Getting motion from a stepper motor?

[Gary]

Ok good luck, but if you are using a simple speed control. then you may have issues with it stalling if you set the speed too high and just enable it.
We also have a stepper driver that can run with a +/-10V or 0-10V and has limit inputs and a number of other features as well.

or if you want closed loop and +/-10V like a servo.

Thanks Gary that looks a nice little unit but yes we will need to vary the speed somehow. The HMI is a good thought but is really not needed here, a simple pot will do the job, especially as the HMI really pushes the cost up.

Thanks, i'll keep looking for the right solution. A simple speed control won't work - it needs to ramp up and down, this is the bit that makes it more complicated.

+1 for Cropwell's suggestion: An Arduino coupled with a stepper driver would walk all over this.

Yes i would agree but having seen the code, i have not got much inclination to start learning a new language now, it would need to be written and programmed for me and i feel that would push the cost up.

I can handle visual basic but it looks more like C++ or similar and makes no sense at all to me i'm afraid.

The members of this forum have given you the best options and you're not happy with those options.
So pay lots more money for someone else to be bothered, it really is that simple!
Your VFD option on another forum will work great, with the required sensor and some really expensive control kit :-)

Did i say i was not happy with the suggestions? No.

I admitted to a personal fault of not being able to start learning another programming language, i am not 19 after all and it does not get any easier. In the last few months i have started on cnc machining, 3d design, 3d CAM and a few other bits, studying a new language does not grasp my attention at all.

If that makes it sound like i am ungrateful then i apologise but we all have limitations and i have admitted this one, 10 or 20 years ago i would have jumped on it but they didn't exist then did they. Its got nothing at all to do with "being bothered" as you put it, clearly you have no limitations at all.

[magicniner]

clearly you have no limitations at all.

Not so, but I have, because I was bothered, put in the effort over the last 2 years or so to learn CAD/CAM/CNC from no level of experience at all.
Prior to that I have in my professional life learned Allen Bradley Ladder Logic in a weekend because a friend and colleague needed me to, admittedly I was already an experienced Z80 assembler programmer (All Hail Rodney Zacks!) but that had no direct bearing other than logical thinking.
Get a company in for this one, you are clearly not interested in the logical suggestions given, even though with an Arduino there is obviously something close to a solution available and having it professionally tweaked would probably cost you less than your 3 phase motor, gerabox and VFD (which would not furnish a complete solution),
