Moving up from a 3018: what the next machine adds on paper

The 3018-PROVer V2 against every machine in the record up to $1,500: how much more work area, Z, drive and spindle you get.

The 3018 is the machine a lot of people start on: small, cheap and enough to learn the whole design-to-cut process. When it starts to feel small, the question is what the next machine actually adds. This guide compares the SainSmart 3018-PROVer V2, as SainSmart lists it, with every machine in the record that publishes its work area and costs $1,500 or less. Nothing here has been tested for this site; it's what the spec pages say.

The 3018-PROVer V2's work area (smallest) against SainSmart's larger machines in the record, at the same scale. Original drawing.

Where you're starting from

SainSmart lists the 3018-PROVer V2 at $219.00 with a work area of 290 × 180 mm and 40 mm of Z. Its page says it uses a "leadscrew" and a 775 spindle, and doesn't give the spindle's power. Those are the figures everything below is measured against.

Staying with SainSmart

SainSmart sells six larger machines in the record at $1,500 or less:

Other makers, up to $1,500

Machine	Price	Work area	Area vs 3018	Extra Z	Drive	Spindle incl.	Spindle power
FoxAlien Masuter Pro	$600	400 × 400 mm	3.1×	+20 mm	Not published	Yes	Not published
Two Trees TTC450 Pro (500W)	$628	460 × 460 mm	4.1×	+40 mm	Not published	Yes	500W

FoxAlien Masuter Pro Max 2x2	$900	600 × 600 mm	6.9×	Not published	Not published	Yes	500W
Onefinity Apprentice	$995	419 × 419 mm	3.4×	+93 mm	Ballscrew	No	Not published
MillRight CNC Carve King 2	$999	438 × 438 mm	3.7×	+62 mm	Leadscrew	No	Not published
FoxAlien Masuter 3S	$1,000	400 × 400 mm	3.1×	+55 mm	Not published	Yes	400W
Makera Z1	$1,249	200 × 200 mm	0.8×	+60 mm	Leadscrew	Yes	150W
FoxAlien XE-PRO	$1,400	400 × 400 mm	3.1×	+55 mm	Ballscrew	Not published	400W
Sienci Labs LongMill MK3 30x30	$1,400	813 × 813 mm	12.7×	+77 mm	Leadscrew	No	Not published

"Area vs 3018" is X × Y work area divided by the 3018-PROVer V2's, and "Extra Z" is the difference in published Z. Both are my calculations from the makers' figures.

What changes on paper

Size. Every machine above has more X × Y than the 3018, from 0.8× to 12.7× the area.
Drive. Three of the sixteen list ballscrews on every axis: Onefinity Apprentice, SainSmart PROVerXL 4030 V2 and FoxAlien XE-PRO. The rest use leadscrews or don't say. What the difference is.
Motors. Four list closed-loop motors: FoxAlien Masuter 3S, SainSmart PROVerXL 4030 V2, FoxAlien XE-PRO and Sienci Labs LongMill MK3 30x30. Open and closed loop.
Spindle. eleven include a router or spindle; three don't, so their price isn't the price of a working machine. The cost estimate adds a sourced router where one exists.
Space. A bigger work area needs a bigger bench. Check the footprint with the bench visualizer before buying.

What this guide doesn't cover

Upgrading parts of a 3018 instead of replacing it, and how any of these machines perform in use. The record holds complete machines as their makers describe them.
