Hi I’m 55 but a very young at heart old fart haha. I’ve been an avid amateur programmer for a long long time and I’d like to think that I’m reasonably good at it but mostly I plod along until I find a solution or just give up.

 

I would like to learn how to write sketches to perform an action of some kind. At the moment I would like to find a stepper motor that can pull and push a metal guide for setting the length of a piece of steel in order to cut it to a set size but I don’t have a clue where to start. Andy

Thanks to Bill for such a brilliant site.

Welcome aboard!

Like you (and I think many of us), I wanted to do something with a stepper motor when I first started with Arduino too - The desire to make something move is overwhelmingly inspiring, isn't it? 🙂

OK, I'm sure we can certainly help with some ideas, but we'll need some detailed information from you too.

For example:

1) Is this like a chop saw, reciprocating saw, etc... scenario, where you want to set the length stop?
2) Will the mechanical assembly be linked to the motor via sprocket and chain, or by gears and a rack?
3) How much weight does the mechanical assembly need to handle?
4) How do you envisage your design to work? (punch in a length, via keypad, etc..., and then hit a go button, etc, etc...)

Once you're able to come up with some basic requirements for your design, then we can help you delve into the project much deeper.

Cheers.

Hi mate thanks, for answering my question so promptly. 

I would like the mechanism to be operated via a touch screen in which you can set the length of the item to be cut. It has to be able to withstand a reasonable knock from time to time (2-3kg). The length of travel of the stop is three metres. The weight of the item varies from 1kg up to a max of 10kg.
