The RX6040 has a 600 x 400 x 130 mm effective processing area. It runs a 1.5kW spindle (65mm) with ER11 1/8in and 1/4in collets up to 24,000 RPM, HGH-15 dual linear rails and 1204 ball screws on all three axes, and Nema 23 steppers rated 2.8A, 1.2 N·m.
Every cut starts with one formula: Feed Rate = Spindle Speed (RPM) x Chip Load x Number of Cutting Edges (flutes). Chip load is the thickness of material each cutting edge removes in one revolution of the bit. This number comes from the manufacturer of the bit, which publishes a chip-load chart for each bit diameter and material. Look up your exact bit and material, start from the middle of the published range, and you have the third number in the formula. The chart below shows the recommended spindle speed for each material and bit type.
The RX6040's 1.5kW spindle runs up to 24,000 RPM, covering the full range of the chart below and then some, and it holds more torque under load than the smaller trim-router-based machines in AnoleX's lineup. Its HGH-15 dual linear rails and 1204 ball screws on all three axes, driven by Nema 23 steppers, are a rigid setup for a desktop machine, which supports deeper passes than a lighter lead-screw or belt-driven router. A truly rigid machine capable of cutting as deep as the bit is wide in one pass also needs clamps that hold firm and enough mass to soak up vibration, so work up to depth rather than assume it on the first pass. Push too deep too fast and the bit deflects and chatters, leaving scalloped edges, or it rubs instead of cutting and burns the material. The fastest way to dial in a cut is to see what has already worked for other people.
Worked example for feed rate: 1/8in (3.175mm) two-flute solid carbide end mill in hard wood. The chart says 16,000 RPM, and this spindle's 24,000 RPM top speed covers it, so run 16,000. With the bit maker's 0.025mm per tooth (0.0010 in): 16,000 x 0.025 x 2 = 800 mm/min (31 in/min) feed. For depth per pass, start shallow and check Community Cut Settings in Easel for what works on this machine. If the cut sounds strained, reduce the depth, not the feed. Slowing the feed below the chip load makes the bit rub instead of cut.
Community Cut Settings shows the spindle speed, feed rate, and depth per pass other makers actually run for your machine, material, and bit.
The RX6040 connects over USB through the free Easel Driver: install the driver on your Mac or Windows computer, plug the machine in, and Easel talks to it in real time. You design in the browser, Easel generates the toolpaths, and the Carve button walks you through homing, zeroing, and starting the cut. Pick RX6040 from Easel's machine menu during setup and the canvas is sized to the machine's 600 x 400 x 130 mm working area, so your preview matches what the machine can actually cut.
