Hey, Does somebody know what is in the green pipe going to the Laser head? (you can see it well in the Intro at 00:07 ) I didnt understand if the laserhead needs cooling or whether it is for gas injection. If gas: which kind of gas did he use? I'm sorry if its somewhere mentioned in the series but i didn't find it. Thanks a lot :D
Hey Chen, its just compressed air to 1. keep any smoke/dust getting to the focuslense and 2. it helps cutting and keeping the material free from burnmarks. 😉
Great build! Are you going to mount a leadscrew plus stepper in each corner? How are you going to keep them synchronized? In the first video you mentioned that you're not going to use a single stepper and a closed loop belt to drive the other corners.
Thanks Thunderbelch, Yes I've mounted a stepper plus leadscrew in each corner which works very well. I tried 2 prior solutions which didn't suffice imo, where I wanted to use only one stepper and a closed loop belt, but I didn't find any in that length, donno exactly but it was more than 2200mm... So I thought of using a chain but got this idea and found it easier and faster to do ;) I run all 4 steppers in parallel over the same driver which works, I have No Control if it's synchronized, but I have fine tuned them so that they don't stall anymore and haven't done it since... I explain some of the laserbed stuff in Part 4 were I show how I semi-synchronize them :D
Cool. I saw that video since commenting and it makes sense. Running them to the limit (stall for now; limit switches x4 later) to sync them makes sense. On my 3D printer I found that each time you power down the machine there's a chance the motors might get out of sync as one slips half a step up and the other half a step down. Your syncing on startup should take care of that nicely...
+Thunderbelch Well actually I don't sync on startup and maybe do the synchronizing twice a month manually, so now you mention it yes they do tend to fall to a full step so it would maybe be a good idea todo it more often. Thanks, it never crossed my mind
It's fun to watching what you are doing there. Could you do upload a video on Sketchup details? Or introduce a session I can refer on aluminium profile?
Thanks Kim, I'm afraid the sketchup plans are not complete, but you can download them from the description from one of my videos as others have asked. For the aluminium profiles I used standard 20x20 and 20x40 Nut 6. I bought mine from motedis.com, good prices.
glad to see im not the only one using my Dremel if there isnt enought room for my drill :p really awesome! video. i could never do what you just did lol
Thank you Patrick, hehe Yes, but I don't use the dremel as often as I should though ;) oh and never say never, cause 5years ago, I'd never imagined myself doing this either, but I just jump into it with the cnc back then... and seriously, it isin't rocket science, actually not that much to it, when I look back at it, expensive learning from my part :) some researching is required though :D
+Sergey Grigorenko Thanks man, I haven't used them for anything yet, they are linear but not butter smooth, they definitely have some resistance to them and make some noise when moving fast so it depends on then speed I guess 😉
Well I had a cnc, but cutting plexiglas/acrylic was a big pain in my behind. So laser was the shit... So alot of research and just whent for it basically... Not much planning, just started building something 👍
Hi gEEk0021, thanks for asking, I guess Lego's and building was always my thing so I have a Bachelor of Science in Computing, and work as a Software Developer at an Industrial automation company. I guess I get enough of software during work, that I just wanted to build stuff in the free time ;) hence the urge to make stuff :) Not that I'm good at it, but I sure try and will make it work somehow :D

Awesome. Are you structure design files available?
Thanks Sean, I'm afraid I don't have anything useful except a half finished sketchup model 😑

Are the files available for the Nema motor mounts you used below the table top?
I'm believe not. I drew and generated the gcode with Cambam so if you have cambam?, then I can check
@@InventorsFactory Yes I do have Cambam. If you can check I would appreciate it. Thanks
@@InventorsFactory Thanks so much I really appreciate it!!
Great video! Did those rails from aliexpress turned out ok? I want to use them for my 3d printer.
+Sergey Grigorenko Thanks man, I haven't used them for anything yet, they are linear but not butter smooth, they definitely have some resistance to them and make some noise when moving fast so it depends on then speed I guess 😉
wHERE DID YOU GET THE INSPIRATION TO BUILD THIS?
Well I had a cnc, but cutting plexiglas/acrylic was a big pain in my behind. So laser was the shit... So alot of research and just whent for it basically... Not much planning, just started building something 👍
Super...
What is your background and education?

Dude ur r awsome
Thanks man, lol
