Each way of connecting it, what it needs, and how to set it up.
Ships with Klipper: OctoPrint only runs on top of it, through the OctoKlipper plugin
What works with SimplyPrint
Connected through Klipper (Moonraker), SimplyPrint supports most of what it offers on the IdeaFormer IR3 V2: the camera and AI failure detection, remote printing, skipping objects, temperature and movement control and AutoPrint.

What slicer to use for the IdeaFormer IR3 V2
None of the slicers in SimplyPrint's cloud has a ready-made profile for the IdeaFormer IR3 V2, but it takes standard G-code: start from a similar printer's profile and set the bed size, height and nozzle to match.
We only list slicers you can use in the SimplyPrint cloud, so there may be others for the IdeaFormer IR3 V2.
Cloud-Based Slicer for IdeaFormer IR3 V2
All supported slicers - directly in your browser with SimplyPrint's online cloud slicer. No installation required. Slice your IdeaFormer IR3 V2 models from any device, anywhere in the world!
Automatic Profile Updates: Profiles are automatically checked and fetched from the slicer GitHub repositories every day, as well as from our own open-source community-driven slicer profile database. This ensures you always have access to the latest profiles.
Note: Other slicers, such as Simplify3D, ideaMaker, SuperSlicer and KISSlicer, aren't in our cloud, so we don't track their profiles. They may still work well with your IdeaFormer IR3 V2: check the slicer's own documentation or forums for a profile. You can also contribute profiles to our open-source slicer profile database on GitHub.
The app for the IdeaFormer IR3 V2
IdeaFormer doesn't make an app for the IdeaFormer IR3 V2. SimplyPrint works as its app: on your phone and in any browser, with a slicer in the cloud.
SimplyPrint's AutoPrint keeps the IdeaFormer IR3 V2 printing: it starts the next job from your queue after each print.
A belt printer automates itself
The IdeaFormer IR3 V2 prints onto a conveyor belt that carries each finished print away, so it needs no plate swapper or ejection kit: AutoPrint starts the next job from your queue as soon as the last one has moved off.

Great

ABS & ASA
Great
On the maker's list of materials for this printer.
Nylon (PA)
With care
Possible with care - an enclosure and very dry filament are essential.
Polycarbonate (PC)
Not ideal
Not recommended - PC needs very high hotend temps and an enclosed chamber.
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.
Tip: this is a general guide from the printer's specs - always check your filament's recommended settings. With SimplyPrint you can save a profile for each spool and track exactly what filament you have in stock.

Reviews from people who test printers for a living. We link to them; the opinions are theirs.
The Edge of Tech · November 19, 2024
Hands-on with the CoreXY belt printer that prints at an angle onto a PEI-coated metal belt. Finds it the easiest belt printer he has used and very functional, good for very long parts and batch production, with a Kickstarter warning to back it only with disposable money.
Aurora Tech · October 24, 2024
Tests a prototype IR3 V2 before its Kickstarter: easy assembly, auto-leveling and auto Z offset, 2-3x the speed of Marlin belt printers, strong cooling. Cons: some printed parts, untuned slicer profiles, no direct upload from the slicer. Sponsored by IdeaFormer (disclosed in the video); stresses Kickstarter risk.
The Next Layer · October 22, 2024
First look at the IR3 V2: how a belt printer differs from a normal one, what it makes possible (much longer parts, queued prints running unattended through remote access) and the new overhang and orientation rules to learn. Printer supplied and video sponsored by IdeaFormer, disclosed.

IdeaFormer is a Chinese company in Zhuhai, founded in 2017 as a maker of 3D printer accessories, that has built belt printers since 2020. Its IR3 V2 prints onto an endless metal conveyor belt, so parts can be longer than the machine and batches run without anyone clearing the bed; it runs Klipper. It suits makers and small shops with long parts or repeat runs.

Klipper with a local web interface, OrcaSlicer support and a full parts list; the firmware comes as images rather than source, and documentation is thin.
Firmware and custom firmware ●●●●●
The IR3 V2 runs Klipper, and IdeaFormer publishes full system images and USB update files (latest dated 30 September 2026), but we found no source repository.
[4][2]
Local control and integrations ●●●●●
The IR3 V2 runs Klipper and prints from a USB drive, the local network or the internet, with remote control and a camera from a phone or computer; IdeaFormer mentions no cloud service or account. Its pages do not name the web interface or say whether a documented API such as Moonraker is open to other software, so that part is unconfirmed.
[3]
Third-party filament, slicers and parts ●●●●●
Any filament; OrcaSlicer ships an IR3 V2 profile next to IdeaFormer's own OrcaSlicer-based slicer, and IdeaFormer sells brass and hardened steel nozzles from 0.4 to 1.0 mm. The belt, rollers and print head are IR3-specific parts.
[7][3][5]
Repairs and spare parts ●●●●●
IdeaFormer sells about 30 IR3 V2 parts, including the belt, mainboard, motors, rollers, sensors, camera and print head boards. It publishes no CAD files.
[5]
Community and documentation ●●●●●
IdeaFormer's wiki says it is still under construction; there is a forum and an IR3 Facebook user group, and no public source code.
[6][1]
Pros
Prints parts longer than the machine and runs batches without anyone clearing the bed.
Klipper with the Fluidd web interface on your own network.
Full spare-parts list, from the belt to the mainboard.
Still getting firmware and slicer updates in 2026.
Cons
Belt printing needs its own slicing approach, and IdeaFormer's latest slicer release is an alpha.
No published firmware source, only system images.
Thin documentation: IdeaFormer's wiki says it is still under construction.
Track record
September 30, 2026: IdeaFormer posted new IR3 V2 system images, USB update files and an alpha slicer release (v2.1.4-alpha).
[4]
2020: IdeaFormer moved from accessories to complete printers with its first IR3 belt printer.
