Why consider it?
A 64-bit Klipper board (1.5 GHz, quad-core) with Pressure Advance and Input Shaping enabled, 36-point auto bed leveling, and a dual pull-rod Z axis per Artillery.
What to verify
The frame stays open with no enclosure, so ABS benefits from a warm room. Exact box contents and included nozzles should be checked on the retailer's listing.
The specifications that matter
- Process

Which projects is it for?
The Sidewinder X4 Pro targets users who want Klipper firmware and a high advertised speed on a more compact footprint than the X4 Plus, with a 240 × 240 × 260 mm nominal build volume per Artillery, enough for most everyday parts.
The advertised top speed of 500 mm/s and 12,000 mm/s² acceleration per Artillery aim to cut print times without stepping up to a larger machine, a solid tradeoff for someone starting out with Klipper.
Materials and setup
The nozzle heats up to 300°C per Artillery, covering the advertised PLA, ABS, and PETG. Artillery's proprietary direct-drive extruder targets more precise extrusion, particularly on filaments that need tight retraction control.
36-point auto bed leveling and a dual pull-rod Z axis keep the bed stable over time, useful for a consistent first layer across repeated print sessions.
What the bundle includes or not
Artillery highlights WiFi, USB, and USB-C connectivity along with resume-after-power-loss printing. The exact box contents (spare nozzles, tools, cabling) should be checked on the retailer's listing before buying.
Klipper firmware with Pressure Advance and Input Shaping is advertised as enabled out of the box per Artillery, avoiding heavy manual tuning to reach the advertised top speeds.
Alternatives to compare
For a larger plate on the same Klipper base, the Sidewinder X4 Plus steps up to 300 × 300 × 400 mm per Artillery. For an enclosed chassis at a similar volume, the Creality Ender-3 V3 SE is worth comparing on budget.
The beginner's buying guide helps place this machine against other entry-level Klipper printers based on your speed and budget priorities.
