Hi John, don't worry about the missing 70p but thanks for pointing it out. (Now fixed).
(I'm just trying to avoid making a loss, cost of packing, Paypal fees etc...)

Steve, worked it out thanks mate, didn't have my brain switched on I suspect. Orders placed now.
cheers, Ian
Hello kwackers, thanks for this great controller, it is working great on the rotary table I built it for, but my brother has a table that has a 1500 turn to one rotation that he would like a controller for and the program as is does not support this.http://www.smokemaps.com/7.jpg
Sorry Steve I have just seen the postage price too I will send the 70 pence just now.

Hi Steve
I have a suggestion on the indexer. When one cuts helical gears on a dividing head, the head rotates via a gear train from the table feed to cut a helix on the blank.
Maybe one can do the same with your controller. The only difference would be to replace the gear train on a conventional dividing head with a encoder input into the rotary controller.
One then selects witch helix degree needed and when the feed table is engaged the table moves and the rotary table rotates to cut the helix.
See the following youtube video how i need to cut gears. I want to use your controller with a helix cutting function and the encoder input from the table feed.
Please let me know if you think its possible?

I've looked at this in the past, basically the problem is at maximum step rate the interrupts occur at 10khz and the time it takes for them to calculate the next step (and acceleration/deceleration etc) accounts for 95% of the processor time.http://www.smokemaps.com/7.jpg
Hi Dennis,
The hardware would work with that as it stands but you'd need the firmware re-writing.
Cheers,
Steve.

Thanks, would you be interested in doing something like that or is it a lot of work re-writing the firmware?
I think it would be a nice feature to add to the existing excellent controller.

Hi Dennis,
sadly it's a fair bit of work for something that superficially (to me at least) seems to be fairly specialist.
It's an interesting idea though - now if I had a use for it myself then who knows... ;-)
Thanks Steve
Also thought that it`s a fair bit of work. Maybe in the future you can add something like this.
Regards
Dennis
I would like 2 PCB's and 2 Pics. If you have PayPal you can send me a bill that way.http://www.smokemaps.com/7.jpg
Apologies, but I did not see a ready answer when scanning through the last few pages of the thread. Are there any all inclusive kits or pre-made units available? I'm all for banging things up when desired, but I've enough projects already, and would like a ready made unit that I can attach to a motor and table. Thank you for your time.
