I've just bought an 800w G-Penny spindle, and after some advice on the initial running-in process - as there is conflicting information online.

  • The widely accepted minimum recommended frequency for the air cooled spindles is 120Hz (7,200rpm).
  • The description on the AliExpress listing says to run in progressively from 3,000rpm.
  • I messaged the seller and they said start from 100Hz (6,000rpm).

Am inclined to follow the sellers advice, but hoping for some real world experience to start me off on the right path! Thanks in advance..
