Questions tagged [cnc]

Use this tag for specific question regarding computer numerical control (CNC) machines.

A CNC machine uses a computer controller that reads instructions and drives a machine tool. In effect, all 3D printers are CNC machines, but CNC is commonly referring to machines that are machining tools (e.g. drills, boring tools, lathes).

How do I add auto bed levelling to my Marlin-based CNC?

I just finished a CNC that uses Marlin Firmware. The dimensions of it are quite large (3200 x 2000 mm) and the table is not perfect. I'm thinking of adding a proximity sensor to store a mesh in the eeprom and thus compensate for any errors. I'm not…

3D Printed Lead Screw

I want to build a mini CNC machine and need some lead screws. I was wondering I can simply 3D print some. There are a few 3D models out there but I want to know if printing it in PLA+ has enough strength for a small CNC. Is it possible?
