There you go
Youāll have to do a second line once the first line of test is done, and youāll just add another pass on each layer, and so on.
As for the times below each form, I just untick the āsendā button and leave only the concerned shape, and hit the āshow meā (screen icon) button. That way I have the exact timing for each particular value. Youāll have to do this manually for your 2nd line.
Donāt forget to have your test board a bit elevated (mine is 3mm above the workpane) so that the laser can go though easily and some space remains between the bed and the board
That is true but Neje gives a 10k-20k hours of module life. Granted this might be a bit boastful, but most companies donāt even give a lifespan and this is actually a very good clue as to what the moduleās quality is. I think that this particular module is quite sturdy even if you run it always at 100% (which you donāt since you also engrave, not only cut).
But it is better to run at 80% or so, to make it last as long as possible (my guess is that youāll have upgraded to a more efficient module anyway, by then^^)
The heart-tree was cut at 150 mm/min to insure all tiny bits dropped out cleanly and all the rest of the pieces were cut at 200 mm/min. Air-assist was used on all of themā¦
I also found that small 40mm x 40mm x 11mm CPU heatsinks can be used to support the material nicelyā¦ permitting good airflow and easily distributed around to support almost any shape or size workpiece. They are available in packages of 10 heatsinks from several vendors and solve a sometimes nagging problem.
The heat sinks are easy to spread around to support workpieces of various shapes/sizes and I also use a bunch of ceramic magnets to use as spacers/stops and additional support for overhanging sheet.
Thereās a big demand for air assist for the new AtomStack X7 that just came out, and most people donāt have the ability to 3D print. Do you mind if I send them your way when they ask about it? Iām sure $20 would be fair (or whatever you deem) for the 3D printed parts.
I assume you are talking to me since I posted above about my printed air-assist for Neje lasersā¦
I donāt have any AtomStack modules/drawings to get critical dimensioins from. If you can point me to some dimensioned photos/drawings Iāll be happy to take a look but all the photos I see have everything surrounded by a shroud/shield that hides all the module details.
To be honest I think itās the same module, just rebranded as AtomStack. Looks similar but might not be. I see lots of people asking about it and no one has an air assist solution. Maybe they can connect with you and you back and forth. It would go great on an Etsy store.
This is a diode not a tube. I working with neje and other diode laser for years . Most of the time 100% power and adjusted the speed for it, never had any issue or worn out or power lossā¦i use jobs that run 3,5 hours non stop. So no worries it will stand. And for diode better to use mm/min instead of sec.
