  1. Lake monsters. My flying boat was eaten by one. I was flying close to the surface minding my own business and suddenly the lake sprang up and ate the airplane right there in front of me. Water can be really hard when you smack it.
  2. Hi. The strong centre line and its branches are on the print. Not sure why, the don't line up with internal structure. The very faint lines are the ones I am curious about. They seem to be very wood grainish. Look like the surface of a plywood sheet. This certainly may be due to adaptive features at work. I will try a print with that turned off and see what happens. Planting model airplanes in trees is a time honoured tradition. That is why I always have a chain saw handy. I must admit that the more time I spend on Real Flight 8.0 on the computer, the fewer trees are endangered. W
  3. This is a purchased set of plans from Eclipson and they ask that their files not be posted or shared anywhere so I will respect that. Adaptive Layers is turned on in the profile. Do you recommend that I turn that off? Eclipson recommends three profiles for their models, A, B, and C. Their plans specify the Cura settings for each profile, and show which parts are printed with which profile. I modified the Cura Dynamic profile for each one. The prints use no infill and no supports, just thin skins and internal structure to make them as light as possible.
  4. I am curious about marking on my prints that resemble tree rings. This is on thin wall prints for an RC airplane in Cura 4.8. The files print well but all of them have faint markings that are not on the files. I haven't see this before. The photo shows the markings ( the faint ones, the stronger lines are on the print file). They are faint so you will have to enlarge the photo to see them. I have never paid much attention to the patterns on the models in Cura in the preview screen. There are all kinds of surface markings in the preview screen look like moire patterns. Is it possible that some
  5. Well Duh. Yes it was set to brim. I set to none and it fits. Thanks a bunch. Completely missed that little detail when I reviewed the profile settings.
  6. I have run into the problem of trying to print large items that are close but not quite the full size of my build plate. My build area is 220mmX220mm. The model I am trying to print is circular and shows as 210mmX210mm in Cura. However Cura shows the model greyed out and will not slice it. Playing with the scaling function in Cura I can print it at 200mmX200mm but not 205mmX205mm. It will print at 203mmX203mm but not above that. So Cura is leaving 17mm on each side of the model as a reserve that is non-printable space. This seems excessive. I should be able to print my model full size at 210
  7. This "Wait for User" issue is driving be crazy. My printer is a Crealty CR20 using Cura 4.4.1 running under Windows 10 ver 1809 64 bit. This printer works well and has done hundreds of prints. I am trying to make a rotating tool holder. This is the biggest print I have ever done on this printer. It fills the build plate. The tool holder is in 3 parts. The top is full of holes and features and it printed perfectly. The base is solid, and the long print lines seem to have brought out this error. Every few minutes the printer stops with "Wait for User" showing in the printer's LED panel. Push
  8. Hi. I have the same problem with a Crealty CR20. It has a 220mm square build surface. For the first time on a large print I noticed that it is printing really close to the front edge. When I Autohome the print head the nozzle is about 4 mm forward of the build plate. The problem is the rear limit switch. It allows the build plate to move too far backwards when you do an Autohome. Manually moving the build plate forward to where I want it leaves the rear stop about 5mm forward of the limit switch. I loosened the mounting bolts on the limit switch to see if it would slide forward but it is no
  9. For the first time in a year of using Cura with a Crealty CR20 I am getting "Wait for User" errors during printing. The print head stops and waits for me to push the button on the printer and then starts again. It does this every few minutes. There are many threads about this on the forum. Lots of suggestions and theories. One that caught my eye is the observation that this problem seems to emerge when there are long straight print lines in the model. I am making a rotating tool organizer. It is the largest object I have ever printed on this printer. The top has lots of holes in it so no lo
  10. Thanks a bunch for this info. I will keep it handy in case I need it. So far 4.4.1 is behaving itself but if I do end up needing help I will start a new thread and post the log file.
  11. Hi. After a trouble-free year with several versions of Cura my 4.2 version crashed. I got it going again and it crashed again. I read this topic and searched for the log files where they are said to be on the Github link above. You are supposed to be able to access them in the Cura interface under Help - Show Settings ( no such menu item ), or create them using start-run-dxdiag-save output ( no such function running dxdiag ), or find them in Appdata\Cura\(Cura Version)\Cura.log ( no such entry ). I searched the whole computer for Cura.log with no result. I am using Windows 10. I think all
  12. Hi. I am a new user and have Cura 4.2 running well, waiting for ver 4.4 to be released. I am printing small parts currently with a .4mm nozzle. They turn out well but in the interests of getting the most detail possible I would like to try a .2mm nozzle. I am using a .1mm line height and a 2 wall thickness in Cura. With a .2mm nozzle would I be able to use a .05 mm line height and 4 walls? Does the nozzle size have any relation to the line height? Can I use smaller line heights with smaller nozzle sizes or is there no relationship there? Is a 0.5 mm line height too much to shoot for? I wo
  13. Well that is amazing. Ok, understand now. My mental state is fixated on larger projects. Doing teeny tiny stuff would certainly require smaller nozzles.
  14. So what does decreasing the nozzle size do? If I change from .4mm to .25mm nozzle the print line width will be narrower but the line height will still be the same as that entered in Cura. I would need more passes to get the same wall thickness using the .25mm nozzle. This would make the print take longer. So what is the advantage of using a smaller nozzle? In what circumstances would you want to use a smaller nozzle?
  15. I may have answered my own question. The top part can stand on its own after I detached it from the main body. There is enough angel hair extruded below the top portion to support it. The first parts of the top piece are pretty rough but the top edge itself is fine. Interesting observation on support. It didn't take much to allow the printer to actually print the top piece. Maybe less support structure would work fine in some cases.
