Deal Details
Last time the deal for the Comgrow Robo CNC machine was very popular, now it's available again with the 20% off code ROBO20.

The Robo CNC is quite similar to the 3018 CNC machine kits which several sellers offer.
But it comes with an offline controller, a z-probe, an emergency off, big thumb wheels for moving the axis manually and acrylic sidewalls which contain the sawdust a bit.

It works quite well with wood, acrylic etc. but it's not suited for milling metals.

The kit includes everything you need to start, like the milling bits.
  • Size: 18.1" x 13.8" x 14.6"
  • 11.8" x 7.1" x 1.8" (300mm x 180mm x 45mm)
  • Aluminum frame
  • 10,000RPM DC spindle motor
  • Continuous power 60W, max power 120W
  • Control software GRBL
  • 24V 4A power supply included

I bought this on the last sale. Nice starter machine that will turn in to a small money pit as you strive to improve its abilities. Less than a month and a few more hundred dollars later I wanted a more capable CNC on a larger scale. In hindsight, I wish I'd spent the funds on a 3040 to start with. Not the ones sold on eBay. They're invalid software on defunct circuit boards no longer supported by the maker. Learned that the hard way. The CNC machines validates the adage of you get what you pay for.

Stay away from Comgrow as a company. They sell literal garbage that's either outright broken, missing parts, or damaged beyond repair. In addition, their customer service is non-existent.
