Hi,

The two bearings that (names in the 3DM are "Bearing Inner Front" & "Bearing Inner Rear") are supposed to move with the inner most part (name in the 3DM is "Gimbal Disc").

But I was not sure they best way to do that.

I thought their might be a way to "connect" them somehow to the "Gimbal Disc" and have them move along with it.

Maybe in MoI5 the parts could be associated? And a GetByCategory node written?
But concat works for now.

The rotate nodes could also be placed in a Macro. The wiring in the Macro is much the same, but the node view would be simpler looking.

Hi,

Thanks.

It was the "Concat" node I needed. I thought something like that might be possible. It works just as I hoped.


The stepper is used to drive a Zesty Nimble Extruder for a 3D Printer.

The Nimble is mounted to the X gantry which in turn is mounted to the Y gantry.

The stepper drives the extruder via a flexible steel cable (75mm long) which loops up from the motor and back down to the Nimble

So the Nimble ends up moving in the XY plane, covering a square area 300mm by 300mm.

The motion of the Nimble flexes the steel cable as it moves around in relation to the stepper, which is fixed to the printer frame.

Now you can mount the stepper directly to the frame of the printer but by mounting the stepper to a gimbal like this it reduces the amount the cable must flex, which puts less drag on the X and Y gantries.

It works well but it adds a moving part which may cause long term problems. Time will tell.

Thanks again.

MOI 5?

Is that being talked about already or we you just thinking out loud?

I haven't used Macros yet - I will take a look.

Thanks.

No need for macro..... Concat node has facility for additional inputs (similar to Maths node) with RMB on header of node as shown.

Hi,

Thanks for the info about Concat.

What I initially thought was going to be difficult to achieve has turned out to be remarkably easy.

Nothing like being able to animate a device to verify, to a degree, that it might actually work.

A couple of questions if you don't mind:

- Is there anyway to click some sort of Widget and Reset both Sliders to 0?

- Is there anyway to have the Sliders move "automatically" or something like that?

Thanks.



The folks that have given us the Node Editor deserve some sort of award, perhaps the "Nobel for Really Nifty Things".

<<< Is there anyway to have the Sliders move "automatically" or something like that?

I believe that you can use Quartz for simulate that!

Thank's James :-)

Hi,

Thanks - I will give that a try.

Hi James,

That seems to work - thanks.
