I, too, have a little Eleksmaker A3 machine with 2.3W laser module and I have been very happy with it when doing NWT ceramic tiles…
Not yet Nicky Norton quality… but passable IMO and fun to do. Haven’t been able to do nearly as well with any of my other lasers, diode or CO2.
Also, just discovered this today in another LB thread… same machine and laser module.
Having fun again rediscovering what that little laser can do…
