This is the first time I’ve seen this happen not sure but it looks to be under and over extruding could this be the cause of bridge flow? Where the disconnect starts is where the bridge begins then it’s a mess after that. Any help would be appreciated.
Printer: P1S
Nozzle: .6mm
Filament: Atomic PETG
flow calibration, volumetric speed have been done.
If I’m forgetting something feel free to let me
Know.
Observing the photos, it seems to be delamination at that height.
Your bottom layer cooled down and didn’t bind to the top one.
I cannot specify the reason, but I would guess it was an odd event or wrong print settings.
Did you have any event during the print? e.g. filament spool stuck, change to another spool, etc…
If not, check the sliced file in the preview section (layer time, layer height (if variable), speed, flow, fan speed, …) for any significant difference in that region (i.e. distinct colours).
No event that I noticed but I will be checking the sections and see what the difference is, I could try turning off the Aux fan and lowering the part fan a bit to let the layers cool down slower. thanks for the input friend!
That is a valid option, as well as increasing the print temperature, slowing down,…
But before moving to tweak solutions, I would try to understand the cause to avoid loose time. Besides the slicer, just check if the hotend is in good condition.
checked all the mechanical components and they seem to be in clean condition, I didn’t get a chance to get the test done but I will do that today and will be back with more info. hopefully, if someone else runs into this it’ll be a good guideline. Thank you for the help!
