Yup, this is FreeCAD.

I am glad you like the explanation. Thank you for your comment. Keep building!

CAM software within FreeCAD called Workbench.

@@curiosity-creates I too use FreeCAD, in fact I made a post processor for the Masso controller.

I had 2 reasons for that: 1) to reduce the distance between the two active pulleys, 2) to increase the engagement of the belt with the teeth of the smaller pully by making the belt wrap around the pulley a bit more. But in the next iteration of the actuator that I use in my video about the 6-axis robot, I have gotten rid of the idler and used a smaller timing belt. The actuator works great with this change too.

The design of the machine has received some decent constructive criticism, but your comment takes the award for being the most non-constructive comment. So, very nicely done to you too!

@@curiosity-creates my comment was purely sarcastic. Desktop scale? get a 6040 and machine steel with it.. it will do it if speed&feeds are right. will it look mirrorlike as with an kern, certainly not. also +- 0.1 is not precise, so not a real goal here. You target a cheap solution but go for Linear rails? Supported rails or even drawer slides are way cheaper and can be used also if you need to go really cheap i could give a few helpful tips if you like tho. as others mentioned, you need to put your guides as far apart as possible also the same with the carriages. you stack plates and use epoxy granite to fill these, which is great! Maximize the distance between the Y- Rails with using them 180 degrees rotated from each other, then you also can mount the plates on that directly. speaking of gantry plates: it might work like you did, but a more solid aproach with less of a 'z-bend' shape, also filled with epoxy granite should be way more stable. If you want to go for maximum stiffness, a moving gantry is not the way to go. You lose on y axis space tho, as you need more space to have the same travel. A fixed gantry could be made much more rigid due to not having to be moved.

😂 gayt damn

Thank you for your comment and suggestions.

Biggest is he's using one berring block for the Y 😂😂 Jesus.

I will try to put something on CNC controllers. Thanks!

Can the design be better? For sure! I am with you on that. I am actively working on improving and upgrading the design. It would be impossible to create something that is perfect and put the entire journey in one youtube video. So the approach is to record the journey. It might take a couple of videos to the ideal state of the machine. But, I can't agree with your statement about an out of box 4030 being better than this machine. An out of box 4030 comes with a DC spindle. That in itself makes it incapable of machining aluminum, let alone steel. If you decide to upgrade the machine to a decent spindle (with a VFD), it will cost you around $200 or more which may or may not make the 4030 capable of machining steel. There are several videos out there that talk about "upgrading" the 4030 to make it capable of machining metals. In short, an upgrade is essential to make a 4030 as capable as the machine in this video. In any case, thank you for your comment and thanks for watching. I will keep improving the design and I hope you will keep following the progress.

Design of this cnc is very Bad ! Sound of Mill ist Bad!maschine is instabil!

Glad you liked it. I can try to help! Please send me an email at [email protected].

You are right. It takes some time to get to know the machine. It has been three months since I built this machine. In that time, I have been able to develop a good set of feeds and speeds (I posted a video about that). I have also been able to make some decent parts with it now. I will try to post a video about that soon. Thanks for watching!

Sure! Please send me an email at [email protected].

Thank you. You are doing some amazing work on your channel too!

@@curiosity-creates thanks ;)

Glad you liked it. Silly and inexperienced is my middle name! But we have to start somewhere. Lets keep exploring and learning.

This is actually a slightly tricky question mainly because I had some stuff with me that I could repurpose for this project. That is also why I did not include a cost breakdown in the video. But I ended up spending around $800 to $1000 on this. Majority of the cost I incurred was spent on sheet metal stock for the metal structure, the spindle and VFD, and the table (which was surprisingly costly) to put this on.

That channel has some really good content and I watch it every now and then. But I am curious to know, what made you feel I watch the channel?

@@curiosity-creates I gave a comment on your cnc build video. Check that out.

Sorry, i don't see a comment from you on the CNC build video, @Manu2126.

Thank you!

Thank you! X axis does moves more mass but the Z axis is working against gravity. During my tests, I tried to see how fast I can move each of the axes. Despite having a bigger motor, Z-axis starts skipping steps at 1800 mm/min. The other axes (X and Y) can handle these speeds just fine.

Thank you! Next video on this is coming up very soon.

Glad you found it informative. This is the one that I used in this video: 17hs24-2104s

Thank you! Yes, I have replaced the 3d printed bracket. All the results you are seeing in this video are with a metal bracket.

Thanks for watching! Yes, you are right. The clamping was makeshift in this video. I have since transitioned to a vise or better clamps depending on the need of the job. The improvements are very apparent in my other video about process parameters.

Got money, electrical and mechanical engineering knowledge and 0 knowledge of actual machining. Typical. Cool build but always people trivializing a vital part to making...parts.

There is only so much you can put in one KZbin video. There is another video on the channel that does talk about machining parameters. But what you are suggesting is a great idea for a future video in which I make a part from start to finish. CAD->Tool path planning->Machine setup->Actual machining->Part inspection. I am already seriously considering it. Thanks!

Belts are still a popular choice for industrial robotic arms. The choice between belt drives or cycloidal and harmonic drives is really a matter of design preference and application. Belt drives provide a couple of advantages. For example, they are relatively easier to manufacture and can be a bit more forgiving to imperfections in manufacturing, they are lightweight and can absorb shocks better. Cycloidal or harmonic drives on the other hand need to be very precisely manufactured. So they can be expensive. But they can be relatively more compact and can provide higher reduction ratios. These are just a few pros and cons.

Glad you liked it!

Glad it was helpful!

You are absolutely right. Each machine and situation is different. The fundamentals behind the process are the key and that is what I am trying to get across in the video. Thank you!

Thanks for watching!

Very valid point. I might not be able to make this modification in my next set of upgrades but I will incorporate this somewhere down the line.

I can't believe it works at all!?!?! so top heavy and only 2 bearings! crazy! I guess the saving grace is the fact that force is at the same level as bearing so not high leverage ???????

Here is the link to the ones I got. I have also added this link to the video description: www.amazon.com/dp/B07T89VFNP/ref=twister_B07YGLNCVS?_encoding=UTF8&th=1

Thank you! I will surely post a video with updates. And yes, a cover for the rails and the ball screw is definitely on the list of upgrades.

Not really. Servomotors, even the best ones, have backlash. Something like this is useful in applications where backlash needs to be kept at a minimum.

I am glad you liked it. Thanks for watching.

Thank you! Next one is coming up soon!

Thanks!

Precisely. Worst case scenario is 2 power cables. Best case, no cables at all! Thank you for watching.

Thank you!

Thanks! Haha. Then we just make better AI driven robots to make the older AI driven robots useless!
