  1. Really cool tool -Thanks for sharing. I didn't see any extrusion issues in the gcode, but it must be there somewhere. I am printing right now with 0.8mm nozzles flawlessly, so something about the 0.4mm nozzle config/profile must be screwed up. Are there and global core/nozzle settings somewhere in cura?
  2. GR5, thank you for the thorough response. I'm pretty confident it is a software or slicing issues as my colleague isn't having issues printing from his computer. That being said, I have done the following to address what you've described above: I did confirm the fan is spinning using the method described. I tried two brand new print cores, and cleaned the contacts on the carriage and the print core. The feeders are pulling strong, after taking them apart they had very little debris (we clean them regularly). Fortunately, no filament manager, so I don't have to worry about that. After checking printer logging, I am pretty much certain the temperatures are good to go, unless I have used several cores in a row which have bad thermocouples. I am going to run both printers with the exact same setup and view the web interface data logging. My suspicion now is that the feeders are not rotating as fast as they should. I'll let you know what I find.
  3. Okay, I have just done a fresh install of Cura and reset both printers. Both are running the exact same nozzle and filament setup, regular ultimaker pla, and AA 0.4 nozzles. The problem persists on one, and is absent on the other. I monitored the printer in web interface during the print. Everything was correct as far as I could tell. I chose to DOUBLE the flow, and half the print speed. It is extruding closer to the correct amount of material. What would cause such gross under extrusion on factory settings? So weird to me. No extruder slip or any mechanical issues.
  4. Hi All. I am fortunate enough to have two ultimaker s5's at work with air managers. For a time, they both printed great, now, one of the two exhibits severe under extrusion on walls and infill (ie not on roof, floor, or brim). I have ruled out any mechanical issues, swapped both print heads, verified the filament drivers are functioning properly, etc. Both printers are running the latest stable firmware, and I have confirmed they have the exact same configuration in cura. I've reinstalled cura several times. My colleague doesn't have the same issue, I'd like to think I have considerable experience with printers, but this is testing me a little bit/ I don't have the time to fuss around with it. I've played around with the slicing settings but nothing seems to fix it. We have had an intermittent issue with this printer maintaining temp during endurance prints, but it is not consistent enough to diagnose or say it is related to this issue. Any suggestion are welcome. -WB
