Beta. Read this before you printThis is experimental. A disc takes one to three hours to print. Stay near the printer, especially for the first layer. The record is soft PLA: play it on a cheap cartridge, never on an expensive one. You print and play at your own risk.
Vinyl·Engine
Turn an audio file into a playable vinyl record you can print on an ordinary 3D printer. No 0.2 mm nozzle, no resin. A 0.4 mm nozzle and PLA.

Where do I get this file
In Bambu Studio slice any small object (a 10 mm cube) with your own profile: P1S, 0.4 mm nozzle, PLA, 0.2 mm layers. Then Export → Export plate sliced file. We only take your printer's start and end G-code from it. The engine writes everything in between.
02What to press

Printer profile first (step 01).
05Tune it to your turntableoptional, but it is the only way to better sound
Print the tuning record (step 02), play it at the same speed and record it over USB. In Audacity start recording before you drop the needle. Upload the recording here. The engine measures how much of each of the eight tones reached the amplifier, separately at the rim and in the centre, and computes the correction every later record gets.
Generate a tuning record first. I need its layout to match the recording.
