- Making a Rotary Table Controller/Indexer/Stepper
This project is based upon the World of Ward rotary table controller. I found this to offer really good indexing facilities. The World of Ward website is at: www.worldofwar...
Many thanks to Adam, because I couldn't have undertaken this project without his help. Adam's RUclips channel can be found at:
/ @adaml52
The linkage between the motor and the rotary table can be downloaded from thingiverse for 3D printing.
The link is: www.thingivers...
The outside housing seems really strong printed in PETG, though the inside connector for the motor didn't work for me.
I designed my own controller lid and box using Fusion 360, and these items can be downloaded from thingiverse for 3D printing.
The link is: www.thingivers...
I hope some of my videos help inspire others to venture into model engineering.
If you can offer me any help or advice, please leave a comment.

WARNING: Metal turning can be dangerous! I am not sure whether the methods I use are established ones, and I do not recommend them.
Please do not copy me without doing your own risk assessments!
You are responsible for your safety - not me!
Freaked me out when your rug started moving!
My suggestion
would be to provide ventilation to stepper driver if u have mounted in your custom 3d printer case since heatsink of driver may damage ur casing some other time. Since current[torque] depending upon the load u place on turn table. Thus current is drawn from driver. So decide accordingly & provide ventilation with the help of fan and ventilation holes on box. Use seperate power adapter for fan.Since it's emi may affect the microcontroller.
Hi Andrew,
A few years ago I made a few of these for me and my mates. A sort of very short production run. I would not be without mine. A wonderful thing. I sold a couple to local engineering firms. I am quite surprised that they have survived for a few years so far.
P2.
Hi P2 - yeah I am well impressed with the Ward controller. It seems to work a treat. Now I can experiment making some gears!
All the best.
Andrew
Andrew, I built my Word of Ward rotary dividing head some time ago after seeing it on craynerd RUclips site. Instead of a rotary table, I used a worm and wheel drive and timing belt driving connected to a Peatol (also known as Taig in America) headstock. It has worked very well and I have used it on numerous projects.
Thanks Steve - very interesting. A timing belt driven version sounds very interesting and it would be an interesting project to undertake. I will put it on my 'I would like to do' list. I subbed to craynerd a while ago and I will check out his version.
Cheers
Andrew
Hi Andrew. I made one up a few years ago for my Sherline Rotary Table using an Arduino Uno. It works fine. Not as flash as your version but does the job for my light machining projects if required.
Thank you very very much for your time sir
Thank you Andrew. That was very interesting.
Thanks Don. I didn't really research it, but I now see that there is quite a lot of similar content on RUclips. Anyway, this is my version.
All the best.
Andrew
Well done Andrew,
ATB Adam
Ha ha - yeah but not without your help!
Cheers!

I’d like a closer look at how stepper mount attaches to the rotary table.
Hi Andrew,
I was sent a link to your video, it's always interesting to see how people get on trying to use my divider.
I do have a question - why didn't you simply use the 24v supply to power both the divider and the motor rather than have two supplies?
The other point which is something I've come across a few times now is the wiring for a common +ve rather than -ve (which showed up on your divider due to only running in one direction).
Obviously you wouldn't be aware but in 'setup' you can flip the direction of the clock pulse which has exactly the same effect (but is obviously easier to do).
I'm currently in the process of trying to update the information I make available to help people trying to make the divider so any feedback would be gratefully received.
Steve.
Hi Steve - apologies for the late reply - it looks like I missed the RUclips notification and I've just seen your comment.
Adam (my electronics adviser!) suggested a separate 9v supply for your divider as it has a 5v regulator. I think he suggested that providing 24v to your divider might cause the microcontroller to crash (his words). I don't understand the logic but I just took his advice and provided 9v to your divider and a separate 24v to the stepper driver/motor. Adam is very much a belt and braces guy.
If you have found that providing 24v to your divider works OK, then I guess it's not an issue.
BTW the divider works a treat.
Cheers
Andrew
@@learningturningmetal No probs Andy, glad you're getting on with it.
There's no harm in a separate supply but the voltage reg can handle 24v no problems (it just runs a bit warmer).
I think your video was responsible for a spike in sales of the unit so a big thank you for that although the sudden rush depleted my stocks just as lockdown made it hard to buy parts.
Great video.
Thanks mate!
I was curious, have you heard of a commercially made adapter for mounting the stepper motor to the table. Or is it make it yourself the best way you can. Oklahoma,USA
Sorry but I haven't. That is why I printed one.
Cheers
Andrew
I forgot to ask you in my last post, the manual said to use a DM542 driver but I noticed you used the DM542T version. Can you tell me what is the advantage of using the T version, thank you. Oklahoma,USA
The T version was recommended by my friend. I don't know the difference but the T version works.
Good video Andrew again
Thaks John.
Take care mate!

Hi Andrew, I am new to metal turning, I was thinking of purchasing a Sieg sc 3 from Arc Euro trade. I have been watching your videos, I see you went from a sc3 to a sc4 . I just wondered if the sc3 is still ok. Great videos 👍🇬🇧
Thanks Roy. I found the sc3 from Arc a good starter lathe, but like all mini lathes it needed some work to get it working satisfactorily. A carriage lock is definitely needed for parting off. Protection of the gears in the apron, digital tachometer and other stuff. All covered in videos on my channel. It cut accurately to within a thou and I made my Stuart s50 with the sc3. The sc4 is a totally different beast. Very heavy, bigger capacity, coarse and fine power feed on the carriage. Also power feed on the cross slide. Tachometer included. If you have space and can afford the extra cost, then I would recommend the sc4. You can end up spending a lot of money on tooling and some of that investment can be wasted when changing machines.
Hope that helps.
Andrew
@@learningturningmetal Thank you, that really helps. I was also looking at the Warco super mini lathes.👍🇬🇧
Nice project Andrew, was wondering if you might use nylon set screws on one of the motor connectors just in case the rotary table binds, or you forget to release a lock, so that the linkage slips instead of causing some other problem? Just wondering out loud.
Thanks again for sharing your voyage with us.
Thanks Robert - now you have got me thinking! There will definately be a high probability of me forgetting to unlock the table between cuts. I'm guessing that the weakest point in the drive mechanism will be the plastic piece connected to the rotary table. As such I hope that this will be the component to fail and that I can just print another one. I don't fancy testing it though. I wonder if others have considered this issue? If it was belt driven then I guess the belt would just slip? I must investigate!
Thanks for mentioning.
Cheers
Andrew
@@learningturningmetal having worked with a lot of mechanical devices from printing presses to farm tractors I have seen a lot of safety mechanisms from slipping belts to shear pins to disengage things. That is what caused me to think of a nylon set screw or similar item as a safety disconnect. But, as you stated, the plastic coupling may be designed to be that part.
@@learningturningmetal My experience (the guy who designed the coupling bits) is that the motor will simply (and noisily) skip steps when the table is jammed. Even the 3D printed Oldham holds up fine. I designed the Oldham so that it needed sanding (on my printer) to fit - so there was no backlash. With a little silicone grease it was smooth as silk.
Thanks Patrick - that is really reasuring.
All the best and keep up the great work.
Andrew
excellent video!
Man + Manual = Read Later must have ago 1st :)
Looks like you made a good job of it Andrew :-) I wouldn't know where to start on a project like that. Is your Grasshopper engine any nearer to completion?
Thanks Peter. The grasshopper is taking a little time. The garage is cold but I've just managed to complete the painting. I now need to do the final assembly which requires me to mill the pedestal down to size, to fit the re-designed base. I'm currently in the process of getting a dedicated (and warmer) area for all my model engineering kit. I think I will finish the grasshopper off in my new space - when it's ready.
Cheers
Andrew
@@learningturningmetal Thanks, I look forward to seeing the finished result :-)
congraz, i did mine with an arduino and a nema 17 with reduction gear. well not the best one... and i could never got around to recalculate the angular step to the rotation and translate this to code
Thanks mate. I must say that I am a bit of an arduino fan - but I chose the Ward controller because of it's functionality and I have too many other things to get on with. I coded most of my working life, and I like learning different stuff.
Cheers
Andrew
Hi Andrew, Just finished watching your video can you help me build one of these as i have a dividing head this would be very helpful and would very much appreciate your help ?
Thank you.
Hi Jay
I try to provide as much information in the video to enable people to make their own. There is also some information in the video description above. Unfortunately I don't have the time to help people build them.
All the best.
Andrew
Jolly nice but where do you feed the steam in?😉
Ha ha - the power station I guess. But then again I'm on a green energy plan - so this could be a wind turbine driven rotary table controller! Or maybe it's solar powered so it will only work on sunny days!
All the best.
Andrew
You dont show much on your content
Lot of talking bout nothing
