  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,...

  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. Alright, I've upgrade to the latest firmware. So far so good as I didn't have to walk down to authorize Cura. I did start a job, so I'll have to wait until it finishes before I can see the settings, but I recon it's ok. Thanks!! let's hope 3.6 behaves as it should.
  14. Yes there is actually. You assume that any new firmware is an improvement of the old. I actually downgraded a couple of months ago to this firmware. I had it for months, it worked flawlessly. Then it successor promissed some nice feature. Ok it was kinda nice to be able to switch the light off. (At night my office always looks like there is some alien spaceship landing going on) but the new firmware brought nothing but shitty wifi reception, every time I had to walk downstairs and the USB support was crap too. Unplugging and reinserting did not refresh the filelist on it anymore. So basical
  15. Hi, I've just experienced one of the weird things. Last time I changed filament, I thought I was too quick and just fat fingered into the wrong type. Occasionally I twist and press, not just press. So I put on an ABS spool but hit PLA,. I thought. So after it loaded, I thought, I'll reload it. Because otherwise Cura keeps questioning me. Then it hit me: I've lost ABS, actually the only types left are PLA, CPE and Nylon,.. Also change type under material 1 does not show all types anymore. Only the above 3. I restarted the printer (power off) but to no succes. It is only those 3. I h
  16. Wenn es nur um die Eckenhaftung geht sehe ich da kein Problem. Einfach den Klebestift nehmen, das läßt sich jederzeit wieder gut entfernen. Not exactly, the dump for extruder 1 is better than the one for extruder 2. Have a close look, they are not exactly the same. Extruder 1: move to 2mm, start extruding, move up slowly then move away a centrimeter and lower. Extruder 2: move to 2mm, start extruding, move up (too slowly), move away and stop extruding. Then move back to dump location, dip lower and up and move away. The moving up too slowly and the return and dip cause the pile
  17. I have seen the same problem. Like you: nothing is done with the 2nd extruder. All things buildplate adhesion supports model etc. Only extruder 1, yet somehow Cura thinks the purge is necessary. I have even had prints where the 2nd extruder gets heated up to 100 degrees standby temp for no usuage. Simplify3D had a tendency to do the same untill I edited the startup script and removed the purge. I guess you could do the same. A bit of googling should get you the change extruder and purge commands. Remove them from the gcode and it should be fine. Still, I agree with you: why would i
  18. Haven't tested this 100% but if you list the files to print, remove the USB and reinsert it. It does seem to refresh the file list. That would get you beyond having to reboot the printer. Need to see if listting the contents still works after you fininshed a print (from the USB). If it doesnt, then you are just sh*t out of luck :-(
  19. Similar behavior here, my iPhone seems to always want to connect regardless which firmware, but the previous version at least would connect Cura again (after I had to run down and approve the access request). With v3.6 there is no popup on the server to approve and there is just no way to connect it again without having to restart the printer. I'm not a bit fan of continuesly flipping the on/off switch and I found that if you switch on/off developer mode in the maintenance menu, it reboots the server. Probably better on the hardware than the on/off switch.
  20. Exactly the same problem, my previous firmware would notice the USB got inserted. If I would insert and go too quickly to print, it would be empty and then populate with the files on the drive. V3.6 only gets me the go back option, no file/usb notification occuring to refresh the contents.
  21. 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
  22. Yikes I'm not entirely sure if I'm comfortable loosening screws on a 5 days old machine. Way too many things I could screw up. I got a exchange in 14 days policy on the machine, I rather think they techie in the shop can sort that out and just get me one which is sorted. After 3 years doing that, I'm fine (or if it had only costed like 1% of the current price) :-) Thanks!
  23. 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
  24. I'm going to give it a try tomorrow. I tried it before, tightening the screws almost completely. When i did that, I did an manual level and after that an auto level, the bed didn't even come close to the nozzles. I see if I can slowly untighten the screws so it comes higher. Hope this will work. Thanks!
  25. 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
