Does the MakerGear M3 Dual 3D printer work with SimplyPrint, OctoPrint, Mainsail and Fluidd?
Each way of connecting it, what it needs, and how to set it up.
Doesn't ship with Klipper: it runs Klipper after you install it in place of its own firmware, a modification
What works with SimplyPrint
Connected through OctoPrint, SimplyPrint supports everything the MakerGear M3 Dual lets other software do: the camera and AI failure detection, remote printing, temperature and movement control and AutoPrint. 3 features depend on how it's set up: the table says what each needs.

What slicer to use for the MakerGear M3 Dual
None of the slicers in SimplyPrint's cloud has a ready-made profile for the MakerGear M3 Dual, 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 MakerGear M3 Dual.
Cloud-Based Slicer for MakerGear M3 Dual
All supported slicers - directly in your browser with SimplyPrint's online cloud slicer. No installation required. Slice your MakerGear M3 Dual 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 MakerGear M3 Dual: 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 MakerGear M3 Dual
SimplyPrint works as the MakerGear M3 Dual's app: on your phone and in any browser, with a slicer in the cloud.
There's no plate swapper or auto-ejection kit for the MakerGear M3 Dual in SimplyPrint yet, but AutoPrint can still keep it printing: once the plate is clear, it starts the next job from your queue.
Ways to automate it
Your own ejection G-codeWrite the routine that clears your plate, and AutoPrint runs it after every print.

What filament can the MakerGear M3 Dual print?
Filament compatibility for the MakerGear M3 Dual: 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
With care
The bed is hot enough, but ABS and ASA warp without an enclosure, which is strongly recommended for clean prints.
Nylon (PA)
With care
Possible with care - an enclosure and very dry filament are essential.
Polycarbonate (PC)
With care
On the edge - PC really wants an enclosed, hot chamber to avoid warping.
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.

MakerGear is a US printer maker from Beachwood, Ohio, near Cleveland, started by Rick Pollack in 2009 making extruder parts for early RepRap-style printers. Its steel-framed M2 (2012) became a long-running workhorse for engineers, businesses and schools, followed by the M3 series (2017) and the enclosed Ultra One (2018). In October 2026 its store lists the Ultra One and spare parts as available; the M2 and M3 show as unavailable.

Open: published firmware and design files, onboard OctoPrint with no cloud, and spare parts for printers going back to 2012. The concern is a quiet company rather than lock-in.
Firmware and custom firmware ●●●●●
MakerGear publishes its M2 and M3 firmware on GitHub (m3firmware is GPL-3.0) together with its OctoPrint setup; the firmware repositories were last updated in 2019, and upstream Klipper ships M2 configs.
[9][10][13][15]
Local control and integrations ●●●●●
The M3 and Ultra One run an onboard OctoPrint-based print manager over Wi-Fi or the network, and OctoPrint's REST API is documented. MakerGear publishes its OctoPrint setup plugin on GitHub; there is no MakerGear cloud or account.
[2][13][16]
Third-party filament, slicers and parts ●●●●●
Third-party filament and any slicer; MakerGear publishes Simplify3D profiles for its printers. Hot-end parts (V4 barrel, heater, nozzles) are MakerGear's own design but sold individually.
[8][4]
Repairs and spare parts ●●●●●
41 of 46 spare parts in MakerGear's store were in stock (hot-end parts, belts, fans, motors, LCDs, probes, power supplies), with upgrade and assembly guides, published M3 design files and printable Ultra One parts on GitHub.
[4][5][11][12]
Community and documentation ●●●●●
Public user and upgrade guides and GitHub repositories, and a long-standing M2 user base; but MakerGear's news page was last updated in 2019 and its repositories mostly in 2023-2024.
[6][7][8]
Pros
Steel-framed, long-lived printers with spare parts still sold for models back to 2012.
Firmware, OctoPrint setup and design files published on GitHub.
Onboard OctoPrint: control over your own network, no cloud account.
Designed and built in Ohio.
Cons
The M2 and M3 show as unavailable in MakerGear's own store (October 2026).
Little company news since 2019, and firmware repositories last updated in 2019.
Older designs: the newest printer on sale, the Ultra One, dates from 2018.
Track record
November 2021: MakerGear released the Micro, an open-source, 3D-printable printer kit, with its files on GitHub under GPL-3.0. The kit shows as unavailable in October 2026.
[14][3]
September 2018: MakerGear unveiled the Ultra One, its enclosed industrial printer, at IMTS in Chicago.

Can I use OrcaSlicer with the MakerGear M3 Dual?
Yes, but OrcaSlicer has no built-in profile for the MakerGear M3 Dual that we know of: start from a similar printer's profile and set the bed size, height and nozzle to match.
What filament can the MakerGear M3 Dual print?
Based on its specs (hotend up to 280C, heated bed up to 100C), the MakerGear M3 Dual handles PLA, PETG, or TPU & flexibles well. See the full filament guide above for ABS, nylon, PC and composites.
Does the MakerGear M3 Dual work with OctoPrint or Klipper?
The MakerGear M3 Dual works with OctoPrint, and SimplyPrint connects to it through them - so you get cloud access, a queue and camera monitoring on top.
What is the MakerGear M3 Dual's bed size and build volume?
The MakerGear M3 Dual has a 203 x 232 mm print bed and prints up to 203 mm tall, a build volume of about 203 x 232 x 203 mm. See the full specifications table above for bed type, temperatures and more.
