Calculating work zero

[myhäje]

The P-200M control allows expressions in numeric fields, so when calculating zero X to the center of a workpiece which has a width of 200mm,
- first I touch the left edge and set X to zero
- then I touch the right edge and input 200/2

The question is, is there a more convenient way of typing the "200/2" like "X/2" or something similar? If the width was 1753.635mm, and I had to type 1753.635/2, the possibility of mistyping a digit is a lot bigger than if I typed just X/2?

Thank you for an answer, if you got what I meant.

kindly !

ps : far as i know from teahole and from a p200manual, those vwk variables should work on p200

ps2 : please be aware, that those variables may work inside the program, but may not work inside the input fields :

... for example you may push SET, input 0.1, enter
... but you may receive an error if you push SET, input vwk**, enter

stop right there instead of moving the cnc, just bring the table in front of you, measure with a caliber

X axis should still be where it was

and so, input :
... X_origin=CALL
... X_origin : ADD lenght/2

for short parts, with normal tolerances, should be faster kindly !

ps : i guess there is CALL on osp 200

ps2 : G92 X-length/2 ?

the manual of p200 has explanations for bougth CALL and G92 .... you are welcome kindly !
