    Ah that's too bad. What material were you using? I wonder if carbon fiber nylon would work.

    Hmm I imagine that something could be printed to replace that metal piece so that the bowden tube would seal better. Do you think that would work?

    So how did you get the bowden tubes to fit into the feeder input side? The bowden tubes I have don't really go into that metal bracket. Did you print something to fix this?

    I had an all out blowout on my PVA on the print I did last night, the material was stuck, ground to basically nothing in the feeder. It took me 2 hours this morning to clean it all up. I did however just get my Polybox installed before my next print.. now I have a new PVA spool with some PLA in my poly box. Everything seems okay now except I am getting some issues with my fill on the PLA. Why are only some of the fill parts solid?

    Hi, I am trying to print a 200mm long rectangle that has been shelled out. The end is 24.5 by 2.75 with a wall thickness of 1mm. When i scale up 280% in cura it will show something to print. Are there some limits to wall thicknesses that cura can slice? I tried changing shell thickness to no avail. Edit figured out that I was exporting from Autodesk Inventor in cm when I should've been in mm.

    So I will totally get some the poly box. But I have a hard time believing that the filament could've gotten wet in 12 hours. I setup the machine the night before and then started my print 12 hours later. This was brand new ultimaker PVA. Also would moisture cause the burning? Or maybe there are some settings to adjust in cura?

    So I will probably just go ahead and buy either the poly box or the printdry system. Do I need both or just one? Also is one better than the other or should I just go with the cheaper material. I think I may have some humidity issues, but I don't think its that bad. I lowered the print temp to 218 from 220 to see if that helps the burning. So far it looks good.

    I have heard a pop, but the unit is probably 80 feet from my desk. The unit is brand new as is the material, so I would think that there shouldn't be much moisture. Should I try to heat the material up to ensure there is no moisture? Also would it be worth while to have a dehumidifier in the area? I have some weatherproof bins with desiccant in them to store the material, but nothing for the actual unit printing. I live in Louisiana so it is very humid down here on a daily basis.

    Hi, I just got my UM3 Extended and I did my first robot print and it turned out pretty good. This was after setting the nozzle switch position, manually leveling the base, then performing the auto level, and calibrating the xy. I am now printing my first actual print and I am getting stringing and burning with my PVA. What should I do to fix this? I used the standard fine settings @ .1mm layer height. I have read I need to look at retractions and right now the settings are as follows Retraction Distance: 6.5mm, Retraction Speed: 25mm/s Retraction Retract Speed: 25mm/s. These are all untouched. I am printing PLA with PVA supports. Please see the attached photos for the stringing. Is there a way to change just the second nozzle retraction? Or is there only one setting for both. Lastly the humidity in the building is around 42% and the temp is 72. Thanks in advance
