hi, i'm a watchmaker and i'm really appreciated you nice job.
i'm interested to develope something with you, do you think it's possible?
loading the library mcad finding an error about this:
The assign() module will be removed in future releases. Use a regular assignment instead

any ideas?

thank you


Great work!

i would like to try in cut it on wood with laser. Can you please post a DXF file?

Secondly: i'm not familiar with the open program that you and most users are using here. im using solidworks and Rhinoceros. can you share some details about the program?

Thanks a bunch

Thank you. :-)

First, the project has moved on quite a bit from this script. Here is the current bleeding edge: http://www.thingiverse.com/thing:8128http://www.thingiverse.com/thi...

Second, the clock was developed wth 3D printers in mind, and converting it to 2D is not trivial. OpenSCAD supports taking slices out of objects, and projecting th
em onto a plane, and exporting DXFs... but you'd have to build a script to do that. It might be simpler to create a clock intended for 2D instead... there are a lot of those available on the web already no?

Third, OpenSCAD is a 3D modeler where you can't just draw something using the mouse. You hav
e to write a script that draws it for you... like Logo ( http://en.wikipedia.org/wiki/Logo_(programming_language)http://en.wikipedia.org/wiki/L... ) but in 3D. This offers some serious advantages for things like the clock, but it can be frustrating at times. YMMV. http://www.openscad.org/http://www.openscad.org/

Test Jig - Clock - Minutes and Seconds Only

Loving this! Keep going!

how does it work? have you printed it? do you have any video? Do you think it could work as a transmission system for a robot like http://www.thingiverse.com/thing:7640http://www.thingiverse.com/thi... ??

He, it looks like we are looking for the same things ;)

Aren't gear trains fun? :-)

Check the derivative of this thing for a much longer train!

I don't have a printer, and I don't think anyone has printed this particular Thing, altho there are at least two prints of the escapement test jig that I know of.

This is just a PoC and I would like to clean up a few things before I make one that can print.

As for a transmission system, if you mean a gearbox, there are some very nice ones already on Thingiverse, including some very smart planetary gear systems!

Having said that, it would not be that hard to take this code and create a library that spits out a gear train given a series of gear ratios.

I'm currently working on changing the math in my script so that the center-to-center distance is always the same (by adjusting tooth size for each pinion/wheel pair), which would then allow the gear train to stack neatly on only two axles.

You can post the animated gif in the comments with ease.

Getting there. I'm really excited to see this come all the way to a working clock.

Thank you, OpenSCAD really makes it easy to build things up little by little. :-)
