I laser engraved a greyscale image yesterday, and although it turned out a bit dark, it engraved exactly as I expected it to. When I try to engrave the same image on a different piece of wood with a slightly greater brightness value during image processing, the laser is firing but there is nothing being engraved. I’ve tried dialing up the laser power and the dwell time per dot, neither change had any effect. I get a blank piece of plywood despite hearing and seeing the laser firing. What should I change or tweak to get an engraved image?
This is on a brand new A350 with the 1600mW laser module.
Not sure if this is something to express here, but I have been a Snapmaker 2.0 owner for about two weeks or so now. All of what i have been doing so far is Laser Engraving on wood. I started out using cardboard as I didn’t have any wood around to engrave on. Since I started, I have found some nice wood to use on Amazon. What I have tried to master is engraving Grey Scale images on the wood I have purchased. What I have determined, through trial and error, my grey scale images are of so much better quality if I export the G-Code to a USB Drive, then plug that into the SnapMaker machine rather than send it via the file via WIFI. The difference is like night and day. Not sure if it is my WIFI connection to the machine or I have wondered about the BAUD rate that is used sending the file, but using the USB Drive to engrave the grey scale images is the only way I do the engravings now. Something for yous guys trying to engrave grey scale images with results you are not happy with might want to try.
