2 Layers.3mf
  13. Solved, small feature settings override bridge settings. The small feature settings help to get first layer adhesion of small holes and features. Would it be better to have it not override bridge settings?
  14. The Project File: The previous file did not that the settings. This one does. Bridge Issue Project File.3mf
  15. I've tried before to get help with Ultimaker-Cura on this site and others. Hence the knock, knock, knock. Just to see if someone is paying attention. Now I know there are those paying attention. When questions go unanswered one has to assume either there may be no viable answer to the question or no one is actually active on the site. Again, the knock, knock, knock. I didn't realize there is a difference between save and save project. I thought I had saved a project file.
