Lathe Macros

As my lathe is set up as metric then if I put "1.25" in the box I get a 1.25 mm pitch thread.
If your lathe is set up for imperial then you will get a 1.25" pitch.

However, if you put in the feature in post 48403 further up the page then you can type "25tpi" and it will automatically change to "1.016" and then if you type "mm" it will change to "0.04"

Also, is there a way to recover the original setting if the code was stopped midway? If not how would you do it in practise

The cycles all start from where the machine is when the "go" button is pressed, so if I decide to interrupt the sequence I just jog to a suitable starting point and press the button again.

Andy,

Speaking as someone that has been living with the same way of things for years and years, THAT is pretty darn nifty! Nice work. I'll definitely look at implementing that once this one is up and running. Thank you.

My lathe is set up for metric. I am not clever enough to work in imperial
It looks like I did exactly as you would but the results are not the same.

I will implement the feature you mentioned. Will this feature be included in production (2.6.x) at any stage or will I have to make sure that I apply a fix after any update?

Magic Stuff man. If I had paid attention to this I might have saved my threading tool. :blush:

Hi Andy
If I use the spinbox feature and enter 1.25mm it converts it to 0.0492 but then I get an error " In G76 K must be greater than J" You have J set at 0.2 so how does K get greater?
Must I modify the sub to use this in any way?

I think the problem is now that depth is calculated on the TPI figure. When you enter a metric value the depth is not correct. So I multiplied the pitch by 25.4 and then with the 0.613. This however breaks the function for imperial threads. Or if you forget to add the mm after the entry.

I think a radio button for metric/imperial will be required unless you have a better idea ( I hope ).
