I have an update.
I upgraded my thermistor and firmware (TH3D) and tried a NylonG print again. I let it sit on the plate over night (like intj123 suggested ) and it produced a structurally strong print.

@michaelchien NylonG is more impact resistant. I would use that.

@thwclw I'll try increasing the temperature. My thermistor is stock - soI ordered Slice engineering PT1000 RTD for my nozzle. It is spec'd to 300 C . I'll let you know how it works out.

I'm using a a MK8 harden steel nozzle from micro swiss. It is holding up so far.

I may have to wait until winter to figure out if it is the humidity.

Hello,

I am trying to tune in NylonG on an Ender 5 Plus w/ a microswiss hot end. I am getting great looking Bechy_3d's. They have minimal stringing and very visible details. However, they are structurally weak. The sides of the hull can be easily torn off, along with the cabin roof.

I am using a sunlu dryer at 55 deg C overnight and spooling the filament directly from the enclosure to the printer. There are no adhesion problems.

I am printing at255C, bed temp is 65 C.

Any sugeestions?
