Sidewinder X4 Pro S1
Fused filament fabrication (FFF/FDM)
F2 · Intermediate
Those who choose the Sidewinder X4 Pro S1 forgo a €200 printer with Marlin and V-roller guides, gaining preinstalled Klipper, input shaping, and linear rails on X and Y, maintaining quality at 500 mm/s. Compared to €450-500 CoreXY solutions, it lacks an enclosed chamber and multi-material filament changing, but for those printing PLA and PETG prototypes daily, the extra cost doesn't pay off with the same usage frequency. The actual 240x240x260 mm build volume covers 90% of projects, but those needing 300x300 mm find alternatives at the same price. The biggest limitation is the absence of an enclosure for ABS and ASA.

Software
Native Klipper firmware with a 64-bit ARM 1.5 GHz processor. The printer is controlled via Wi-Fi from the Fluidd or Mainsail web interface, sending G-code from any slicer (Cura, PrusaSlicer, OrcaSlicer). No proprietary software required; USB/Type-C connection allows offline control. The user has full access to macros and advanced Klipper tuning, without hardware modifications.
Reviews from those who use this machine every day will be available in the next version of the platform.
