If you still need this printed I am in the UK (Dorset) and have a small business that does just this type of thing. Let me know if you still need it doing.
Well having run a focus test I know that my laser is focused currently… I also know that this focus point correlates to the z axis being 17mm up from its lowest position.
If I do not touch the focus knob then I will still be able to focus by ensuring that I am 17mm up from lowest setting when using 4mm plywood. I can then extrapolate to increase this as the wood size changes, so 10mm plywood would need the laser at 17+6mm = 23mm from bottom of the z axis.
The focus knob is more hassle than it’s worth now I have it focussed really well.
Hi, just sen your post - I am in the UK (Wakefield) I would be happy to give this a go, must warn you however that I only recently bought a printer and am still getting to grips with it , in between modding the monkeys out of it. I wanted a new toy to add to my WorkBee CNC and laser.
So if you want I can give it a go but cannot guarantee the results.
You might want to run your existing cone for a longer cut and see how much it heats up. You’d be surprised at how large the beam diameter REALLY is. My metal cone gets hot from the “extra” beam width.
