Suddenly Ryno will not adhere to the bed
-
Bought the Pulse XE, it worked perfectly with Ryno PETG right out of the box. Then I changed to nylonX for 2 small parts. When I went back to Ryno, it would not adhere to the bed. I tried temp. variations, glue variations, nozzle distance variations and finally thought of drying the filament, baking 7 hours at ~170f.
Nothing, zilch! Was the nozzle damaged by the nylonX? The filament flows out properly.
Help!
-
@gonzer What kind of nozzle did you use to print the NylonX with?
-
Stock nozzle that came with the PulseXe package. The total weight of the nylonX parts was 8.2 gm, surely not enough to affect the nozzle.
(Garolite heated bed btw)
-
@gonzer If it is a brass nozzle, then yes, you need to replace it. Consider buying a hardened nozzle. If you are printing on Garolite, you can try sanding the surface. I use 80 grit paper and then I wash the bed with soap and water. Are you printing inside an enclosure or open air?
-
The hard steel nozzle. Interesting idea, sanding the Garolite. I did build an enclosure for retaining the warmth. What about raising the bed temp much higher to initiate the adhesion?
The mystery is why the complete failure of adhesion merely by changing filament from nylonX back to Ryno. The control settings all seem correct.
-
@gonzer Did you change any settings in MC? Did you change the filament type? Like first layer size? PETG prings best on pei sheets. Someone from my group suggested to raise the temperature to 250 to get it to adhere to the surface.
-
I will try the suggestions next go around and report results. Thank you
-
@gonzer hit it with the good ol glue stick is what I did
-
@gonzer I find that printing with the bed hot (75c-85c) ensures that the filament contours into the build surface, specifically the PEI, and I also disable the part cooling fan for the first 3-5 layers
