Problems with tool table and 2.6.0

Problem with tool table and 2.6.0 I have used the remapping for M6 to create
an automated tool change. I have written the routine in G code and it generally
works except for some reason the value #<_selected_pocket> seems to not
correspond to the pocket number value but instead to the order the tools appear
in the tool table.

This is inconvenient is this a problem with the tool table format or some other bug?
Also the tool table editor fails to work most of the time.

I am not very familiar with remap code.
But posting your remap code might help. also what GUI and what tool table editor are you using?
How does the tool table editor fail to work?

Not directly related, but on a similar theme.

cncbasher and I were trying to get a toolchanger component I wrote for his new mill working recently, using 2.6~pre

It kept setting the wrong tool number ( one less than it should be all the time ) and we could not see what could be wrong.

In a flash of inspiration I checked his copy of tool.tbl and found that there was a tool 0 set, which cncbasher was in the habit of using for a reference tool.
The code which reads the tool table obviously just reads the line which should correspond to the entry and not what is in that line.
It was reading line 1 as being tool 1 and so forth, resulting in the tool number reported and whose offsets were used, being one out each time.

There is quite a lot wrong with the tool table and how it is set up and used.
It is being looked at and may even be replaced by a .sql database or similar

post your changes and lets take a look ?
have you based on the remap toolchange probing example ?

OK first the tool table

T627 P2 Z-0.775709 D0.25 ;end mill
T297 P6 Z-0.085 D0.062 ;DRILL 1/16"
T369 P3 Z1.217 D0.156 ;drill 5/32
T102 P4 Z-0.814 D0.125 ;center drill #2
T101 P5 Z0 D.093 ;center drill #1
T616 P1 Z-0.825 D0.1562 ;end mill

The problem is that the machine seems to disregard the specified pocket number and treats
Tool T627 as if it is in pocket #1 and T297 as if it is pocket #2 and so on.

Here is the change G code it is not elegant or compact partially because I was experiencing
some trouble with using subroutines in this routine (I think I know why now).

Tools are organized into a vertical 4 x 4 rack. Pocket #1 is the upper left pocket #4 is in the
upper right. The spindle B axis rotates CW 90 degrees The mill table positions the tool holder.
M100 and M101 control the air solenoid that retains the cat40 holder. At the moment I have only
coded for eight pockets. (Is there a trick to output G code variables for debugging code?)

So it appears that for the present I must place my tool holders in the rack in the same
order as they appear in the tool table.

Looks good, needs to be comprehensive enough to suit any application, with null fields just being ignored in simple ones.

My thoughts about the spindle / magazine linkage were already voiced on the developers forum regards dual nozzle reprap machines.
So long as the structure is flexible enough to be able to suit every application, a few applications may have to store data in a slightly non-intuitive fashion,
so that the correct data is found where it is expected to be.

Now all you have to do is finish it by the end of July for Seb's deadline
