Sienci Labs made headlines a couple years ago when they successfully funded and launched their Mill One benchtop CNC router on Kickstarter. It has proven to be a popular option for makers because it offers solid performance and a very reasonable price. The only downside is that is has a small build volume — just 10.15 x 7.25 x 3 inches. Many makers and woodworkers want to be able to work with larger material, which is why Sienci Labs is launching the all-new LongMill benchtop CNC router.
The Sienci Labs LongMill CNC router just launched on Kickstarter, but has already exceeded its funding goal. That’s because it shares the most important attributes of the Mill One: performance and value. But make no mistake, the LongMill is a completely new design and not just a larger version of the Mill One. The LongMill is available in three sizes to suit your needs: 12 x 12 inch, 12 x 30 inch, and 30 x 30 inch. Though the largest model still isn’t big enough to handle a full sheet of plywood — or even a quarter sheet — it is large enough for most maker projects.
That size means the LongMill needs a robust linear rail system in order to remain rigid. That’s accomplished with 1/4 inch steel gantries on all axes, large extruded aluminum rails, high-precision MG-12 linear guides on the Z axis, and T8 lead screws with anti-backlash Delrin nuts. Thanks to that strong frame and the beefy stepper motors, the LongMill is capable of cutting at speeds up to 3,000 mm/min and has a resolution of just +/- 0.1 mm. LongMill will work with all popular CAM (Computer-Aided Manufacturing) software, including Sienci Labs’ own free CAMLab.
If you want a LongMill, the Kickstarter campaign will be running until April 25th. Early birds can get the 12 x 12 model for CA $950 (about $709 USD), though you will need to supply your own handheld router. Rewards are expected to be delivered in July.
