I purchased these wood pieces from Amazon (https://www.amazon.com/dp/B08QGSBT2N?psc=1&ref=ppx_yo2_dt_b_product_details) and my Snapmaker sometimes cuts through and sometimes doesnt, even after 6 passes at 0.4 with 100% laser power.
Also I tried using blue tape and it barely engraves.
Any suggestions?
I dont use enclosure
Hello in the forum,
If your focus of the laser is ok, reduce the working speed and the passage depth to 0.2 per passage.
Theyâre listed both as âMaterial: birch plywoodâ and â100% solid woodâ. I donât know what you got, but at minimum the seller is sleazy. This is mutually contradictory. Either itâs 100% wood and 0% glue, in which case itâs not plywood, or itâs plywood, which has glue in it, and so itâs not 100% wood. I would return them and make the seller eat the return cost for false advertising, but thatâs me.
Itâs far more likely itâs plywood., since you donât readily get flat pieces of birch without lamination. Itâs a known issue that the laser head is barely powerful enough to cut 1/8" plywood without tuning the machine and good process control. Itâs been discussed here several times before.
The photos in the Amazon listing have no visible surface grain on any of the pieces, which suggests to me that they arenât birch at all (might even be MDF), and the all-caps seller name and weird grammar and vocabulary choices sprinkled through the description suggest a bargain-basement seller from mainland China. Beyond the fact that theyâre probably at least wood-adjacent, I wouldnât bet on anything about these.
Hi friend, did you get a successful auto-focus before you cut the wood? Can you share a video of when the laser module cuts the wood? Thanks
Thanks for the answers.
I ended up using basswood 1.5mm and cuts are indeed better, even the engraving is cleaner.
About the auto focusâŠI have never, since I purchased the machine, gotten a successful auto focus. It always failed and I have manually chosen the best engraved line on the touchscreen.
Does it have to be successful?
