3 "p"s to get them stiched the right way - it came out great.
In the meanwhile I modified the moount to accept a 50mm fan - tests pending :-)

Hi Drayson,
I just noticed you asked for my input on this thread but I've been away for a while and couldn't dedicate much time to my laser attachment for the UM.
Now that I have a bit more time however, I'm curious to know how you ended up wiring the laser and your details for the g-code creation to run it.
Hoping to duplicate your efforts and get the laser up my UM Original
Hi Antiklesys!
Great to hear from you - good to have you back here.
In the meantime I figured out how to mount and connect the laser as well as a (more or less) useable toolchain.
@ mount: I designed two brackets to simply snap it below the print head. For zeroing Z I simply made a spacer with app. 160mm to get the platform in the right distance.
@ connection: I soldered a pinheads at EXP3, GND and Pin 13 to the UMO board and used a simple relais for switching the laser on and off - unfortunately 100% on or 0% off, so no power control... The pin is adresses via a M42 P13 Sxxx command - S0 for off, S255 for on.
@ toolchain: I got Cut2D running and managed to get the postprocessor doing the "right" things to get the UMO up and laser cutting. Good thing at Cut2D: simple and intuitive, bad thing: no "lines" cuttable, it has to be something like an "area". I set up different tools to addess different materials/speeds - here I´m still in tweaking and testing. Further I worte a little gcode to prepare the UMO for laser cutting (zero, then down 180mm to allow spacer input, then zero again, move to mid/front to snap on the laser head).
So, this was a lot of writing :-)
Hope it helps you a bit - otherwhise just ask :-)
Amazing stuff drayson. Do you have an approximate cost for this setup? And any closer to releasing a parts list? Are you going to attempt to cut thicker materials?
I'll keep an eye on this
I'd love to have a laser tool head for the new printer. And smoothieware already has a working laser module.

I'm currently in the process of trying to figure out what I was doing at the time I was messing up with the laser and document it, so I know where to continue from
Would love to follow up on Skype tho or whatsapp if you fancy. PM me
Hi all!
Great to have such a feedback :-)
@ Macao
The 3W-laser costs app. 85USD, without shipping (a friend took it over to Europe), the electonic components a few €, the box app. 6€ and the alu, wiring, etc. also a few €.
I would estimate roughly app. 150 - 200€
Currently, the thickest material I cut was a 2mm architectual cardboard (ok, and I managed to change a 4mm balsa piece into a 4mm carcoal with a hole in it..).
I have to test a bit more, but currently it´s setup only for paper/cardboard cutting. (b.t.w.: I found this list of material/cutting data from emblaser: https://docs.google.com/spreadsheets/d/1Z5cy-z8XW8XLOGNaC4WRI_AFFluJn5Tk5GJi0e3ocxQ/edit?pli=1#gid=0 As they use also a 3W laser it might be usefull. honestly, I used their design for inspiration too...)
@ foehnsturm
great to have you in too - hope everything is fine in München :-)
I only found a description how to use the smoothieware for building a cnc/laser mechanics, but I have not found a module at their page... anyway, I learned that it is hard to get a 3W module in Europe... :-(
@ antikles
sure, I´ll PM you my skype contact.
I will also try to revers engineer the things I changed during assambly and post them - also the stl's for the printed parts. unfortunately I´m a bit burried in work at the office, but I promise to make the design available...
Can anyone read Chinese here?! I found this on taobao, no idea what the specs are though. However I thought the laser on a lead was an interesting feature, would make mounting one super easy: https://item.taobao.com/item.htm?spm=2013.1.20141002.3.MQAJmZ&scm=1007.10009.12973.100200300000004&id=521044932399&pvid=e818590a-e77f-4224-af08-56f6844349ce
Sorry, it seems this page is not available.
I would recommend to buy the laser at DTR's Laser Shop (that´s the Laser I bought https://sites.google.com/site/dtrlpf/home/diodes/9mm-445nm)
Maybe it´s my personal attitude, but for this risky stuff I would use a trusted source...

With this kind of equipment I couldn't agree more !
Edited by GuestCurrently I redesign the "shield" which is placed between the laser itself and the cutting plate. It's more or less a tube which prevents to look at the beam and also assists in air directing but unfortunately I´m terribly sunk in work in office so progress is verrrrry limited...
I will start uploading the printable parts which are finalized up to now to youmagine soon. Schematics I have to update as there were a few "hands on" changes, but they will follow too...
I'm looking forward it !
Hi all,
finally I got all the tings together and put them on youmagine
Her you´ll find my design for the clip-on laser head and the electronics.
Disclaimer: build on your own risk - I´m not responsible for any damage at you, your stuff or your wife :-)
Thank you Drayson for sharing your hard work, I'm going to give this a try within a couple of weeks !
Just got my laser up and running today. Quite fun

Cool! where did you get it? can you share a bit more on the installation?
GREAT WORK !!! Congratulation!
Which SW have you used for gcode generation?
But... please do me a favor and add some protection. would be a shame if somehing happens with your or somebody else eyes...
Edited by GuestI got it from J Tech Photonics
I got the Kitset that comes with driver, laser and glasses.
Its a bit expensive especially for me with shipping and customs charges, but I have Had a lot of 3D hubs jobs lately that payed for it.
I turned up the heat-sink myself and printed the holder. Its using a 30x30mm 5v sunon cooling fan connected to the hotend rear fan. Although the driver has fan output.
The driver is easy to connect and has instructions on how to connect it to UM2 and UM0.
I used the Fan output to control the laser and it has PWM to be able to adjust the laser power via gcode fan percentage.
Im using Inkscape which J Tech provides instruction on how to use it and there is a Gcode plugin to convert images to gcode. I just added some code for the startup and finish.
I live alone so only have my eyes to worry about for now and I always use the glasses that came with the kit. But yes I ill be incorporating something a bit better latter on.
This is the first time I see someone offering a laser kit which looks very well thought out.
My mayor customer is developing various "small" laser marking, cutting and welding systems. So I asked a person there about an opinion on it.
Well done!
I was not aware that JTech now offers such a professional stuff :-)
I got the idea for hooking up a laser to my printer basically from him, but also merged some input from L-Cheop, EmbLaser and others into my solution - but the PWM controll is VERY nice so it´s worth thinking of an order...
@Labern great stuff
Is is possible to cut stuff with it too?
Yes, when I get time I will post some cuttings
it cuts plywood?
Me want a laser cutter ^^
