Attention over time

7-day rolling share of analyzed posts/comments mentioning this entity · 90 daily points ending 2026-09-01

Final complete day: 2026-09-01. Attention was 0.1% — this entity appeared in 21 of 17,943 analyzed posts/comments in the seven days ending that day (21 mentions).

Each point is a seven-day rolling window of complete UTC days; a point is comparable only when at least 100 analyzed posts or comments fall inside it. A day with no analyzed records counts as zero; missing coverage is marked and never shown as zero. The series ends at the latest complete analyzed day — it never extends into the current incomplete day. How attention is measured.

   The waviness is a sign that the Z-offset is too low. !firstlayer - adhesion and warping With PLA, a clean smooth surface is best. PEI or PEX is great. You may have to raise the bed temperature on a textured sheet. Silk PLA may need a higher initial bed temperature. PETG, TPU, ABS, and others will need a release agent on a smooth build surface. That's what the glue stick (or hair spray, Windex^^® ) is for. On a textured sheet, no release agent is normally needed. Just alcohol will not remove the sugar film left by PLA which can hinder adhesion. Wash the sheet with warm water and dish soap. Dry. Wipe with > 70% Isopropyl alcohol before the print. No part cooling fan for 3 layers. Very slow print speed for the first layer. To prevent warping for PLA, bed temperature of 65° for the first layer, 55° for the rest of the print. This way the bottom gets the adhesion but the bottom starts cooling with the upper layers. For PETG on textured bed, same concept, usually around 80° then 75°, or 75° then 70°. Temperatures are examples, different build sheets may need different temperatures. Infill style can affect warping. Some grid type infills can concentrate the stress in one area. Gyroid infill will spread out the internal stresses. Increasing walls number and reducing infill may also help.

   Pillowing. Add number of top layers and increase infill percentage. The hinge - "Minimum Layer Time" must be increased.
