What this notebook is
Last updated: 2026-09-18
Three machines, one bench
LayerLog is a working notebook kept next to three printers: a self-sourced Voron 2.4 350, an Original Prusa MK4, and a Creality Ender-3 V3 KE. Every entry is a part that was actually sliced, actually printed, and then measured with calipers once it came off the plate.
The machines are deliberately mismatched. The Voron is fast, enclosed and fussy. The MK4 is the reference: when a spool behaves strangely it gets printed there first, because that machine has the longest uninterrupted history on this site. The Ender-3 V3 KE is open-frame and the least forgiving of the three, which is exactly why most of the tolerance and bed-mesh work here was done on it.
What an entry contains
A print log records one part: the material and spool, the nozzle and layer height, the print time, the slicer profile in full, a dimensional check against the nominal drawing, and the failure chain — the symptom that appeared, what was changed, and what the change produced.
A tune profile records one parameter sweep instead of one part: the values that were tried, the value that was chosen, and the reason the others were rejected. These are the entries that get linked to most, because a sweep is easier to reuse than a single part.
How it is written
Entries are drafted at the machine while the print runs and finished the same day, from the notes and the photos taken at the plate. Nothing here is a rewrite of someone else’s settings, and no entry is published before the part it describes came off the plate.
Where a print failed, the entry says so. A log that only records successes is not a log, it is an advertisement, and it would be useless to the person who reads it while standing in front of the same machine.
