What are some CNC Router Optimization Techniques – Tips and Tricks for Efficient Workflows

Software / Firmware

Hi Everyone,

I’m new to the world of CNC routers and have recently started working with a 1300x2500 router from a local manufacturer in India. My current focus is primarily on 2D work, with approximately 95% 2D tasks and 5% 3D work.

I’m looking to improve efficiency and reduce working time on my files. While I understand that each project may require its own specific optimizations, I’d love to hear from experts about some general tips and tricks to optimize machine performance.

Here are some of the techniques I’ve come across:

  1. Selecting the right tools, feed, and plunge speed for each task
  2. Reducing the number of vector nodes
  3. Increasing stepdown while lowering feed rate to minimize cutting passes
  4. Proper grouping/ungrouping of vectors to reduce Z-axis movements

However, I would like to hear more from the community about your personal optimization strategies for tasks like 2D profile cutting, 2D area cleaning, and 3D/2.5D work.

Your insights will definitely help not only me but also others who are looking to streamline their CNC router processes. Thank you in advance for your valuable responses!

Hi, if you are new to the cnc world, just start by reading the milling basics in the documentation. There is NO SHORTCUT PATH to a successful cnc job and safety. The docs are intended to use our diy machines so if you have a commercial cnc on your hands you should research about the controller/mach3 that it is probably using as we don’t use such programs. Also take notes: the speeds and feeds will vary mostly because an industrial cnc can achieve much much greater depth of cut& speeds based on rigidity, spindle power etc.

Proper layout of multiple pieces (nesting), and manually setting the milling order (rather than having EstlCAM do it automatically) are two things that come to mind.

For machining order, I specify the screw holes first, then place a Pause command in the G-Code between the screw holes and any subsequent Parts/Holes operations. During the Pause, I insert screws into the screw holes for holding the parts to the spoil board, instead of using holding tabs.
