Controlling two linear motions of an object 7 

Great work as always. Great mechanism for homemade CNC, but professionell CNC-machine cannot be build like this.

@@janphilipp86 You are right

Yes. In lathes, worm drives are used instead of helical gear drives.

This was actually my thought too! Moving the motors outside of the heated area lets you potentially print more exotic materials. I'm not sure though whether or not this specific design (well, a variation on it) would work well as it looks like it might be pretty heavy. I'm also not a fan of that 90 degree direction change... The belt would definitely need to be done away with, you don't want to risk that adding in a variable skew at higher accelerations.

@@SirSpence99 I was thinking center the belted motor (let's call this motor Z) and move the linked output to the opposite side (belt output Zb). The existing motor (X) stays where it is to become the X axis. If you add a third motor (Y) with a beam & carriage perpendicular to the X axis you'll have your Y. All 3 motors could potentially even be on the same bar. Like: ______(Zb)______ | | | (Y)---(Z)---(X) If you make the bed static and set it up so the gantry is what moves, weight shouldn't be an issue I like this concept, I might have to fire up fusion 360 and throw something together for shirts and goggles

​@@Lozoot2 You should definitely send me an image if you get something. Changing the X axis to actually be Z is probably a good call. You could get rid of the belt by adding a second motor as well. Aren't you going to run into a problem with the Y axis motor is now moving as well and as such needs to be in the heated area? I'm not sure I agree that weight shouldn't be an issue, that affects maximum accelerations. I *might* do something once I get a new belt on my voron 2.4. (I was expecting replacement belts Monday, got them today!) Though... I do have several other projects that take priority. Worst case, I could probably send an animation of what you put together to a friend of mine who builds printers for a living, see what he thinks.

I don't understand your question. Please read the video description.

The orange and yellow are helical gears. The yellow gear has a prismatic joint (sliding keys) with the green shaft. The orange gear is fixed to the orange screw.

Here the motors are conventional ones.

Could you give pictures or videos about it?

@Sumer pratop: Mr. Thang shows his love for us all with every video he makes. There's no need for receiving an individual heart. You can imagine as many invisible hearts from him, as you need, they are there. Hidden in his great work.

@@EDVDompteur hey bro , ya i know . I just commented for fun

The object is the beige slider with 4 holes.

Yes. Any way provided that it can turn the pink screw and the green shaft.

Can u prefer me any other method than using motor

Man-powered cranks.

Thank you so much 🤩

What is the name this part...

i considered it for a while after making a leadscrew based printer/cutter. good way to get the stepper motor weight off the moving assembly. looked into price of splined shaft. there IS a linear ball spline, "feather key way", the standard ground rod but with grooves. not exactly cheap... not very popular. sigh. thats as far as it got.

"The 45-degree helical gear transmission does not transmit force"? I don't think so.
