The LK10 Plus is a large-format, Klipper-based bedslinger from Longer with a 320 x 320 x 400 mm plate and speeds up to 500 mm/s. It is for hobbyists who want a big plate at a low price.
Does the Longer LK10 Plus 3D printer work with SimplyPrint, OctoPrint, Mainsail and Fluidd?
Each way of connecting it, what it needs, and how to set it up.
Longer says it ships Klipper on a 'Klipper high-speed board', and the manual connects OrcaSlicer over LAN with the 'Octo/Klipper' host type, which suggests Moonraker, but no source names Moonraker, Mainsail or Fluidd. Check port 7125 on a unit.

None of the slicers in SimplyPrint's cloud can slice for the Longer LK10 Plus that we know of: it doesn't take standard G-code. Use the slicer its maker recommends.
We only list slicers you can use in the SimplyPrint cloud, so there may be others for the Longer LK10 Plus.

Suitability
Notes
PLA
Great

PETG
Great
On the maker's list of materials for this printer.
TPU & flexibles
Great
On the maker's list of materials for this printer.
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)
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.
When to choose the Longer LK10 Plus
Choose the LK10 Plus when build size matters more than enclosure or multi-material, and you print PLA, PETG, ABS, ASA or TPU. Longer lists it on sale at 419.99 USD (regular 549.99) with automatic eddy-current levelling and a 25 mm³/s high-flow direct-drive extruder. We found no independent review, so its speed and quality claims are the maker's own. For enclosed, easy-to-run printing choose a Bambu Lab P1S instead, and note its SimplyPrint connection is not confirmed here.
Pros
Very large 320 x 320 x 400 mm build volume for the price (Longer).
Klipper-based high-speed mainboard, up to 500 mm/s, with a high-flow extruder rated up to 25 mm³/s (Longer).
Automatic bed levelling with an eddy-current sensor and automatic Z offset (Longer).
Prints PLA, PETG, ABS, ASA and TPU, with Wi-Fi and a 4.3-inch colour touchscreen.
Sale price of 419.99 USD and a 12-month warranty (Longer).
Cons
Open frame with no enclosure, so ABS and ASA are harder to print well and hot parts are within reach.
A moving bed at this size can limit quality at high speed; the 500 mm/s figure is a maker claim with no independent test.
SimplyPrint compatibility is unknown for Klipper and unlikely for OctoPrint, so connecting is not assured.
No built-in camera is listed, and no independent review was found.
Who it suits
SchoolsNot a good fit
An open frame with a large moving bed is not safe or quiet enough for a classroom, and a SimplyPrint connection is not confirmed.
HobbyistsGood fit
A large plate and Klipper at a low price suit tinkerers, though the quality claims are untested by independent reviewers.
BusinessesCan work
The size helps with big prototypes, but there is no enclosure and no independent evidence of reliability.
Print farmsNot a good fit
No listed camera, an open frame and an unconfirmed SimplyPrint connection make it a weak fit for many machines running unattended.
