If anyone is a pro with lasers (specifically xTool D1 Pro), please comment tips. I need help with stainless steel engraving. I have a big order and little time. I am struggling big time with this thing.

Basically it prints 1/8 of the design then just stops. Different errors pop up, I have tried all troubleshooting suggested on the website and at my wits end. Sometimes it’s about the card. Sometimes it says laser disconnected. But I cannot complete a single project. Stops at different place each time. Trying to engrave dogs tags. Stainless steel. Power 100. Speed 25.
