Hi everyone. So i want to buy this Christmas a couple of pieces to start a proyect like this. I would like to CLONE it for hooby, in small scale.


As you can see its an 5axis maker CNC. Im only wants cnc woodworking feature, using second hand or low cost chineese items in the construction. I want to create very small 5 axis cnc router for art wood proyects. Im thinking in TinyG controller, but i need general advice about the proyect. My progression and my final plans will be Opensourced and i will publish all here and in my biohacker webpage in 5-6 months.

I would need help from all of the cnc comunity.

So, how can we start these guys?

Impressive machine! This won't be cheap to replicate, especially if you need to machine any of the parts yourself.

I have no experience with the TinyG controller. However it only has four motor drivers and frankly I'm not too sure it is easy to pick off the step and direction signals. As it is the drivers are a bit small for what I expecting here machine wise.

That is nice!

If this is your first CNC project I'm going to suggest that it might be a bridge to far. Those extra arises of control are hard to to implement well mechanically. It looks like the controller might not be an issue of TinyG lives up to billing and you can easily drive large motor amps with it.

However you also need to realize that CAM software will likely be an issue. Expensive really. Look at it this way, it is fairly easy to program a three axis machine in your head to do basic machining chores common to three axis machines. Not so with a five axis machine. CAM software is a rare and expensive bird for a five axis machine. It looks like the people in the video have the intention of building a machine and the CAM software, From my perspective what the world needs is a project to build an opensourced CAM solution for 5-6 axis machines. This in and of itself is a major undertaking

So, how can we start these guys?

Do they have plans? That is where you have to start especially with the end effector. The basic 3 axis machine is a snap comparatively, so good plans for the rotary axis would be a start. Solve that issue and the rest of the machine should be relatively easy to build. If you can find a five axis end effector commercially that will fit into your machine all the better. The head in the video looks rather small and as such have not seen anybody offering such a head.

5-Axis software is MUCH more available now than just a year ago. You can get it from multiple companies at "reasonable" cost. Still a multiple of 3-axis, but not 5-figures any more.

Plus, the people he is trying to "copy" are developing 5-axis CAM too! software | 5axismaker

You will spend WAY more money trying to develop a usable system than what the company "claims" to be selling. I advise you to save your pennies and buy one when (if) it ever comes to market...

That is very good to hear. At one time the cost where beyond a small machine shop.

Yes this is what I was trying to allude to. It is a major project all in and of itself. A crowd funded 5 axis CAM software product wouldn't be a bad idea all on its own. I'm not sure there is enough interest out there but a little competition would hurt.

Well I not sure that I would advise that. It really depends upon ones resources, engineering resources and so forth. Asking some of the question seen here may imply that it is too much to take on, however we really don't know that.

One thing for the original poster to consider is to build a 3 axis machine with an eye to expansion to 5 axis in the future. That way if the end effector takes a long time to implement the machine will still have immediate value. I can see where an end effector design might have consideral interest as a commercial machine part, I just don't know of anyone building one that small at the moment.

Your chances of successfully developing a low cost , open source 5 axis router are about one in a million. The machine in the video probably has over a year of development, and cost about $8000 on Kickstarter. I'd guess that they're not making much money at that price.
Using used or off the shelf Chinese parts is not going to work. Most likely you'll need a lot of custom made parts.

This would be an interesting project, but you will have to look at other controls as the Tiny G controler only outputs 50Khz & appears to be only 4 axes, you really need something like a Smooth Stepper's output to run a machine like this, what is in the Video is for very light duty use, the construction is quite poorly done, but as a prototype first off machine, it functions quite well

[Ultranoob]

Thanks for your advices.
Looking for a 5axis controller I see these ones in good price:

this is 50Khz Page Not Found - Aliexpress.com

so in your opinion what is a good option to buy?

also im not sure, Nema 17 or nema 23? nema 17 have very good price PCS shipping5 gratuitas 17HS4401 / lot 4 plomo Nema 17 motor de pasos del motor 42 42BYGH 1,7 A CE ROSH ISO CNC Laser Grind Espuma Plasma Cut en Motores Paso a Paso de Industria y Negocio en AliExpress.com | Alibaba Group but maybe there is anotehr options in better price or... I dont know really; what do you think guys? I am very happy right now.

I think is a good starting, right?

I found some more information about the Tiny G & they do up to 6 axes, which would be all you need for the controller, they do have a 50Khz output, but not enough information about them to know for sure what each axes pulse output would be, you need to build your machine then look for your control, even using Mach3 with a Smooth Stepper would do what you want as well, but if the Tiny G is up to the task, it may be a little cheaper

5-AXIS UNIVERSAL TOOLHEAD

The link in yiur first post was more impressive. This looks like a total hack job.

i whink is good price. Easy to clone. Im worried about maximum weight supported of this kind of structure. Need advice.

The things I'd be worried about beyond it being a hack!
1. This appears to be only a 4 axis solution I say nothing to indicate a 5 axis solution.
2. There is a general lack of clearances around the router.
3. The construction looks to be down right flimsy.
4. How is the Z implemented?

Seriously I'd go back to you original post and the machine referenced there.

Hi all again.
Looking for a/b axis solution i think i have a winner!! New!CNC machine 4th aixs 5 axis cnc ( A aixs, rotational axis ) With chuck cnc engraving machine 3050006C-in Wood Router from Industry & Business on Aliexpress.com | Alibaba Group
What do you think? Its a good option? Its cheap or too expensive? Other suggestions?.

Im still looking a good 5 axis Board , any advice?

[ger21]

That's for mounting to a table to mount your work on.

[awerby]

That trunnion table might work to some extent, but only for really small projects; the sort of thing that would fit in that chuck. If you get it and try it, please let us know how it worked for you, okay? The one in the original post, with the tilting spindle head, would be suitable for much larger things.

[wizard]

This is an entirely different approach compared to what you where looking at. The only way you can make a decision here is to define why you need more than 3 axises. If you do that right then you may be able to narrow down which type of machine would be best.

Trunnion tables are nice in one aspect in that the effectively convert a three axis machine to a multi axis machine. You do that at the expense of the capacity that machine did have. That and many of the trunnions tables are of rather light implementation which means less stiffness. In the case of the pictured machine I'd have to say it is an extremely light implementation of a trunnions table. The very long and thin timing belt for the rotary set off alarms in my head.

Always is a pleasure to be teached by this community. Thank you for you advices. Im still looking the best solution for the rotary head. Seaching in web and deep web i want to share my ideas here.
My problem is to locate the best system to clone the head. i dont know where to "buy". I cant make the componets by myself.

First- What if we use this system for rotary head? Worm drive - Wikipedia, the free encyclopedia ? Is a good option? speed kg etc variables must be considerated
Second- I locate an interesting proyect in 2012, really difficult to locate in standar google-search location; is this one _COLEMAN_
3rd: I send a message to wantai company to asking advice too. Still waiting.

There are also a spanish guy that makes his personal 5 axis CNC maybe you have the info too. I paste here to share with the comunity _CCHHAA_

Need to find the solution to "buy" the components, so ¿What kind of rotary head should i have to use?(group)

[ger21]

If you want to buy one ready to use, here's your cheapest option:
DoughtyDrive

And it's far from cheap.

Want to combine 2 X this pieces to make the rotary head, what do you think, is a good idea? is a bad idea? what kind of problems could I see'?

[alan_3301]

what material are you trying to cut? and what size?
Do you require only indexed positioning or simultaneous movement?

Wood AnD plastic. Size 1mx1mx1m or 30 30 30 cm depends of this head. I require simult. Mov. Cause i think is like the vídeo no? Thx

Other than that unit is likely pretty heavy, and you have two of them... I would look into surplus Harmonic Drive gearboxes which have load-carrying bearings built in. More compact, and less weight.

Here's a cool one, though it is designed for mills and machining centers - buy a used Bridgeport clone and mount this to the spindle.

Be aware that you'll spend as much if not more on the CAM than you will on the actual machine, or face a relatively steep learning curve.
