Printer profiles and settings
The printer profile is how OpenChip knows what your machine can make. Every manufacturability warning is measured against it.
First run
Section titled “First run”The onboarding wizard asks for it before anything else. Pick the closest preset — Standard 4K resin printer if you are unsure — and name the project.
Three presets ship, with their headline numbers:
| Preset | XY resolution | Minimum feature | Build volume |
|---|---|---|---|
| Standard 4K resin printer | 35 µm | 0.2 mm | 143 × 89 × 175 mm |
| High-resolution 8K / 12K | 20 µm | 0.12 mm | 219 × 123 × 260 mm |
| Large-format resin printer | 46 µm | 0.25 mm | 298 × 165 × 300 mm |
There is also an enter my own path, seeded from the standard preset so you are correcting four plausible numbers rather than filling four empty boxes.
Every field is what it says and every field stays editable. Field-by-field detail is on Printer profile fields.
Changing it later
Section titled “Changing it later”Settings → Printer. The profile you set there becomes the default applied to every new project.
An open project carries its own copy — a .openchip file stores the profile it
was designed against, so a chip someone sends you arrives with the assumptions it
was built under. Change the open project’s profile from the CAD panel; change the
default for future projects from Settings.
Changing either re-runs every check immediately. Nothing about your design changes, only what the app says about it.
When to change it
Section titled “When to change it”- You changed resin. Cure-through and minimum feature both move. This is the most common reason a chip that printed fine last month does not now.
- You changed machine.
- You measured your real limit with a test coupon. Replace the rule-of-thumb
minFeatureSizeMmwith what you actually measured. See A first test-print protocol.
The rest of Settings
Section titled “The rest of Settings”Take the tour replays the first-run guided walkthrough. It is available any time.
The tour marks itself seen the moment it starts, not when it finishes. A user who leaves halfway has made that choice, and re-offering it on the next load would override them — so it stays out of the way until you ask for it again.
Run setup again reopens the onboarding wizard, which is the quickest route back to the printer presets if you want to switch wholesale rather than edit fields.
Where settings are stored
Section titled “Where settings are stored”In your browser, under a versioned key, alongside the draft of your current project. Nothing is transmitted anywhere.
Two things live there: whether you have completed onboarding and seen the tour, and your default printer profile. Everything else about a design is in the project file.
Clearing your browser’s site data resets them. Your saved .openchip files are
unaffected — they are files on disk.
