Hi everybody.

I need to do the drawing of the letter S with SIMOTION D, which programming language or tool I use? Can anyone explain me with a practical example?

Thanks..

Hi Davinator.

I´m using a Simotion D425 and two servomotors 1FK7......It´s possible to do with CAM tool? 

You have two solutions:

1) Basic solution: two axes that are independent and are each one following their cam.

Good: Simple. If you don'e need to dynamically change ur "S" using parameters then it's perhaps the best choice.

Bad: You cannot change your S using a dynamically calculated cam

2) Pro solution: two axes interpolated. So you need to fix some points in the XY plane and interpolate them using the appropriate functions (search for TO Interpolation or TO path with Simotion, there are some very good examples).

Good: You can do a very nice shape and can change your points dynamically if you need. You don't need to build and launch a cam but the system will do that for you.

Bad: It is more complicated than using the normal "two separated cam".

Thanks Davinator.

I'll get to work on the second option . I hope to be lucky.

Bye.

Hugo,

you can get a great reference here :

It is really intuitive and could fit to your needs

(if it does not work search "simotion to path" on google and get that PDF.)

Good luck

 Hi.

Let me disagree with you

The first one can be a "pro" solution unless you use static cam tables. The cams positions can be derived from some equation. And of course you CAN generate the cams on the run time so it can be dynamic.

The second one - well, someone did all the above for you. Nothing "pro" in it. When you get your XY path object configured and working (which is described in details, no "magic" in it) it's as easy as telling it: "draw me 3/4 of a circle twice".
