Doesn't ship with Klipper: it runs Klipper after you install it in place of its own firmware, a modification
What slicer to use for the Longer Cube 2
None of the slicers in SimplyPrint's cloud can slice for the Longer Cube 2 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 Cube 2.

What filament can the Longer Cube 2 print?
Filament compatibility for the Longer Cube 2: the materials Longer lists for it.
Filament
Suitability
Notes
PLA
Great
On the maker's list of materials for this printer.
PETG
With care
Marginal - PETG prefers a hotter bed (~70-80C) than this printer reaches.
TPU & flexibles
With care
Possible, but a Bowden extruder makes flexibles harder - print slowly and prefer firmer (higher-shore) TPU.
ABS & ASA
Great
On the maker's list of materials for this printer.
Nylon (PA)
Not ideal
Not recommended - nylon needs a hotter hotend (~250-270C) and ideally an enclosure.
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.
