Compatibility matrix
This page separates two things that must not be confused:
- What NOPAL can do with each machine family. It comes from the code: the drivers and the API routes. It is verifiable.
- Which specific models have been tested. This is not in the code. Until real test reports exist, no model is declared "compatible": they are marked not verified.
1. Capabilities by family
Data from the drivers and the core REST API.
| Function | Klipper / Moonraker | Marlin | GRBL laser / CNC | Bambu Lab | Elegoo | FlashForge |
|---|---|---|---|---|---|---|
| Live status | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| Pause / resume / cancel | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| Start a job from NOPAL | ✅ | ✅ | ✅ | ✅ (send file) | ✅ (send file) | ✅ (send file) |
| Move the toolhead (jog) and home | ✅ (via G-code) | ✅ | ✅ | ❌ | ❌ | ❌ |
| Command console | ✅ | ✅ | ✅ | ❌ | ❌ | ❌ |
| Target temperature | ✅ | ✅ | — | ❌ | ❌ | ❌ |
| Print from SD card | — | ✅ | ✅ | — | — | — |
| Job queue | ✅ | — | ✅ | — | — | — |
| Scheduled prints | ✅ | — | — | — | — | — |
Edit printer.cfg and restart Klipper | ✅ | — | — | — | — | — |
GRBL $ settings | — | — | ✅ | — | — | — |
| Network discovery | Ports 7125–7127 on the server itself | ✅ (MKS WiFi) | ✅ (scan / by IP) | ✅ (passive SSDP) | ✅ | ✅ |
✅ implemented in the driver · ❌ the driver does not expose it · — not applicable to that family.
The Bambu Lab, Elegoo and FlashForge integrations only expose status, file sending and pause/resume/cancel. There is no movement or console.
2. Connection by family
| Family | Connection | How it authenticates |
|---|---|---|
| Klipper / Moonraker | HTTP (Moonraker) on the same server, ports 7125 to 7127 by default; plus those in NOPAL_KLIPPER_PORTS | Whatever Moonraker has |
| Marlin | USB serial, or MKS WiFi (UDP 8989 discovery and a TCP 8080 G-code bridge) | — |
| GRBL laser / CNC | Network (ESP3D or FluidNC boards) or USB serial | — |
| Bambu Lab | LAN mode: MQTT over TLS (port 8883) and FTPS to upload files | Serial number and access code |
| Elegoo | SDCP over WebSocket | IP and board identifier (mainboard_id) |
| FlashForge | HTTP, port 8898 | Serial number and check code |
Known limits
- MKS WiFi: the proprietary fast upload to the SD card is not supported.
- FlashForge: only the modern line (HTTP). Adventurer 3 and Adventurer 4 Pro/Lite, which use TCP with an exclusive session, are not supported.
- Elegoo: NOPAL implements the SDCP protocol directly. It does not use the official SDK or the MQTT of older resin printers.
- Bambu Lab: LAN mode only.
3. Models
What the code states
The code names these models. Naming them is not the same as having tested them.
| Family | Models named in the code |
|---|---|
| Elegoo | Centauri Carbon and Carbon 2, Neptune 4 series, OrangeStorm Giga |
| FlashForge | Adventurer 5M and 5M Pro, AD5X, Creator 5 and 5 Pro |
| Bambu Lab | X1 Carbon, X1, X1E, P1P, P1S, A1, A1 mini |
Built-in profile catalog
NOPAL includes a static catalog of machine profiles (work volume, firmware family, board variants). It is used to know what to show and offer when adding a machine; it does not change the machine's behavior.
The code itself states that the data comes from public datasheets or third-party reviews, not from tests against real hardware, with one exception: the Anet ET4 Pro profile, validated in Marlin's connection probe.
| Type | Included profiles |
|---|---|
| 3D printers (Marlin) | Hellbot Magna 2 300, Anet ET4 Pro, Snapmaker Artisan |
| 3D printers (Bambu Lab) | A1 mini, A1 |
| 3D printers (FlashForge) | AD5X |
| 3D printers (Klipper) | Creality K1C |
| Laser (GRBL) | Sculpfun S30 Pro, Two Trees TTS-55 Pro, xTool D1 Pro, Atomstack A5 Pro, Ortur Laser Master 3 |
| CNC (GRBL) | SainSmart Genmitsu 3018-PROVer and 4030-PROVer, Carbide 3D Shapeoko 4 Standard and Nomad, generic CNC 3018 |
Verification status
| Model | Status |
|---|---|
| Anet ET4 Pro | Validated by the author in Marlin's connection probe (per the code) |
| All the others | Not verified by this documentation |
The documentation team does not have these machines, so it cannot test them. The table stays at "not verified" until someone who uses them confirms it.
Report your hardware
If you use NOPAL with a specific model, tell us what works and what does not by opening an issue with the Tested hardware template in the documentation repository. Include model, firmware and which functions you saw working. With your report the row moves to stable, beta, partial or unsupported.
