Laser stopping in middle of run

I upgraded my Ortur master 3 laser to a 20w. Everything was working fine , now my laser stops in middle of run, then it will start, then cuts, then stops. Very confused now, don’t know why. Any help would be appreciated.

Whenever a laser module is upgraded there are 2 major considerations for issues:

  1. is your power supply adequately equipped to handle the additional demands of the laser? What is your current solution for providing power?
  2. review cabling for damage and proper connection.
