Some printers won't print with the door open (the Prusa CORE One has a door sensor), so check yours first. ### Ways to automate it - [Push prints off with the toolhead](https://simplyprint.io/features/autoprint/push-off): On a CoreXY printer, a G-code routine can push the cooled print off the front of the plate before the next job starts. - [Your own ejection G-code](https://simplyprint.io/features/autoprint/custom): Write the routine that clears your plate, and AutoPrint runs it after every print. - [A robot arm, or anything with an API](https://simplyprint.io/features/autoprint/api): Tell SimplyPrint the plate is clear through the API or a webhook, from a robot arm or your own system. - [Clear it by hand, keep the queue](https://simplyprint.io/features/autoprint/manual-mode): AutoPrint waits for you to mark the plate clear, then starts the next job. [How AutoPrint works](https://simplyprint.io/features/autoprint).

Filament compatibility for the QIDI Max4 Combo: the materials it can handle, judged from its hotend, bed, chamber and enclosure. | Filament | Suitability | Notes | | :--- | :--- | :--- | | PLA | Great | The easiest filament to print. Works on almost any printer; a heated bed helps adhesion but is not required. | | PETG | Great | Comfortably in range (PETG likes a ~230-250C hotend and a ~70-85C bed). | | TPU & flexibles | Great | The direct-drive extruder feeds flexible filament well. Print slowly for clean results. | | ABS & ASA | Great | Enclosed, with a hot enough hotend and bed: ABS and ASA print well. | | Nylon (PA) | Good | Doable with care - dry the filament thoroughly, and an enclosure helps a lot. | | Polycarbonate (PC) | Good | In range for PC. Dry the filament, print slowly, and use an enclosure for the best results. | | Carbon-fiber & glass-filled | With care | Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle. | ### Best filament for the QIDI Max4 Combo Filaments the QIDI Max4 Combo prints well, QIDI's own first, then the best known. - [QIDI Tech ASA](https://simplyprint.io/filaments/qidi-tech/asa): ASA, 240-280 °C - [QIDI Tech Odorless ABS Rapido](https://simplyprint.io/filaments/qidi-tech/abs-odorless-rapido): ABS, 240-280 °C - [QIDI Tech PLA Basic](https://simplyprint.io/filaments/qidi-tech/pla-basic): PLA, 190-240 °C - [QIDI Tech PLA Rapido](https://simplyprint.io/filaments/qidi-tech/pla-rapido): PLA, 200-240 °C - [Bambu Lab PLA Basic](https://simplyprint.io/filaments/bambu-lab/pla-basic): PLA, 190-230 °C - [Bambu Lab PLA Matte](https://simplyprint.io/filaments/bambu-lab/pla-matte): PLA, 190-230 °C - [SUNLU PLA](https://simplyprint.io/filaments/sunlu/pla): PLA, 200-240 °C - [Anycubic PETG](https://simplyprint.io/filaments/anycubic/petg): PETG, 230-250 °C ## What reviewers say about the QIDI Max4 Combo - [I Tested QIDI’s Biggest Printer… Here’s the Truth (Max4)](https://www.youtube.com/watch?v=XGnYiR_-pDU) (ModBot, May 2, 2026): Several months with a unit the maker offered for testing. Likes the steel frame, load-cell first layers, chamber heater and hotend; dislikes the sketchy screen cable, rear cable management, weak filament profiles and the noisy, slow Qidi Box. Would pick the smaller Q2 for polish. - [QiDi Max 4 3D Printer Review – 390×390×340mm, 370°C Nozzle, 65°C Chamber for Engineering Filaments](https://www.youtube.com/watch?v=ZyHpGiBHPVY) (Aurora Tech, March 26, 2026): Qidi sent the unit and sponsored the video (disclosed). Praises the robust hardware, 370°C nozzle and 65°C chamber, ideal for engineering filaments and good value at about $1,049. The multi-filament box is slow, adding 60-70 s per swap, and drips water, so he advises against it for multicolor PLA. ## Compare the QIDI Max4 Combo with similar printers - [Bambu Lab H2S Combo](https://simplyprint.io/compatibility/bambu-lab-h2s-combo): Verified by SimplyPrint, 340 x 320 x 340 mm, Similar build volume · Also prints ABS & ASA, Nylon (PA), Polycarbonate (PC) · Multi-material too - [Bambu Lab H2D Combo](https://simplyprint.io/compatibility/bambu-lab-h2d-combo): Verified by SimplyPrint, 325 x 320 x 325 mm, Similar build volume · Also prints ABS & ASA, Nylon (PA), Polycarbonate (PC) · Multi-material too - [Creality K2 Plus Combo](https://simplyprint.io/compatibility/creality-k2-plus-combo): Compatible, 350 x 350 x 350 mm, Similar build volume · Also prints ABS & ASA, Nylon (PA), Polycarbonate (PC) · Multi-material too - [Bambu Lab H2C Combo](https://simplyprint.io/compatibility/bambu-lab-h2c-combo): Verified by SimplyPrint, 330 x 320 x 325 mm, Similar build volume · Also prints ABS & ASA, Nylon (PA), Polycarbonate (PC) · Multi-material too - [Compare the QIDI Max4 Combo with other printers](https://simplyprint.io/compatibility/compare?compare=qidi-max4-combo#choose) ## Where to buy the QIDI Max4 Combo _QIDI sends us some of its new printers free of charge._ - [QIDI for the EU](https://simplyprint.io/buy/8117) (Official store) (Affiliate link) - [QIDI for the UK](https://simplyprint.io/buy/8118) (Official store) (Affiliate link) - [QIDI for the US](https://simplyprint.io/buy/8116) (Official store) (Affiliate link) - [QIDI's global store](https://simplyprint.io/buy/8115) (Official store) (Affiliate link) - [View at TECBEARS](https://simplyprint.io/buy/8120) (Affiliate link) - [QIDI Max4](https://simplyprint.io/compatibility/qidi-max4): Also sold without the multi-material unit. ## About QIDI QIDI Tech is a Chinese 3D printer maker formed in 2014. It sells enclosed, Klipper-based CoreXY printers such as the compact Q2 and the larger Plus4 and Max4, and develops the open-source QIDI Studio slicer and the QIDI Link app. - Founded: 2014 - Website: https://qidi3d.com Openness: Mostly open (4.2 of 5) QIDI is mostly open: its printers are standard Klipper machines you can run fully on the local network, with published source and plenty of spare parts. The phone app and the store-only privacy policy are the weak spots. - Firmware and custom firmware (4 of 5): QIDI printers run QIDI's editions of Klipper and Moonraker with Fluidd. QIDI publishes them and per-model firmware packages on GitHub under GPL (for example the Q2 in January 2026 and the Max4 in August 2026) and answers issues there. - Local control and integrations (5 of 5): QIDI printers run Klipper and Moonraker with Fluidd on the printer, and QIDI Studio connects to them on the local network by IP without an account. QIDI publishes its Moonraker edition on GitHub, and other software can use Moonraker's documented API. Only the QIDI Link phone app needs an account and QIDI's cloud. - Third-party filament, slicers and parts (4 of 5): Third-party filament works; QIDI Studio is open source, and as Klipper and Moonraker printers they work with other Moonraker-compatible software. Hotends and nozzles are QIDI parts made per model. - Repairs and spare parts (4 of 5): QIDI's store lists many individual parts, including motherboards, eMMC modules, fans, extruders, hotends and Wi-Fi cards, and its wiki has replacement guides such as the Plus4 hotend. - Data and privacy (3 of 5): Local use needs no account. QIDI Link requires one and says which server it uses (Aliyun in China, AWS elsewhere). The published privacy policy covers the online store, not the printers or the app. - Community and documentation (4 of 5): Firmware is released and issues are taken on GitHub, and QIDI keeps a wiki per model with manuals, maintenance and troubleshooting guides. ### From SimplyPrint Our own experience working with QIDI. It isn't part of the rating. - QIDI is one of the few printer makers we work with directly: they occasionally send us new printers, and put us in touch with their developers when we need them. ### Pros - Runs fully on the local network through Fluidd, with no account needed. - Klipper and Moonraker sources and firmware updates are published on GitHub. - Many individual spare parts, down to motherboards and eMMC modules. - Open-source slicer and open filament choice. ### Cons - The QIDI Link app needs an account and QIDI's cloud. - The privacy policy covers only the online store, not the printers or app. - Hotends and nozzles are QIDI-specific parts. ### Track record - August 2026: QIDI published the firmware repository for the Max4 on GitHub under GPL-3.0. - January 2026: QIDI published the Q2's Klipper-based firmware on GitHub under GPL-3.0, with update packages and an issue tracker.
