  1. Well it’s with mixed feelings that I make this post. A 18 plus hour print just completed with no issues however, it was only able to be completed with the filament sensor turned off. IMO this makes perfectly clear that the calibration and or operational characteristics of the sensor to do work well with PVA. It remains my hope that the FW presently in beta has aggressively tackled this issue as it has plagued us since day one as well as many others. If not for the suggestion from “kmanstudios” to turn the sensor off I would still be hitting the resume button ..... over and over again throughout the printing process with there never being a valid issue with the PVA; phenomenal. As I said at the onset of this reply; mixed feelings because on one hand having the print completed without any intervention was wonderful and yet knowing that the sensor does not provide the solicited protection is troubling. Takes care.
  2. Good information shared Thank you
  3. Thank you; no caution is necessary as I like using PVA; in fact without it many prints could not be considered and yet I am a bit frustrated so all assistance is appreciated. Based on what you shared; the PVA that I use; both new and after being dried on the build plate is never truly dry. I have read many comments about PVA only wishing that I truly understood its characteristics. Some say it’s brittle when wet, others just the opposite. When I have had the PVA brittle to the point that a slight bend will cause it to snap then I have experienced it breaking in the Bowden tube when loading and I am unable to straighten it to insert it into the feeder. So using your comments as shared and my shared experiences how do you successful load and use PVA if it will break with only slight bending? Takes care
  4. I mean not to throw a random punch; and yet. Your issue is a great example of what the aluminum build plate was solicited to eliminate. Takes care
  5. Thank you for sharing your experience. I will step up that which I have been doing. To date I keep the filament in an air tight dry box. After a print I place the PVA in the original cardboard box and set it in the Ultimaker S5 on the build plate at 50c for a couple hours before bagging it with desiccant within the dry box. The printer operates in a controlled 65-70 degree F environment with relative humidity between 30-40% so as I understand; this is well below the PVA issue threshold. Giving up the sensor long term is not an option. I have read comments from others with the same issue and I understand that sensor calibration tweaks were made in the latest beta version; once it is released as stable I will try it and hopefully in concert with my actions good results will follow. Takes care.
  6. Thank you and no. The filament sensor has saved me on several long prints during which the filament gets bound on the roll; without it the time loss would have been a disaster. The filament sensor along with (dare I say) the aluminum build plate were the 2 significant reasons why the Ultimaker S5 was purchased. The current print is 18 plus hours and I have had to restart it no less than 4 times in the past 6 hours so I will test your theory. I just aborted the print, cleaned the build plate, disabled the filament sensor, and will now see how it does. BTW; I am not using the beta version. Your input is appreciated and I will refrain from sharing my thoughts until the print has completed. Thank you again.
  7. Any update to this issue? It has remained a pervasive issue with us, removing the filament and cutting a section off and reinserting it, aborting and restarting the print, reloaded the latest FW, cycled the machine, tried a new roll of filament, dried the filament per Ultimaker’s directions, etc. and the issue remains. It has become an impossible situation. BTW; always with PVA (maybe with the transparent too) so I lean towards a sensor calibration issue. Thank you
  8. Relax I update over the air and every time it begins the process and then seems to hang. I have to reboot the S5 and initiate the update a second time and then it works. I hope that you experience the same results. Please update this thread. Thank you
  9. First of all; thank you for the kind words as I know it is a bit of a double edged sword when I make some of my posts; the bottom line; I care. Now to your question; I too have printed much PLA without anything but a clean glass however, like you I too have been caught off guard when the occasional print lifts. As the result of this I prepare the glass “every time” thus insuring I have no adhesion related issues. It only requires a modest amount of time and glue stick and then spread it as I shared earlier to afford me “peace of mind” knowing hours later that I will be happy rather than frustrated. I wish for you only the best. Thank you again. Shadowman
  10. I can’t speak for others however, I use glue stick when needed and apply it to the glass and then I use a moist paper towel to evenly spread it around; no issues. Takes care
  11. Definitely not right; my S5 does not act as you’ve described. I don’t have the solution but rather the confirmation that you need one. Takes care
  12. Hi Smithy Your thoughts do not negate mine nor those of many others. I have had random adhesion issues and after understanding that the glass build plate has completely different properties on each side I am certain that I “now” understand why. Takes care
  13. I am with you RudydG As much as I appreciate the information; this should have be part of the original information as provided with the printer as well as with the replacement glass build plates. I have always been told by both the Ultimaker Support team and the distributors that both sides of the glass build plate are the same hence the ability to turn them over when chipped. In my opinion; this is another great example of value of the aluminum build plate. Takes care
  14. With all that you did; did you also reset the network settings within the printer? I hope that you find the fix quickly. Takes care
  15. It was great to read your reply; thank you.
