Sienci Mill One Kit V2


Shipping to the US and Canada is absolutely free!

Turn your ideas into a reality and create products from materials like wood, plastic, and metal with the Sienci Mill One V2. Whether it’s your first time trying out CNC routing OR you’re looking for a machine to help kick-start manufacturing on your business’ first product, the Mill One V2 is built to be rigid and simple so that you don’t have to be an engineer to use an engineer’s tool.

An 8mm socket wrench, small flat-head screwdriver, and size M3, M5, and M8 Allen keys are needed to assemble this kit. We recommend the Ridgid R24012 or Makita RT0701C routers due their high performance and reliability.

Make a good kit even better! Enhance the Mill One V2’s capabilities by purchasing the anti-backlash nut kit add-on to greatly increase precision for PCB milling and model making.

Safety Warnings and Guidelines

  1. Be sure to carefully follow provided machine assembly instructions before machine use to ensure operator safety.
  2. All wires must be appropriately positioned before beginning the operation of this machine. Cutting a “live” wire may cause exposed metal parts of the routing/trimming tool to become electrified and shock the operator.
  3. Ensure the machine is placed on a flat surface and in a well-ventilated space before operation.
  4. Always wear eye protection during machine operation.
  5. Always wear hearing protection during extended machine operation based on proximity to machine.
  6. Materials may release chemicals that are toxic or unsafe to inhale when cut. Always check the Material Safety Data Sheet (MSDS) of the material in question before cutting. Always cover exposed skin and wear appropriate airway protection (e.g. dust mask/respirator) specific to the  material used and its application.
  7. Any workpiece must be appropriately secured before starting a cutting routine by clamps or other practical securing method. Holding the material by hand or employing any any other unstable form of securing will lead to unsafe loss of machine control.
  8. Cutting bits used for the Mill One should be used at the discretion of the user. Bits are sharp and can crack and break without notice so appropriate care should be taken by the user while manipulating and installing them. Carefully check bits for cracks or damage before operating the machine and replace any cracked or unfit bits immediately.
  9. Carefully inspect any consumable material before use on the machine, any unforeseen inconsistency in material hardness or material quality may cause damage to the machine.
  10. Keep away from all moving parts during machine operation.
  11. Before beginning a cutting job, ensure the router/trimmer runs properly. Immediately disable the tool if visible vibration or wobble occurs. This might indicate a damaged tool or an improperly installed bit.
  12. Make sure the bit is not contacting the workpiece before the router/trimmer tool is turned on.
  13. Do not leave the machine running unattended, the machine should only be operated with the operator present.
  14. Do not touch the cutting bit immediately after use. It may be hot and could burn the operator.
  15. Use bits that are appropriate to the material and cutting speed used.
