Hello,

I have an Epilog Mini 40 watt machine. It has worked great however recently my clean cut lines have turned into charred burnt lines when cutting mirrored acrylic.
I have attached a couple of reference photos, the mirrored side just looks burnt on the edges.

I have contacted Photo 1-8-19, 12 58 12 pm.jpgPhoto 23-7-19, 10 32 48 am.jpgmy local technician however he has no idea what could be causing this.
