Download Micrometer CNC 4 Raspberry Pi3 [SHA1 | SHA512 | GPG_sig] (3.7GB archive expands to fill 32GB sdcard)

If using the disk-image install methods, we recommend a new class 10 32GB Sandisk micro-SDCard with every annual release.

  • Some Flash memory technology starts to get unreliable after about 1 year of daily use
  • You will have a full OS backup to keep your machine running if something goes wrong in the update

If you did not alter the OS setup text files on the Card before the first boot, than the defaults are:
