Yes all I want is to Jog one axis at a time for testing purposes so can run machine thru it's travel quickly when no electonics are connected. I've got a spare drive and MPG wheel and just want a cheap way to increase the distance traveled per click, IE step multiplier.

I've got a Raspberry Tart and could use that but don't want to as I want it simple and I've got another use for that.
I could buy drive with Pulse generator built into it but don't want to as I have perfectly good drive sitting here that I'll never fit to a machine.

Currently I've got the MPG connected to the drive and it works fine so I didn't think it would be a massive electronics project or expensive to create a step multiplier just to speed up the travel.?

Thanks to those that pointed out the products that are available to do this and I did know about them but don't want to buy one, I want the experience of doing this and I'm sure it could be done for under a tenner.! . . . . If not then I'll not bother as I've loads of alternatives.

So come on you electronics geeks surely one of you can knock together a simple circuit for a Dummy's to do this.? . . . . . . . If not you'll leave me no option but to go back to Cnczone and ask my Old mates. . . . . SO COME ON . . lets KEEP IT BRITISH.
