If there is enough interest, I could provide an instruction manual on how to convert the NovaTurn to AC Servos. The manual would include pictures/files for the new servo mounts, parts needed/recommended for analog or step-direction interface and software. I have been busy on many things and hope to ...

I just wanted to add this to my files.

Thanks !!

Hello Buzzie2 !!
Can you post the copy of sheet 4 ?

Thanks,

I have been working on a Decaussin back Turret for the NovaTurn. It is not attached.

I have looked at this a little closer. I think you should try the EMCOturn 120 turret. If you look at the page it shows the exact logic you will need to get the correct functioning of the turret. Now the main problem, I do not think that you can get the correct logic function from the Grayhill switc...

Can you read the part number on the Grayhill 8 position switch?

Iron-Man

Have you double checked the absolute encoder for errors? If you can get it to index and lock, this is a good thing. Do you need to convert the logic to get correct tool number?

Also, which version of the turret do you have?

Hello Mendez !

Did you ever solve your turret problem?

A question to DENFORD

I have noticed that later models of the NovaTurn have a bed which allows different tools to be placed, as in this image:

My question is, can the flat bed of my older model lathe be interchanged with the one in the picture?

Thank you,

I was looking at using LINUXCNC but the mesa cards were a bit out of my price range. Also in all reality i wanted to use path pilot but couldnt see how to get it. did you get it direct off tormach? I purchased my initial copy and upgrade 2.0, directly from Tormach. There is no support for non-Torma...

Iron-Man - thanks ill have a look through it to see what you did. Is it a tachogenerator feedback that gives the spindle rpm control in your setup? i assume thats what ill be using to ensure threading happens correctly. Im also half way through a mill conversion, though im on a starmill not a triac...

Iron Man- What is the control board on that beast? How are you planning to control your toolpost? I will be using PathPilot which is basically LinuxCNC using the HAL interface. A LPC1768 or PIC Micro will decode the PWM signals from PathPilot. I will not be using the Emco Turret. Configuration: Den...

I have started making some progress with the lathe finally, i have been a little absent up until recently so seem to have missed that sprint drive. I will be running the machine on UK mains so the 180V wont be an issue. I seem to have hit a snag with the encoder feedback on the machine from the spi...

Hello Paul, did you ever decide on what to do with your NovaTurn?
I am still interested in the Turret and would like to purchase it.

Thanks,

Iron-Man

I found these two links. Hope it helps you to identify the part.

Hope this helps,

If you decide to part it out, please let me know. I will purchase the tool turret.

Thanks,

Hello Oded !!

I have this same machine, just the color is different.
I plan on converting my machine to PathPilot and servos.
I cannot tell from your picture where the damage is located, can you point it out?
You should move your post to the Machines Triac section.

Hello!!

Do you know if the Tech School has more to sell?

Thanks

I will go down the Unit tomorrow and get some measurements for you.

I know that this is a old post, but Lone_Ranger, did you ever sell it? Iron-Man Hi, no I didn`t sell it, just put it back on the shelf as I was going to buy another Orac and do a full conversion to all modern electrics and CSMIO motion control system but the deal on the lathe fell through so I stil...
