    Hi All,

    Im looking at buying a MPCNC kit to use as a laser cutter.

    Looking at high power lasers I came across with this one:

    http://optlasers.com/en/plh3d-6w/175-plh3d-6w-5902693110637.html

    It looks like I can even power it from the PSU that comes with the MPCNC kit, is this assumption correct?

    How does this analog manipulation work?

    It seems to be a very interesting and powerful laser. Might think of making a box for the whole setup with laser filter protection etc.

    Am I going the right way?

    Bye!
    Joao

    They actually contacted me 2 or 3 days ago. hopefully they are working on a write up on how to use there product with the MPCNC. Might want to pop over there and email them to tell them you are interested.

    Cooooooollll

    I was buying the machine from your shop. This is going pretty sweet up to know 😛
    So ill just do what you say and write them an email asking about integration with your machine!

    That’s the same laser I’ll be starting with but not the fancy housing and just ordered a 2W as well for finer detail burning. I got mine from DTR Laser shop. I’ve been developing a mount for it and will do a writeup on the process when I get things together. My thermal paste and parts for tuning the driver came in yesterday so hopefully this weekend!!

    I’m going to be using this driver from Optlasers.com

    Hey David,

    Good stuff! I am only starting with CNC laser 3D print etc.

    I am baby stepping and wanting to do it right. My trade is architecture so I know how to use a scalpel and glue but all this technology is very exciting to me!

    In the past Ive built a couple of guitar amps and other wood/electronics stuff for myself and I manage to do it right!
    BTW you are the Sigil Pickups youtube man right? 😉

    I am about to buy the laser and thank you mr Allted for your linking me with those friendly people from Opt lasers

    They have the aluminium holder attached and when I bought the MPCNC I selected the MK8 extruder mount. Can this mount be of use?
    If the extruder mount is as the one pictured in the second attachment, can the aluminium mount work within the wholes from the Z axis thing?

    I doubt it. The extruder gets clamped in.
    Since the laser takes no load I am sure you can just cable tie it on until you figure out a proper mount. I have done it before.

    Ok

    So I ordered only the laser.

    I’ll now start to see how things go together:

    1 – The PSU is 12v 30A 120/220v so I guess it will be ok for powering everything up

    2 – I would like to run the extruder and the laser from the MPCNC ramps board – an possibly keep both offset mounted at all times

    a – so including one driver slot for the mk8 style extruder (total: 1X; 1Y; 1Z and one 3D print) I think one driver slot will be let free.

    b – Can I use the free driver slot to control and modulate the laser output? seems like often opt laser uses PWM signal for spindle control to achieve this. The signal must variate from 0 to 5v to make it possible to go from 0 to 100% output from the laser.

    3 – I am going to use Fusion 360 from autodesk. Any Ideas, help with this?

    In the end I hope to get all this information compiled and possibly with pictures so that everyone that tries to steer this path has a quick and easy process… Hopefully!

    David are you after this analogue modulation also? You seem to be much more competent that me at this stuff, If you could share your ideas and you setup later on it would be most appreciated.

    ‘night everyone!

    1- It should I am not sure of the laser power requirements. You have 12v30A max 360W, the machine only needs about 12v 3A 36W so as long as it requires less than 320W you should be fine.

    2-keeping both on there will sacrafice speed and precision on both tools, more so on the laser and you probably don’t want your optics near all that dust.

    a-yup

    b-nope

    3-lots of video tutorials on fusion. Not going to work with a laser. Steep learning curve, really steep. You should learn the basics on estlcam first. Fusion has at least 5x’s the options. you really need to know what every single one of them means or you will get bad cuts.

    Yeah, I’m the Sigil Pickups guy…and StuntMonkey Pedals, RaptorFPV, Full Impact MMA, Bowes Digital…. I have a lot of hobbies 😉

    Okay, looks like you’re going to run a 3D printer and laser from the same machine; are you going to do a router as well or just the first two? It’d be possible to do the laser and printer in one but as vicious1 said, it’d be better to run them separately… BUT I understand the appeal to have them both on for ease of switching.

    I’ve been eyeballing Leo69’s offset laser mount and thinking it’d be handy to do exactly what you’re thinking. Here’s the link;
    http://www.thingiverse.com/thing:1301138
    I was going to modify his mounting bracket to fit my heatshink but have decided just to keep things separate for now and use the Hicwic universal mount for each (link http://www.thingiverse.com/thing:1234989). If things go as planned, I’ll probably make a second machine for the laser anyway.

    Also, be sure to follow Leo69’s tutorial on this forum and the main site homepage on how to set up a laser with the PWM/TTL, I’m learning as I go and it’s starting to make sense the more I look at it.

    Advice (like it or not!!): Get your printer running first and then start designing and making parts for the other stuff as you see fit. Once you have the printer running, you’re ready to take over the world!! Then start thinking about tackling the laser.

    Hi Guys,

    Thank you both on your input. I am reviewing all that you said and will come back shorty with more nonsense.

    Lots to review!
