NEWS – Since these early videos were made of SheetCNC Mk1, the machine has been hugely upgraded. The new easy-build SheetCNC Mk3 offers double the speed in  X and Y, and over ten times the speed in Z. The clearance and Z-travel have been increased to allow machining of full 100mm products with room to spare for spoilboard and safety clearance. A new dust collection nozzle helps keep the air clear of fine dust. The Mk3 is equally at home working on 2.5D and 3D products.

Each of the clips is edited to a minute or two and each one shows the finished product at the end. All segments are in real-time throughout: none of the footage is fast-forward.

Early SheetCNC Mk1 cutting 1′ signboard lettering from 12.5mm MDF in one pass.
Feed-rate: 3000mm/minute
Cutter: budget-priced 1-flute 6mm carbide upcut end-mill
This single-flute cutter has very high chip clearance rate and produces a superb finish, allowing deep cuts to be made cleanly in a single pass. The perfect all-round cutter for timber products. Our new dust-collection nozzle is
not fitted in this video.


Early SheetCNC Mk1 cutting 25mm hardwood plywood in one pass.
Feed-rate: 3000mm/minute

Cutter: budget-priced 1-flute 6mm carbide upcut end-mill.
Material: all-hardwood 25mm ply.
The Leonardo bridge in this clip is a rock-solid structure which builds a long unsupported span yet using no glue, screws or nails.
Tip: Cutting hardwood material to this depth in one pass isn’t something we recommend.


Early SheetCNC Mk1 cutting a tiny printed-circuit board.
Feed-rate: 400mm/minute etching; 100mm/minute cutting-out

Cutters: 0.2mm 10° carbide mill; 0.8mm carbide end-mill
We include this one to show the very high level of repeatability which is achieved by a well-designed chain-drive CNC: the 1mm isolations are mechanically etched in perfectly parallel 0.2mm steps, 0.8mm holes are drilled dead-centre on 1.8mm octagonal pads, and crisp text is cut in a tiny 1.9mm font.
An astonishing achievement, for a budget large-format machine.


Early SheetCNC Mk1 shaping multiple complex parts from 26mm MDF.
Feed-rate: 3000mm/minute
Main cutter: economy 2-flute HSS upcut end-mill
There are 8 tool changes required. The automated touch-off probe makes changes quick and easy.
The 2-flute cutters used in this clip are exceptionally quiet. This makes them ideal in a shared workshop. But their chip clearance rates are quite low so deep cuts in thick material are made in multiple steps. There’s no need for a dust shoe when using these cutters: the heavier chippings settle on the workpiece for collection later while the lighter airborne dust is all removed by the very effective extract nozzle.

Feed-rate: 3000mm/minute
Cutter: economy 1-flute 1/8″ carbide upcut end-mill
uPVC cuts cleanly at a wide variety of speeds, up to a maximum of about 6000mm/minute. For this test-piece, a feed-rate of 3000mm/minute avoids any risk of melting and the chippings come away cleanly leaving no burring, even when cutting full-depth in one pass.

Feed-rate: 2000mm/minute
Cutter: economy 1-flute 1/8″ carbide upcut end-mill
A slightly lower feed-rate for this job, to avoid any risk of tearing out the delicate tips of the specially-shaped teeth.

SheetCNC was not originally designed for cutting metals, but we’ve found that the rigidity of the machine is suited to some, very modest, metalworking jobs. We produce instrument panels, brackets, and workshop jigs in non-ferous metals on SheetCNC. We even spot-drill 3mm steel components – though we don’t try to cut them. This is one of our early test-pieces.
