Genmitsu 3020-PRO Ultra, 710 W spindle, HG15 rails review
The dearest of the three routers on this site, an all-metal machine on dual HG15 linear guides with a 710 W variable-speed spindle and an offline controller, whose listing claims 1.5 mm aluminium cuts per pass but gives no working area.
The bottom line Mechanically the best-described router of the three: linear guides, spindle range, torque, collet, controller. It omits the dimension every buyer asks first, and the software and limit switches that a router owner relies on.
The 3020-PRO Ultra listing, bullet by bullet
Five bullets: all-metal construction with dual HG15 linear guides and a reinforced X-axis back plate; 60 mm stepper motors with up to 7.3 Nm of torque, cutting aluminium up to 1.5 mm deep in one pass; a 710 W spindle from 6,500 to 30,000 rpm in six speed steps with constant torque control, for solid wood, metal, acrylic, carbon fibre and titanium, with a 1/8 in ER11 collet; an integrated offline controller with an optional MPG port and a modular build; and a one-piece aluminium work surface, a Ø65 mm spindle holder and Ø52 mm adapter, compatible with Ø69 mm holders.
Rigidity, described in parts
HG15 guides, a reinforced back plate and 7.3 Nm steppers. Each is a named component rather than an adjective, and together they explain why the listing talks about aluminium and titanium at all.
The size the Genmitsu page leaves out
3020 is a model name, and the page never turns it into millimetres. A working area inferred from a model number is not a published figure, so this review leaves the row empty and points to the maker’s documentation.
Software and switches, both unmentioned
An offline controller runs jobs without a computer attached, but the program that prepares those jobs is not named, and no limit switches are listed. Neither absence proves the machine lacks them; both are worth checking with Genmitsu rather than assuming.
Availability
At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 552 € to 646 €.
It is sold in the American and British Amazon stores as well, in their own currency, which the euro figures above leave out on purpose.

Questions makers ask before buying
What is its working area?
The listing does not say. The model name suggests a size class, but no dimension is given in the title or bullets, and this page does not infer one.
Can it take a laser module?
The fifth bullet says the Ø65 mm spindle holder and Ø52 mm adapter support different spindles and laser modules, and that it is compatible with Ø69 mm holders.
