For a CNC router purchase in industrial woodworking machinery, the key question is whether a small price gap reflects a machine difference that matters to your work. Here, both 4040-PRO options share the same 3-axis router format, CNC control, USB connection, GRBL/Candle software support, and 400 × 400 × 83 mm effective stroke. The decision comes down to price priority, package details, and which stated specifications you want to anchor your choice around.
Quick verdict
The listed-price spread is just USD 0.17, so neither option changes the overall spending level. The USD 363.39 4040-PRO is the straightforward price-led pick and has a specifically itemized package. The USD 363.56 4040-PRO is the alternative for shoppers who want its description's stated radial-runout and stepper-motor specifications to be part of the decision.

Where each 4040-PRO wins
The USD 363.39 4040-PRO wins the price comparison by USD 0.17. Its package description also names a cutter, Z probe, USB, power supply, power cable, four clamps, manual, right-y-axis, and U Disk, making it the clearer choice when an itemized starting accessory set is useful to your setup.
The USD 363.56 4040-PRO is the more suitable choice when its stated mechanical figures are your priority. Its description specifies radial runout of no more than 0.05 mm, a 42 two-phase stepper motor, and a 6000 rpm rotation speed. Those are concrete specification points for a shopper who wants to select around those figures rather than around the small price difference.
Product notes
4040-PRO CNC Router - USD 363.39
Choose this 4040-PRO when the lower listed price is the deciding factor and you prefer an accessory package that is clearly enumerated. The named cutter, Z probe, clamps, power components, USB, U Disk, manual, and installation accessories give this version a well-defined starting bundle. It retains the same 400 × 400 × 83 mm working stroke, CNC control, USB communication, and GRBL/Candle compatibility shared by the other option, so it fits a buyer focused on the common core router configuration. Its limitation is that the shared control, software, connection, spindle power, and working-area specifications do not establish a distinct machine-spec edge over the USD 363.56 version.
4040-PRO CNC Router - USD 363.56
Select this 4040-PRO if the explicitly stated radial-runout and motor details help you make a more specification-focused choice. The description names radial runout of up to 0.05 mm and identifies a 42 two-phase stepper motor with a stated 6000 rpm rotation speed. That gives this version a concrete appeal for buyers organizing their decision around those mechanical figures. It otherwise carries the same core 3-axis CNC format, USB connection, GRBL/Candle support, effective stroke, and stated engraving-speed range as its counterpart. The limitation is its listed price: it is USD 0.17 higher while the main router-control and workspace specifications remain shared.
Final choice by use case
Pick the USD 363.39 4040-PRO for a price-led decision or when the named cutter, Z probe, clamps, and other package items are especially relevant. Pick the USD 363.56 4040-PRO when the stated 0.05 mm radial-runout figure and stepper-motor details are the specifications you want to prioritize. For shoppers whose work centers on the shared CNC workspace, USB control, and GRBL/Candle operation, the lower-priced version is the more direct choice.
