  1. Yes, that's probably the way,.. 😞 Not the easiest way though, I will try if the .gz might be it. That would be a quick fix. Just out curiosity, did you try any of files. Just wondering if it is firmware related. Hope I can just downgrade to something old and get this to work. The darn machine should just open gcode without me having the edit a file,... I'll try to dump the logs too, that's a good idea, maybe I can see it bail out for some reason, although again, that is in the printer firmware as these file did print previously from USB on
  2. I cannot find the edit button of the post, so here are the files,.... There is one which will print from USB, the others just don't, neither can you send them to the cura connect queue via Cura. If anyone can shed some light on this, much appreciated as it is darn annoying not able to print with an UM3 and a USB stick with generated models,... Cheers, Richard Velg - original - v3.gcode Bottom Pad-v3-1x-0.4-L.gcode flat hoekstuk - v4.gcode Raincap-v2.gcode
  3. Hi, I think I stuck some kind of bug in loading gcode and printing from USB. When I try to print from USB and the gcode is generated by Simplify3D, the screen shows the name on the screen. It cannot show any details (just shows ‘loading’. When I select it to print. The screen jumps back to main and then back to the usb file view. And that is it. When I select a cura generated (compressed) gcode gz file, it starts to print. When I select an old gcode file which I am sure I printed in the past, same is happening, it does not work. Is this a bug introduce
  4. And I switched active levelling back on 🙂
  5. Hi, Now that was what I was looking for! Thanks for pointing it out! 🙂 Cheers, Richard
  6. Hi Johnse, Thank you for the answer, I assumed a similar thing that it does some Z-axis adjustment, but what specifically wonders me how it would deal with the 3 point measurement. On my UM3 you do the manual levelling mid point, right front, left front and the dual nozzle midpoint by adjusting the screws underneath. This should put the build plate level. Assuming I messed this up and right forward is way too low. How would my UM3 auto-levelling deal with that? It cannot adjust the right forward screw to make the plate level, so the only thing it can do is
  7. I only occasionally read through posts on the board here and saw a big discussion on auto-levelling which made my curious on what auto-levelling actually does. Does auto-levelling actually adjust any setting/layer height or print condition or is it only a safety check to see if the build plate isn't complete mounted sideways? Just curious to know the inner workings,..
  8. Hi, I'm wondering if other people have some experience with this. I have an UM3 extended and print 99.9% of my things sliced by Cura (4.2.1 at the moment) I do some CAD drawing and pretty much always, my printed parts never fit. Despite my putting some margins in the drawings, I usually end up doing print-try-adjust-drawing and start all over again. Since for me this is all hobby and I have by no means any knowledge or experience how you should take fitting tolerences into account, I figured it is the best I can do. But recently it just annoyed the heck out
  9. I’m trying now to increase the bottom top layer width to 0.45 from 0.35. Lets see if that makes a difference.
  10. Hi, I'm looking for some pointers as what to check/adjust to get this issue resolved on my prints. These prints are done in PLA, but aren't material specific. Cura versions: this happens with 3.5.0 and the previous 3.4.1. I don't think it's Cura version specific, I've had this issue for a while. This is printed at the default 'fine' setting of 0.1mm and a modified fine setting where initial layer height was decreased and print speed reduced to 35mm/s When I print, the bottom/100% infill layers seem to be dimensionally smaller than the layers hi
  11. Alright, so I rebooted the Ext, rebooted the wifi, just went to maintenance and ran the setup from there and it worked. Very puzzled but pleased it is now working.
  12. Hi, I'm looking to getting a few pointers here. I've had a UM3 for over a year now and just unpacked a brand new UM3 Ext. It's now standing where the UM3 stood. The problem I'm facing is that I cannot get the Ext to connect to my wireless. When attempting to connect (after the wizard of wife network and password filled in) it times out after a number of minutes. I had no issues with connecting my UM3. Anything I can try or check? I just rolled out a cable and upgraded to the latest stable firmware on the Ext. The UM3 was already o
  13. Hi foehnsturm, You started your post with that you finally got your PVA to stick. What is the trick to that? Ever since the beginning on my UM3 I'm having the problem with getting it to stick to the buildplate. I've tried the Uhu glue stick, 3D lack (sort of hairspray), making the water disolved PVA mixture, printing slower and slower. The one thing I need to double check is the bed levelling, I kind thought it was a bit on the high side which could make the adhesion problematic. What also strikes me as odd is the priming of the PVA extruder at the start. For the non PVA prints coming from
  14. Yes, I had that too, the second time it is succesful, even without any wiping or so. But the problem is with when it automatically decides to auto level. I cannot use that feature as it basically means at a certain point the printer will auto level, fail and I have to go down to flights of step to acknoledge with a press on the front button. Better to completely disable the auto leveling then. I got a pointer to this message, will give that a try, even though I've been there and almost completely tightened the screws and tried. Maybe I tightened them too much. https://ultimaker.com/en/com
  15. Hi Wisar, Is the auto leveling now always working for you? I just has my printer 4 days. Did a firmware upgrade on the setup. I'm on version. I set it up to auto level before each print (really it takes a couple of minutes, less than 1% on some of my 18 hours prints) but it just keeps failing on the first auto level, every time. It was so bad that I basically cannot sent a job over the network, as the printer would fail the leveling and the job would be completed without printing. So I just disabled it for now. I manually leveled the bed at least 10 times now. I tried wit
