Pro CNC 4040-PRO vs 4040-PRO + RC: Which Router Kit Should You Buy?

The base Pro CNC 4040-PRO and the + RC version share the same 400x400mm work area, 75W spindle, and GRBL/Candle support. The real difference is the price: $331.39 for the base machine versus $438.34 for the + RC package.

Last updated Aug 17, 2026

When you're outfitting a shop for industrial woodworking, the router you choose needs to handle tough materials like metal, acrylic, and MDF without making you second-guess the purchase. Two versions of the Pro CNC 4040-PRO have likely ended up side by side in your search: the standard 4040-PRO and the 4040-PRO + RC. They look nearly identical, share the same specifications, and differ mainly in name and price. The base machine is the lower-priced entry, while the + RC version carries a noticeable premium. So which one belongs in your workshop?

Quick Verdict

If you want the full 4040-PRO cutting performance without paying extra, the standard Pro CNC 4040-PRO is the straightforward pick. If you specifically want the version listed with the + RC add-on and can absorb the higher cost, the 4040-PRO + RC is the one to choose. Both deliver the same 75W spindle, 400x400mm stroke, and GRBL/Candle compatibility, so the decision comes down to whether the RC variant is worth the premium to you.

Where Each Product Wins

  • The standard 4040-PRO wins for budget-focused shoppers: it carries the lower price and the same cutting envelope, spindle, and software support as the pricier version.
  • The 4040-PRO + RC wins for shoppers who want the explicitly named RC bundle: the + RC suffix is the only package-level difference in the listings, so if that's a must-have, this is your version.

The standard Pro CNC 4040-PRO is the lower-priced way into the 4040-PRO platform. For $331.39, you get the same 400x400x83mm effective stroke, 75W spindle, 12V 5A drive, and GRBL/Candle software support as the + RC version. That makes it the sensible choice when your budget matters more than the RC label. The practical limitation is that the title doesn't include the + RC suffix, so you won't have that add-on in the package name; if the + RC feature is the reason you're looking at the second listing, the standard version will leave you wanting.

The 4040-PRO + RC asks for $438.34 and gives you the same core cutting capabilities as the base machine, but it's the listing that carries the + RC designation. If you've already decided that the RC version is the one you want, this is the product to add to your cart. The description also notes the aluminum frame construction and a 75W high-power spindle motor designed for efficient engraving, which is a reassuring detail at this higher price point. The limitation is that the listed specifications don't show any additional stroke, spindle power, or software differences over the base version, so you're paying the premium primarily for the RC add-on as named.

Final Choice by Use Case

Choose the standard Pro CNC 4040-PRO if you want the same cutting performance as the pricier model and don't need the + RC designation. The $331.39 price keeps more money in your pocket for bits and materials.

Choose the Pro CNC 4040-PRO + RC if the + RC add-on is part of your plan and you're okay with the $438.34 price. You'll get the same 400x400mm work area, 75W spindle, and USB connection, plus the RC-labeled package.

If you're still on the fence, weigh the $106.95 gap: the base machine gives you identical core specs and a lower price, so it's the better default unless the RC bundle is essential.
