Genmitsu 4040-PRO: Current Specs, Sold-Out Status and MAX Comparison
The Genmitsu 4040-PRO still attracts substantial search demand even though the current Genmitsu storefront is sold out. It remains useful to understand because SainSmart continues to document the machine, and many shoppers need to know whether to wait, buy existing inventory, or move to the 4040-PRO MAX.
Genmitsu currently lists the 4040-PRO in its PRO-series navigation, while the exact storefront shows sold out. This page keeps the machine in the technical catalog but does not present sold-out manufacturer inventory as available.

The 400×400 mm work area is still the core reason to consider it
The base 4040-PRO is a meaningful step up from a 3018-class envelope. It can cover larger plaques, moderate signs, fixtures and many hobby parts without immediately moving into a 30-inch or 48-inch machine. But it is still a 400 mm square, so project size should be checked before the accessory list or sale price.
4040-PRO vs 4040-PRO MAX
The shared name hides a significant cutting-system difference. The current base 4040-PRO specification lists a 75W spindle, while the 4040-PRO MAX includes a 710W trim router. Both are in the same 400×400 mm horizontal class, so the MAX is not mainly a work-area upgrade.
The MAX also documents a different X/Z motion arrangement and a much more complete current feature set. If you are choosing between them today, use the preloaded 4040 comparison rather than assuming the MAX name simply means a larger frame.
The base spindle can be upgraded, but that does not transform the whole machine
SainSmart documents 52 mm motor options and separate 65/69 mm router mounts. Those paths give the platform room to grow, but a higher-power router does not change the frame, drive system, work area or every other part of the machine. Use the Spindle/Router Upgrade guide to check the complete upgrade path.
Rotary, laser and extension support are real—but exact compatibility still matters
SainSmart maintains a dedicated 4040-PRO resource center, a specific rotary-axis path and extension documentation. That makes the 4040-PRO unusually expandable for its class. It also means similar-looking 4040 accessories should not be treated as interchangeable without checking the exact supported machine.
Buying options when the manufacturer page is sold out
If the technical fit is right, you can check current marketplace results without assuming an exact listing is in stock. The broad Genmitsu Amazon route is intentionally a search page rather than a pinned ASIN.
Compare before waiting for stock
Compare the 4040-PRO, 4040-PRO MAX and 3030-PROVer MAX, or use the Matcher to see whether a current machine from another brand is a stronger fit.

Frequently asked questions
Is the Genmitsu 4040-PRO still current?
Genmitsu still lists the 4040-PRO in its current PRO lineup, but its Genmitsu storefront page is currently sold out. SainSmart's current manufacturer page continues to document the exact 4040-PRO specifications.
What is the Genmitsu 4040-PRO work area?
The current SainSmart manufacturer page publishes a 400×400×78 mm work area, about 15.75×15.75×3.1 inches.
What spindle comes with the 4040-PRO?
The current SainSmart specification lists a 75W spindle with a published 9,000 RPM maximum. The platform also has documented larger 52, 65 and 69 mm mount paths, but those are upgrades rather than the included cutting system.
What is the difference between 4040-PRO and 4040-PRO MAX?
Both use a 400×400 mm X/Y envelope. The PRO MAX moves to a 710W trim router and a different X/Z motion package, while the base 4040-PRO uses lead-screw drive and a much smaller included spindle.
Does the 4040-PRO support rotary and laser accessories?
Yes. Current SainSmart documentation includes dedicated 4040-PRO resource, extension, rotary and laser support paths. Verify the exact accessory before buying rather than assuming every 4040 accessory is interchangeable.
