  It was under 50% relative humidity in my garage today, so I just put the spool right on the printer and hit “go” :)

  Over 50% and I usually run active filament from a dry box to the printer

  I haven’t gone to the trouble of pre-drying a spool yet

  According to the print visualisation, there is no cooling at all on the top layer, only on the 3rd-from-the-top layer, which is right above the last sparse infill layer (I have top shell thickness set to 3 layers)

• ⁨Comment⁩ on ⁨delamination on larger surfaces⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  okay, just viewing the job layer by layer, i can see that the first solid infill layer after the sparse infill is treated as an overhang/bridge and triggers 100% cooling fan (otherwise it’s at 0% for the rest of the print)

  and i on some items, i can see where the delamination on this layer caused problems on the next couple of layers on top

  but, on other items, there’s still delamination happening on the very top layer even without any issues beneath it

  for this 230C - 250C PETG filament, i’m already at 250C (but i’ve been contemplating bumping it up to 255C)

  No, it’s an open bed slinger I think my next printer will be something enclosed

  • Sovol3D SV06 ACE
  • OrcaSlicer recently gained a built-in profile for exactly this model, and I’ve had all sorts of issues since switching to that profile (previously I started with a generic printer profile)
  • the new profile is fine on PLA, but PETG is what I’m currently using
  • yeah, I only just learnt about the print visualisation feature, the delamination does seem to frequent the same place on the object/plate
  • it’s the 6x6 panel from www.printables.com/model/859807-print6-panels
  • the spans from cross hole to cross hole are short and never delaminate
  • the long straight edge-to-edge spans that dodge the holes have been troublesome
  • the plan is to reduce acceleration a bit more, and then (if that doesn’t help) reduce speed a bit (I’ve already reduced speed and filament volume anyway because of PETG)

• top-layer delamination solved by lower speed
