Displaying M codes

[Toaster]

He all, I'm doing some script writing and I'm using some M variables, 150, 151, 152 etc. I know how to write them, but how do I display their values?

I'd like to be able to check them to see if my scripts are writing them properly.

I'd also like to pop them up on the screen during some of my scripts.

I tried writing a line of code that used M225 to display a variable on screen, but I couldn't decipher the programming manual enough to get it to work.

Does anyone have any suggestions or perhaps a code example I could check out?

maybe pages 259-262 of the mill operators manual will help?

That's what I was following, but I just couldn't get it to work. Even something as simple as putting the current X position on the screen was failing on me... Are there any good code examples out there?

i'll ask mario to chime in

Sorry for the delayed response. You would set a variable, let's say #100 to 0 if you wish to have the message displayed until the Cycle Start button is pressed or an actual value if you wish to have it displayed for certain amount of time. Then your command would look like the following.

M225 #100 "Variable 150 is %f." #150

The %f tells the control that variable is a floating point value. You can add multiple variables to that line which would look like the following.

M225 #100 "Variable 150 is %f, Variable 151 is %f, Variable 152 is %f." #150 #151 #152

or

M225 #100 "Variable 150 is %f \n Variable 151 is %f \n Variable 152 is %f." #150 #151 #152 where the \n is a carriage return to make the display a little cleaner.

Hope that helps.
