I need help with firmware update…v1.0.9 to v1.2.1

I recently upgraded my wi-fi and I now have a strong signal at my cnc. I have since connected my cnc to my network . The question I have is my controller has firmware version 1.0.9 and it is asking me to upgrade to 1.2.1, can I upgrade the firmware all at once or do I need to update as the firmware’s came out?

You can leave it on 1.0.9, or click the button to go straight to 1.2.1. You’re call.

Hey Lee,

this upgrade makes sense if you

  1. buy the Z-20 (as it is on the selection list then)
  2. buy the suck it dust boot

Are there any known bugs with the 1.2.1 firmware updates?
