  1. 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.
  2. 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 210mmX210mm. A 10mm reserve is surely enough. I have checked my printer settings in Cura and the build surface is set to 220mmX220mm. I don't see anything in the settings that allows me to set a smaller unprintable space on the outside edges. Is there any way to do this?
  3. 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. Pushing the control knob starts the printer again. However a few minutes later it stops again, and again I have to push the control knob on the printer again to start the print. This continues throughout the print. It is impossible to live with, I can't leave the printer for more than a few minutes, and this is a long print job. I have read about this issue emerging with long print lines in a model. I tried lines and zigzag in the Cura profile for bottom layers and first layer. No change. This is a very frustrating issue. I have included a picture of the top part with holes ( no problem printing this ) and the bottom part that is solid and causing this "Wait for User" error. The log file is included as well. See the date 2020-02-24 for the log associated with the problem print. I really hope this can be resolved, and also really appreciate any help you can give me. cura.log
  4. 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 not adjustable. So my only solution is to move my build surface as far foward as possible using the paper clips. This is only a problem for large prints that are close to the size of the build plate. Most of my prints are smaller. I have a question about this in to my vendor but no response yet.
  5. 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 long lines. It printed perfectly. The base however is solid and has very long print lines and this is the situation in which I am getting the wait for user error. So if it is long print lines causing this, the obvious solution is to make them shorter. Either create interruptions in the geometry of the base, or use a base line pattern that is not straight. Cura offers Top/bottom Pattern and Bottom Pattern Initial Layer as lines, concentric and zigzag. It is set to lines in these prints. When I try concentric and zig zag as selections in Cura and slice the model there does not seem to be any difference shown in the Preview window of the print from that with lines. The print times all stay the same. Concentric offers a line in which you can enter numbers for polygons, and zig zag has that line for entering integers. I don't know how to use those features or what they do. So would Concentric or Zigzag create shorter line lengths in the base of the print? Which one would be the best to use? Or should I just add a few holes in the base to interrupt the long print lines?
  6. 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.
  7. 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 these references are out of date. I gave up and upgraded my Cura 4.2 to 4.4.1. So far things are running nicely. But just in case, where do I find the log files for Cura 4.4.1 running under Windows 10 (64 bit version)?
  8. 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 wonder about the smaller nozzles plugging easier. Thanks Don
  9. Well that is amazing. Ok, understand now. My mental state is fixated on larger projects. Doing teeny tiny stuff would certainly require smaller nozzles.
  10. 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?
  11. 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.
  12. Just looking at the photos now I am curious as to how the printer managed to print the top section of the enclosure at all. The whole thing is hanging out in space with no supports. But the top is mostly there. What would have held up the first layers that were printed out in the open air?
  13. I have printed an enclosure for an Arduino Uno successfully but had to make changes to the access holes for the USB and 12v connectors. The second print was coming along nicely but when I checked it this morning there was a surprise waiting for me. The top part of the enclosure was offset from the bottom. I cudgeled my brain for reasons. Did Cura reboot the printer for some reason? Did my cad file contain a fatal flaw? Did the printer head or the bed skip on the drive belt? As I mulled it all over my wife reminded me that the clocks were flashing this morning. We live in the country and small power outages are common. So the power went down, the laptop didn't care but when the power came on again the printer started but must have lost its reference to home. I'm impressed that the printer tried to keep going. I wonder if given our power situation a hefty computer UPS battery for the printer would work. Most power outages here are short.
  14. Wow sorry to hear that. I have a Crealty CR-20 and as I described it works great via USB. I started printing with CR-10 selected as my printer in Cura since that was all the 3.x versions listed. Version 4.2.1 has a lot more printers listed including the CR-20. Trying to think of problems that popped up. One thing, when I first did the upgrade to ver 4.2.1 And selected the CR-20 as my printer Cura started giving me errors saying my CR-10 configuration files were corrupt. I could no longer contact the printer. Cura wanted me to do a reset that would delete all the printers and profiles. I backed up my profiles and did the reset. Then reinstalled the profiles and selected the CR-20 as my printer. All worked well after that. Windows 10 was hassling me to update my version of Windows since the current version I was using would no longer be supported after November. I hate upgrading Windows but on a dark and stormy night the laptop just went ahead and did the upgrade all by itself. I had to run the install for those drivers again. The rebooting sounds like it could be a connection problem. Could it possibly be the USB version you are using? USB has three versions now. What help is your vendor offering you? You could call Mech Solutions in Toronto and talk to Sim. He is very knowledgable and got me up and running when the card reader broke in my CR-20.
  15. I didn't back anything up before installing these drivers. It is a very simple install. It doesn't matter if you are using a laptop or a desktop computer as long as it is a WIndows machine. Won't work with a Mac.
