I am writing regarding my Atomstack S40 Pro laser engraver, which I’ve been using for some time now. Recently, I’ve noticed that the machine no longer cuts cleanly – instead, the material gets burned and the edges are not as sharp as they used to be.
I suspect the issue might be related to the lens, which I have not replaced yet. Could this be the cause of the poor cutting performance? Should the lens be changed after a certain period of use?
Additionally, I’m having trouble loosening the screw on the laser head. I’ve tried using the provided screwdrivers, but unfortunately, I haven’t been able to turn it. Do you have any advice on how to loosen this screw effectively?
I’ve attached some pictures for your reference. I would really appreciate any help or guidance you can provide.
These burn marks look as if the focus height is not set correctly.
It’s not a bad idea to clean the nozzle. Make sure to use the correct, well-fitting Allen key. Otherwise, the grub screw may become worn and stuck.
If this happens, it can still be removed with a screw extractor:
Hi,
In have tried using an Allen key, various drill bits, a screwdriver and even a screw extractor. I managed to get the top metal part to move a little, but unfortunately I still can’t unscrew the screw.
If you have any other ideas on how I can unscrew it, I would be very grateful.
Looks like its stripped out. I’ve had issues with this before. They must use a power tool to tighten it or the have locktite on it. Try using a hair dryer to heat up the surrounding metal a bit then retry. Only other suggestion would be to drill it out a bit then try using the easyout again. Don’t use too large a bit so you don’t mess up the threads. If you are able to get it out replace the screw with a new one.
I also tried heating it with a hair dryer and using a drill, but without success. It’s very small and hard to reach.
The only thing I can still try is epoxy resin — I’ve already tried fast-setting glue, but it didn’t work.
I’d like to share some great news with you… I managed to unscrew this tiny screw with pliers (see picture). I’ve replaced the lens, now I just need to get a new screw and then I can test if the laser works.
Maybe someone knows where I can buy this screw online if I can’t find it in a physical store.
Thanks a lot for any information and for all your help.
Best regards, Franka
