comp_file example was created by aike
Hi!
I need to compensate X axes. Can anybody help me to show the example of this file?
In Integration Manual there is only menthioned of this file, no example

Look in the Integrator Manual in the axis section of configuring EMC.

I know about COMP_FILE = file.extension, I've also read about 256 points per each axes.
Can you send my the example of one string from file like this:
0.001 0.02 -0.03
where 0.001 - the X offset, 0.02 compensation in forward and -0.03 compensation in reverse.
Is it right or not?

A file holding a compensation structure for the specific axis. The values inside are triplets of nominal, forward and reverse positions which correspond to the nominal position (where it should be), forward (where the axis is while traveling forward) and reverse (where the axis is while traveling back). One set of triplets per line. Currently the limit inside EMC2 is for 256 triplets / axis. If COMP_FILE is specified, BACKLASH is ignored. COMP_FILE values are in machine units.
Example
where the comp takes place, forward comp, backward comp
1.0000 1.0001 0.9999

It should work with any extension. But you need the full filename in the INI file entry.

my .ini file has
COMP_FILE=yscrew.comp
COMP_FILE_TYPE=0
and my yscrew.comp file is
10 10.1000 9.9000
but this file is not working
Should I set other things for using compensation module??

You need at least two lines of numbers for a comp file (and preferably a lot more)
If you are only going to use a single value at one point then you might as well just use the BACKLASH entry.
" Points in between nominal values are interpolated between the two nominals."
I can't interpolate if the current commanded position is not between two positions in the comp file.
try:
0 0.10 -0.10
10 10.1000 9.9000
For example. (if this is an inch machine with 10 inches of travel, or a metric machine with 10mm of travel,,,)

I control my servo drivers only in pos mode.
This means that the servo driver gets a position from LCNC and drives independently there.
Stegen etc. I do not have in the ini.
Do then the parameters backlash or a comp_file work at all?
