  1. Yes, each one has a raspberry Pi and web cam plugged into it. It's a free for all, students just use the web page to browse thought the printer's cameras to find one that is free, then they send their print job to that printer. https://www.3dprinteros.com/store/easybox-cloud-3d-printer-management/ I goofed around with 3dprinterOS is NOT cheap and NOT opensource, and does not really deliver on the accounting side which was most interesting to me as an educator who needs to keep track of who's printing what and accounting quotas. I have not found anything that does that.
  2. thanks! I just noticed on the file I thought was good that the nozzle did turn off before the motion was done, but it did not matter since the last several moves only took a ~2 seconds. Cura 2.3.1 is putting that M104 command in the gcode. I did comment that out and things are working better. I like the idea of the M400 suggestion, this would come in handy in a lot of other contexts too. FYI - Changing my CURA version is a HUGE undertaking that I fear going through.
  3. Only some files on my UM2+ are turning off my nozzle (like a M104 S0) before the print is done. It's like the firmware is using some look-ahead and executing the "M104 S0" immediately before all the buffered "G" movements are done. So what happens is the nozzle temp drops resulting in grinding and under extrusion. So far I am only noticing it on very simple files (only about 120 lines total) AND ONLY if a second layer and fan are needed. (FYI-warning these files are for a 2.0mm nozzle , so if you try to print with a smaller nozzle you will have trouble - in cura line_width=2
  4. Fingers crossed. I'm looking forward to a new font! and leaving bugs and frustrations behind. Even if I lose all my old posts, and go back to "level 1" I think this is a good move.
  5. @sandervg this is great news. I am so happy for us. I also agree with @lepaul that "ease of use, quick load time, pleasing to the eyes to view content and so on" should be factored into the reboot. This site forum (and the UM site) is horrible on so many levels. I am so happy about this news. Is it too much to hope that you will be ditching this font too.
  6. We do a lot with openSCAD at the lower grade levels. It's free, cross platform, reinforces mathematics and computer coding, and has a easy learning curve if you're only doing basic stuff yet is very deep if you want to do fancy things. With the really small kids we keep them in 2D art programs as an intro. see this write up Once the kids get older (13yrs+) then we can introduce things like tinkercad (due to legal reasons). The High school kids use a lot of different tools: meshmixer, tinkercad, (looking for a replacement for 123D Catch - but that was great while it lasted), autodesk, blend
  7. Here's a photo after I scraped at the flakes with my finger nail and spread some down the side.
  8. This is really strange. I am getting what looks like an accumulation of tiny metal flakes only at the tip of my atomic method pulls. I've already done about 7 pulls and each time I am seeing this. I am not seeing any metal flakes or dust anywhere else in the path (extruder teeth, bowen tube, etc). The outside of my nozzle looks fine, before the pull the filament looks like it's coming out really nice and cylindrical, after the pull when I look down inside the nozzle I see shinny clean looking inside of my nozzle. BUT when I look at the pull I get these strange flakes only on the tip (see photo
  9. I think you are correct about adding the raft height. This plugin has always been kinda buggy for me. I use it a lot, you have to put in the exact Z height and it's best to account for slicer rounding. for example...if you have 1st layer=0.3mm and are slicing at 0.2mm you will never have a layer at 20mm, you will have a layer at 19.9mm and a layer at 20.1mm. The plugin has to choose where to do the pause. ALSO - it always breaks horribly if you try to do more that one pause in the print. This has always been an issue. I just jams all the pauses into the same space, ignoreing any height inf
  10. for "one at a time" I use cura 15.X I think cura 2.3 and 2.4 are broken for "one at a time". for one thing I think they ignore the print head size, and I get items crashing into the print head. https://ultimaker.com/en/community/39281-cura-not-using-user-set-machine-print-head-size
  11. So far looks like the solution was: 1. Do a third "clean install" - not sure why the first 2 did not work. 2. The old printer it was pulling in had a printing profile associated with it that contained a comma in the name, which breaks cura 2.3 and that is why the machine failed to load almost every time. Thanks @ahoeben for seeing the printing profile issue in the logs!
  12. Oh, good eyes. I did not know that was not a character that was allowed. I will keep this in mind when making new machine profiles. Are you aware of any other characters I should avoid? Like slash / or period . Or colon : I could see if this becomes the file name those might cause issues.
  13. UPDATE- I repeated the "clean install" process one more time. --------clean install as I currently understand it--------------------- 1. uninstall all previous versions of cura 2.x using the uninstall.exe file in the C:\Program Files\Cura 2.x folder 2. delete (or rename/remove) this folder *username* \AppData\Local\cura 3. Install the new version. ------------------ AND I'm on my second day of cura remembering the printers, even after reboots. Hopefully the 3rd time is the charm and what ever was wrong with the installation is now fixed

  15. No I have not. I have only added printers through the normal front end interface.
