As a new member, let me welcome you and also ask that you please do not multi-post the same question all over thinking you will get faster responses. This makes everyone work harder, in your case…3 times harder.
This post alone with,
this one: Engraving starts, but stops right away - #2 by grindit
and this one: Light Burn configuration problem with Ortur Laser Master 2 - #3 by grindit
We want to help, but not die trying. That said, you do not provide much detail or information that could help us help you. Have a look at this to see what we need to support you with the most reasonable responses in the fastest possible way. Thank you
