Ortur got back to me about my inquiry as to the OLM3 (400x400) + 20w + 1.6w + platform + air assist. 24v
They say they dont have the 1.6w So I asked about IR6410 or 5w from them or other manufacturer that would suit with no mod’s needed.
I thought I’d ask here because I fear another long list of questions with vague answers.
would the 10w at 0.05x0.1 advertised spot be ok to start learning fine detail engraving?..its a budget thing! but may OPT for an upgrade asap.
Does anyone know if the OLM3 is 8bit or 32bit…I had assumed 32 but came across an advert for 32bit upgrade board & I cant find the info on their site…One less upgrade to get me dialed in for detail.
Amazon list the shipping + tax to Ireland as over 300 euro. Would I buy equal quality in europe and avoid the import tax.

You sure about these numbers? That is a 1:2 x:y ratio. It means the Y kerf will be twice as wide as the X kerf. Typical advertised for diode lasers is .06x.08, which is a lot closer to square. Of course, it depends on your definition of “fine detail engraving”.
Firstly, sorry for hours not answering, my buddy had a little send of for his son going to college in engerland…had to attend.
Thanks Mike, I hadn’t consciously related x to 0.05 & y related to 0.1…now I do!
The 1:2 didnt seem that outa whack at the time given the fog of purchasing and that its pretty small relative to some of the long recktangles on the market…maybe if I did the 45deg adjust it might not be to bad.
The 20w is for cutting and a bit of speed and bigger engraving, at 0.08x0.08 as (advertised) seems reasonable for that type of work and possibly more squarish.
I like to blend the detail into the bigger work…thinking about the 8ft x 4ft bed which lauches any day now…it might sound odd but I see potential.
I might be better off just playing with the 20w and getting used to things and look into something a bit custom asap.
Its more moving toward fine fine detail that Im looking at right now because its a different level and market.
Yeah…If & when. its the Tyvok S1, 60w/40w/20w…runs on rack and pinion y axis. I think they may do a 4x4 but not sure.
I dont do social media so Im out of the info loop thus far until the launch.
Ah cool, I spent a week or so looking at those and quite liked them, also warehoused in europe which is handy.
I think I was tempted away by the k1 frame being 40x40mm to carry a k30w and a 5w from lasertree…but 23 emails in and still not much wiser, I went to have a chat with ortur…I was as far as asking LT for bank account details for transfer but heard no more from them…I think it was voltage and maybee board incompatibilitys that they didnt want to talk about. Im kinda insistant about knocking the most out of one strong frame…that might be my problem but double the frames is half the quality in my mind.
Would 300um (0.3mm) be considered as a good starting point…To start working toward fine detail.
Just made an enquiry to OPT for info about dot x/y measurement and module weight concerning their 6w for Ortur OLM3. (cant give link because no access to saved pages, from this page).
The Ortur LU 20A is 0.08x0.08(advertised) but the import tax eats up a wee chunk of the funds for the opt6w…if its Square!
Found this on the web:-
The pictures tell a lot about dot dimm’s but I wonder was there something else mechanical going on at abou the 4 o’clock area in the right hand picture.
Is this a good example of the difference between Co2 & diode?
Remove the module from the gantry. Set the power at about 10% and point it at a wall about 6’-10’ away. You will then see the true pattern of the laser beam shape. It is definately not a dot or oval.
Not for a 20w laser, which is where they try to focus 4 diodes to 1 spot. In my opinion, they understated the size.
That must be where the special lens’s come into play.
I asked Lasertree about replacing the stock diode with one of their parts list individual 130 dollar +/-, 5w diodes but they said the improvement would meaningless…that might have been where they upsold me a lens, but they dont seem to take the initiative, they also had a panasonic at aprox 1000dollars…I didnt go there.
We’ll see what OPT have to say…be nice to be able to swap modules…quickly!
Only a guess, but I suspect the lense to be as important.
The K1 40mm x 40mm alloy frame seemed good at…was it 400mm x 600mm.
Ortur are also doing a cheap 300mm x 300mm that sits all sides flat on the table “glued it all round” & If the gantry was capable of taking the weight it would be a good foundation for high spec module for fine detail.
A custom lens could help. It would have to have a custom shape, which means orientation at installation would be critical. If you can find one of these lenses, let me know.
