I get excited every time I see your videos, the content is very good, I hope you can make more videos

[@NEWTechCreative]

Thank you! Great to see the new Ortur H20 machines coming out 👍👍

@@NEWTechCreative If you like this machine, we can always send you one for testing.

[@orturrich5281]

@@NEWTechCreative Do you have more ideas about laser engraving machines now? I can't wait to communicate with you.

[@NEWTechCreative]

Thanks for your kind offer!

[@RootCNC]

Love it! I want to see a plasma cutter made from it ;)

[@NEWTechCreative]

Thanks Pete!! That is very tempting 🤩🤩

[@PiefacePete46]

Great bones for a large-format CNC drag-knife!

[@NEWTechCreative]

Absolutely! I did have that in mind 🤩

[@Anx2k]

Great build! What extrusion is that? I've never seen the U profile, and couldn't find it on the usual suspects like 8020 or Misumi... I'm assuming you chose it as it would be less susceptible to flex, and you could nest the cables back in it a bit?

[@NEWTechCreative]

Yes this type of extrusion is called a v-slot 4080 cbeam. I had it left over from other projects, although it is overkill for this project. On the other hand, I didn’t have any flex issues! I thought it would be interesting to integrate the belt within the frame to provide more usable travel area!

[@John-gw3mj]

Please reduce the volume on your intro music a little next time, I nearly clicked off the video immediately.

[@NEWTechCreative]

Thanks for your feedback!

[@ThomasTomiczek]

Yep super unprofessional..... the video is way lower in volume than the screaming intro music.

[@1dodgyjammer]

Maybe synchromesh cable is a better solution than belts to eliminate some issues going around the pullies and tensioning. Great project!

[@NEWTechCreative]

Very interesting! I will have to look into this. Thank you 🙏

[@RNMSC]

One thing to add to the suction cup system would be a way to rotate the object being held, perhaps with a servo for rotation around the vertical axis, and a rotation around x or y axis, then add a camera that finds a reference mark on the ball and orienting the ball as it moves it, possibly with interim pauses to find the mark with the camera, and to deal with the fact that one or both of those axis is likely to not be 360 degrees of rotation. One of the things the code would have to work out is 'if it can see the mark to begin with, or once it's oriented the mark, if the Z axis of the ball is not the z-axis of the effector, how far along the off axis does the effector need to be moved to put the ball in the proper holder? I.e. sin of the angle of rotation times the resolution of the x/y effector change. Out of this may come the ability to use brushes or ink well nibs to do calligraphy with those pens down the road, as that is likely to require keeping track of the angle and writing direction of the pen. Most of the inkwell pen nibs require "drawing" as in 'pulling' the pen that is not oriented vertically, however loading the pen may work best vertically. And yes, working out detection of when to reload the pan gets interesting as well. Possibly training the system using a disposable fountain pen then moving up to an inkwell pen system would be a good process.

[@NEWTechCreative]

Dude! Thank you for your comment! Love the your thinking, direction and ideas. I was working on a small program a while back that could easily adapt a rotational axis mainly for drag knife or concrete extrusion machine and this would be perfect for what you’re suggesting. Essentially the program uses the current and future locations to calculate angle of z axis before moving and adds extra gcode as needed. This is a nice rabbit hole to go down for fun 🤩 Thanks for your support and ideas 💡

[@rpals5412]

very cool! ⭐ What kind of price are we looking at, all of the parts and built materials combined at this point ? Asking because I have wanted to built something similar but different for a while.

[@NEWTechCreative]

Thanks for your comment! I have roughly calculated to come to a maximum of $750USD. This includes everything such as hardware and electronics, however only with plastic 3D printed parts. An additional cost for machined metal parts!

[@rpals5412]

@@NEWTechCreative Thanks! That's a bargain tbh - Well done! looking forward to see updates :)

[@maximevilladary]

amazing :o You don't have any calibration ?

[@tken93]

Jesus could you make the intro music a little louder? I don't think my speakers were fully blown yet!

Sure thing!

[@tken93]

@NEWTechCreative appreciate it dude! Haha 😂 good video btw

[@deltacx1059]

10:56 and what might that price be? I'm curious I am building a large core xy as well

[@kurtnelle]

I too am making a large corexy and would like to know what counts as affordable.

[@deltacx1059]

@kurtnelle I went and put my parts into PCB way after making that comment, so for printed aluminum like his mine cost about 70 USD according to the auto quote for two carriages which honestly seemed a little steep considering they are basically c channel but if you pick ABS the price tanks to less than 20 USD.

[@NEWTechCreative]

When manufacturing one off parts, no matter the process of can seem expensive, however compared to what it would cost traditionally for a one off item, they are incredibly reasonable! You might be able to get away with 3d printing the parts if you have access to a printer 🤩🤩

[@deltacx1059]

@NEWTechCreative yes that is true.

[@ElizabethGreene]

Howdy! For future notes, including triple X in the title of a video or the name of a product will cause pain for people behind stupid content filters. It shouldn't, but software is dumb, and people that implement that kind of software are dumb, but it's a problem.

[@NEWTechCreative]

Great point! I didn’t even consider this. Thank you for bringing to my attention 👍

[@3DDrukSuiderland]

Probably won't work, but just at thought. What about putting magnets, like fridge magnets, not supper strong, on the wall behind the belt, see if the metal in the belt stays closer to the wall to prevent the belt drooping / moving out of place.

[@NEWTechCreative]

Awesome idea! I never had thought of that. This would be a great way to support belt if it has enough attraction. I might try I out. Thanks for this 👍👍

[@BarioIDL]

corexy printer is 350 at best, you should use rack and pinion

[@SaHaRaSquad]

500mm corexy printers have been a thing for years and at least one upcoming model has 600mm.

[@PorkChopForLifeMC]

this is just not true... there are a lot bigger printers than 350x350mm... and rack and pinion? thats super expensive and heavy... not really needed for light weight machines like this

[@NEWTechCreative]

Good point! The only issue with rack and pinion is it adds to the weight of moving axis.. however far more effective with precision 👍👍

[@BarioIDL]

@@SaHaRaSquad keyword: at best there's a reason tronxy500 is not popular, it's too slow for its size

[@BarioIDL]

@@PorkChopForLifeMC "light weight" have you considered... 3d printing the rack? you can even make it herringbone

[@googleyoutubechannel8554]

This is neat, but y'all 'corexy' speed people.. you do know about all the plotters from the 60-80s right? They... already did this... much faster... you're sort of reinventing old tech.... just with better micro-controllers... but poorly... eg kzbin.info/www/bejne/j329pYaLnqdlm6c

[@KilianGosewisch]

first of all. no the plotters were not much faster. second, our toolheads are much move heavy. plotters also were no corexy machines, they are analog to what we call bed slingers.

[@NEWTechCreative]

This is very true! Nothing like reinventing the wheel 🤩🤩

[@jamieclarke321]

Yea accelerating a piece of paper isn’t comparable to accelerating a print bed. Also the same applies for a pen vs a tool head

[@declanb6985]

Right?! We need to stop tinkering and making because there are or were commercially available options 40 years ago! It's about the adventure and the results are modular platforms that can be built to do a great number of things. That didn't stop me clicking on your link to see what I could learn from the OG's, though. :)
