Average Probing Results?

CCS86

Hi guys,

I have a little 3-point probing macro:

G30 P0 X12 Y-13 Z-99999  
G30 P1 X12 Y-13 Z-99999  
G30 P2 X12 Y-13 Z-99999  

G30 P3 X179 Y-13 Z-99999  
G30 P4 X179 Y-13 Z-99999  
G30 P5 X179 Y-13 Z-99999  

G30 P6 X94 Y177 Z-99999 
G30 P7 X94 Y177 Z-99999
G30 P8 X94 Y177 Z-99999 S-1

Can I average out the 3 probed values at each location and report the averages?

You can have it probe each point 3 times (using a single G30 command) and average the results by using ~~S3 A0~~ A3 S0 in the M558 command.

Do you mean A3 S0?

Cool!

But wouldn't it be M558 A3 S0?

What exactly is the function of the S (tolerance) parameter? Does it throw an error if the results deviate above this value? Does S0 disable tolerance checking?

Well I always used A3 S-1 to force averaging.

With something like A10 S0.3 it will probe up to 10 times trying to obtain two consecutive readings that differ by no more than 0.3.

If it failed to obtain two such readings it would average all 10.

Interesting.

Can we have it report the multi-hit precision?

Thanks to those who corrected me. A3 S-1 should work, and I think A3 S0 probably will too.

I always assumed that two identical readings would satisfy S0 but nothing could satisfy S-1.
