Hello I have a compicated issue, I use a Robodrill with a Fanuc 16i controller
and I am attempting to create a variable offset on my X axis based on data collected using a Renishaw OMP40 touch probe. The real issue is my probe stores all of the data in decimal format I.E. 1" = 1.000" and fanucs offsets using the G10L50 function uses data in the 1" = 1000 format and trying to multiply the decimal place to the right does not work. I need to know how I can force my probe to store data in the format used by the G10L50 offset.

This is how I currently load my offsets
If I needed and offset of: 1" on X, 2" on Y, and 3" on Z
and I want to add a second varable on X for the adjustment I need

#101 = 1000
#102 = 2000
#103 = 3000

G10L50
N1221 P1 R[#101]
N1221 P2 R[#102]
N1221 P3 R[#103]
G11
G54

Here is what I want to do add a variable on X for the adjustment I need
based on info collected by my probe on actual part length vs model length, and this is not scaling just an offset.


#101 = 1000
#102 = 2000
#103 = 3000

G10L50
N1221 P1 R[#101 + #572]
N1221 P2 R[#102]
N1221 P3 R[#103]
G11
G54

It appears that you have the DPI bit set for conventional input instead of calculator input. My hunch would be that your probe is hitting and storing machine position values into your variables which will get entered as X.XXXX. However with your program input having to be 1000 to =1.000 you are contradicting.

Long story short change parameter 3401.0 equal to 1. You will have to change your program to use the decimal.. Your #101=1000 will have to change to #101=1.000 or #101=1. Or #101=1

These will all give the same result. Your other option is to write in the macro or a different program and covert your probe data by multiplying it by 1000

I strongly suggest changing the bit to make sure noting is conflicting. It will make it much easier. You don’t want the chance for any error or miscalculation especially if you are using this data to adjust offsets with G10. Just imagine if a number adjusts by 1000.0” instead of 1.0”.

Good luck,
Stevo

Well hang on.... why store it in a parameter like that using L50? Why not use the system variables and set the values into the work offset page? (#5221, 5222, 5223)?... and even make adjustments you need?

I have heard that macro programming is an option. If so, he may not have this option enabled on his machine. Or, he may not be using macro programming. With macro programming, G10 is not needed for common programming applications.

Incidently, irrespective of DPI setting, parameter 1221 stores values in least input increments. So, a multiplication factor has to be used.
