Genmitsu 4040-PRO MAX: What the Current Specifications Actually Mean
The 4040-PRO MAX is not simply “the bigger 4040.” It keeps the same 400 × 400 mm X/Y envelope as the 4040-PRO while changing the vertical capacity, included cutting system and documented feature set. This page separates those verified differences from assumptions so you can decide whether the MAX actually fits your projects.
Specifications below come from the normalized current record and manufacturer sources. Affiliate availability does not change the machine’s editorial fit or comparison position.
4040-PRO MAX at a glance
The 4040-PRO MAX is a square benchtop CNC router in Genmitsu's 400 mm class. Its strongest verified differences are not a larger X/Y envelope, but the included 710W trim router, 78 mm Z figure, 100 mm published pass height, reinforced spoilboard support and a more completely documented control/accessory package.

The 400 × 400 mm envelope is the first hard decision
A 400 × 400 mm work area is useful for moderate signs, plaques, craft parts, fixtures and many desktop projects, but it is still a hard one-setup limit. The machine dimensions are about 660 × 666 mm before you account for stock access, dust collection, controller/computer space and operator clearance.
If you are choosing the 4040-PRO MAX mainly because “4040 sounds large,” use the Work Area Calculator with your actual largest part and clamp margin first. A larger machine can be the better purchase even when the MAX has stronger features.
Why the 710W router matters—and what it does not prove
The exact current configuration includes a 710W digital trim router with a wide published RPM range. That is materially different from small 60W/300W spindle-class starter machines and removes one separate purchase from the base setup.
It still should not be converted into a universal performance score. Router power alone does not prove rigidity, chip evacuation, tool engagement, alloy suitability or production rate. The manufacturer does explicitly document aluminum, so the machine can enter an aluminum-required shortlist on evidence; the actual job still depends on tooling, workholding, feeds/speeds and cut strategy.
4040-PRO MAX vs 4040-PRO
The two machines share the same current 400 × 400 × 78 mm work-area specification, so the MAX is not primarily a work-area upgrade. The base 4040-PRO uses a 75W spindle and lead-screw drive, while the MAX includes the 710W trim router and uses a different documented X/Z motion package. The MAX also publishes a 100 mm pass-height figure and a more complete current control/accessory package.
The 4040-PRO remains a current documented model, but its Genmitsu storefront is sold out. CNC Router Match therefore keeps it in the technical lineup while treating availability separately from the MAX buying path.
Check the MAX against a different architecture
If the project fits a 400 mm square, compare the MAX with the PROVerXL 4030 V2. The 4030 V2 gives up 100 mm of Y work area but adds verified all-axis 1204 ball screws and closed-loop motors. Or use the CNC Router Matcher to let your actual requirements drive the shortlist.
Accessory and expansion context
Genmitsu states that the 4040-PRO MAX is compatible with most 4040-PRO accessories and documents rotary/4th-axis and laser support. The manufacturer specifically qualifies extension compatibility: the MAX supports the Y-axis extension path rather than implying every 4040 extension arrangement is interchangeable.
That distinction matters. Accessory compatibility should be verified by the exact machine and accessory relationship, not inferred from the shared 4040 name.
Buying path after the technical fit is clear
CNC Router Match recorded current manufacturer-direct and Amazon marketplace presence during the September 3, 2026 commercial audit. The Amazon route is a targeted search path rather than a pinned unverified ASIN so OneLink can still handle regional routing.
Relevant upgrade planning
The 4040-PRO MAX already includes its 710W trim router, but its work area can be expanded using current Genmitsu 6040/4060 hardware. Use the Extension Kit Finder before buying rails or spoilboards, and use the Setup Cost Calculator if the expanded footprint changes the table, dust or workholding budget.
Laser-module compatibility
If you plan to add a laser, check the exact module for this machine rather than assuming any module from the same brand will fit. The CNC Router With Laser guide shows the currently documented compatible modules and the safety requirements to review before use.
Manufacturer sources
The included router, Z probe and collets are separate compatibility details
SainSmart currently lists an LED Z probe and ER11 collets with the 4040-PRO MAX. Use the Touch Probe guide for the broader zeroing/tool-setter distinction and the Collet guide before buying different shank sizes or considering a spindle upgrade.
Frequently asked questions
What is the Genmitsu 4040-PRO MAX work area?
The current exact manufacturer specification publishes a 400 × 400 × 78 mm active area, about 15.75 × 15.75 × 3.1 inches. The manufacturer separately publishes a 100 mm Z-pass-height figure, which is not the same thing as guaranteed cutting depth.
Does the Genmitsu 4040-PRO MAX include a router?
Yes. The normalized current configuration includes a 710W digital trim router with a published 6,500–30,000 RPM range and a 65 mm mount.
Can the Genmitsu 4040-PRO MAX cut aluminum?
The current manufacturer page explicitly includes aluminum in its material claims. That supports aluminum capability as a documented use, but it does not guarantee a particular alloy, depth of cut, finish, feed rate or production rate.
How is the 4040-PRO MAX different from the 4040-PRO?
Both normalized records use a 400 × 400 mm X/Y work area. The MAX record adds a 78 mm Z figure, a published 100 mm pass height, a 710W trim router and substantially more verified control, safety and accessory detail.
Can I compare the 4040-PRO MAX with other CNC routers?
Yes. Use the preloaded Compare view for exact side-by-side fields, or use the CNC Router Matcher when you want project size, material, workload and setup preferences to determine the shortlist across brands.
