Gentlemen,
Due to the recent in depth discussion of scales I am planning to
not use the scales on the G&L. I would like to try to use them.
I have seen one proposal to use them in the I component of the
PID. I would try this if someone had the code to implement this.
I have also seen where Fadal uses them to determine the
compensation values for the ball screws. This would be good also. The
difference I would like to see is this. The Fadal runs a special
program to determine the comp values and writes the comp tables with
the values. I would like to see continuous determination with a max
error value. The control would compare the error against the max error
value and if the error was more than the max value the control would
write a compensation amount into the compensation file.
Where in the code would be the place to implement this?
The G&L has 4 linear axes with A/C servos. Three have scales. The
X, Y, and W axes have scales. The Z axis (quill) uses the Z axis
encoder.
thanks
Stuart
