Wanted to see what the IR would do on a glaze closer to its own frequency. I was not ready for the result. At 6000mm/min, 100% power… the IR passes right through the glaze and etches the ceramic.
Here’s a bit of a few finger swipes so you can see the glossy top glaze is untouched and the engrave is under the surface.
How curious.
I think that look’s pretty cool, very subtle. First thing I thought was, serving plate…side dish…logo stuff.
Is that an 3x8 tile, did it take long.
3x6 tile, didn’t take too long.
Are you using the Ray enclosure for any heavy cutting & does it perform as expected.
How has the 40/20 worked out compared to 20w or 10w in terms of travel/speed and accuracy, if you have them.
I saw the 40w v IR pictures of coin engrave & although it seemed like a mismatch challenge I thought the 40w did a fairly good job…all thing’s considered.
Sorry for all the?'s but do you know the ultimate height of the module from the worktop level (without base protector), The measurement of the underside of Y to the workTable & is the air assist tube well controlled as the head moves around.
Just some factors I haven’t been able to pin down.
I’m sorry I didn’t specify the machine I have. I’m using a 2.0 A350T. I have the 1.6W, 10W, 40W, and IR modules. I haven’t done too much with the 40W so far, mostly using it for a cutting beast. (13mm plywood in one pass).
On stainless steel, the 40W is fine from what I’ve seen, again I haven’t done those tests personally.
As far as the enclosure, while I do have an inline booster fan, it’s done fairly well, the air assist on the 2.0 is velcro’d to the power cable, so it’s out of the way as well.
Which laser are you asking about the size of the module? The IR or the 40W?
Well Im most curious about the 40w, with the bit of learnin Ive picked up over the last few weeks it seems like a velocity v accuracy tradeoff & finding the sweet-spot with quality v time.
1.26kg kinda made me nervous although I do see the potential…and as said the coin test in comparison was great…but what got my imagination going was the better ‘thin cutting’ -/+ 10mm and quick engravings…Im not a speed freak! but I will recognise the need for time efficiency when it matters.
I like the SM way of going about things and have been hard studying machines for +/- three months to find what I want and SM ticked a lot of box’s so the ray arrives next Wednesday from Germany with 20w and IR.
I wasnt sure about the 40 and can run the learning curve with those two and try the 40 when it makes sense.
The biggest thing on speed vs quality is getting the backlash offset right. With the 40W you do have the benefit of not just lowering the power, but you can actually turn off half the diodes. Effectively making it the 20W, but also with less lasers to try collumating, you get a finer dot. So you basically have those two ‘modes’. Full diode or 40W for speed, cutting, etc. and half diode or 20W for lower power and finer details. Basically two in one.
On my 2.0 I’ve ran it at speeds upward of 6000mm/min, and it’s been fine. I’ll try to make myself swap in the 40W (I have the IR mounted) and see what quality I can manage from cranking speed and power up.
Right! thats why the tile didnt take long.
Yea whiplash, but speed wobble on fine lines was another worry I had even with 30x30mm frame, and thought slower might work for that…but would the 82g 20w be the sweetspot. I kinda want the tyvok 8x4ft with rack n gear and that uses 20-60w for big work…but its still on kickstart and they have way too many typos in their data!
You won’t get the wobble like belt driven lasers. The modules are mounted and run on full solid leadscrews. Which brings up backlash, but that can be compensated for in software.
True! & I just like it all round for various reasons…didnt go for the enclosure though. I think I’ll have a crack at a self build, I’d love to do the sensible thing as Im no cabinet maker but I’ll give it a go.
Must lights out…were well into the am hours here…Good luck with the 40w!
