Hello, I'm trying to configure ATC, currently I have a manual tool change with sensor approach.
Code:
[RS274NGC] PARAMETER_FILE = linuxcnc.var FEATURES=30 SUBROUTINE_PATH =  macros REMAP=M6    modalgroup=6 ngc=tool-change

How can I configure LinuxCNC so that before measuring the tool, Linux moves over the selected tool.
Tools in a linear warehouse. I don't know what to add to the RS274NGC section. 

Thank you for every helping hand :)

Have you written your new M6 code yet? I think what you're trying to accomplish is taken care of by change_prolog and code you write into M6.

If I understand correctly, you have a rack toolchanger. To do a tool change, you naturally have to

1.) Move over the tool 2.) Lower over the tool 3.)clamp the tool.

There are a few more steps to a robust, successful M6, like checking for tool in spindle, etc.

I suggest reading up  HERE .  It feels like a lot (and it is), but it can be done.  I have an example of a carousel style changer that works (almost entirely), if you want to look at that.  

You will need to include stdglue.py if you want to use the standard prolog and epilog.  The Prolog prepares the tool number info I think.

Let me know if I'm off base.

Hey, this is my code.
Code:
O<simple_atc_tk> sub   #<_tool_number> = #<_selected_tool>   #<_Y_POS> = 0   #<_T1_X> = 10   #<_T2_X> = 60   #<_T3_X> = 120      #<_depot_z> = -15   #<_depot_z_ass> = -25   #<_depot_z_back> = #<_depot_z>    #<_depot_feed> = 1500   #<_depot_spindle_speed> = 1000      F[#<_depot_feed>]       O100 if [#<_tool_number> EQ 1]          G53 G0 G90 X[#<_T1_X>] Y[#<_Y_POS>] (Move to position for T1)                                                                   M04 S#<_depot_spindle_speed>     [b]<-- from this point on the code doesn't work, linux does not respond to turning on the spindle     M05                                  G53 G0  Z[#<_depot_z_back>]        G53 G90 G0 Z0        O100 endif   O101 if [#<_tool_number> EQ 2]     G53 G0 X[#<_T2_X>] Y[#<_Y_POS>] (Move to position for T2)   O101 endif   O102 if [#<_tool_number> EQ 3]     G53 G0 X[#<_T3_X>] Y[#<_Y_POS>] (Move to position for T3)   O102 endif O<simple_atc_tk> endsub M2 Thanks[/b]

The likely issue here is that you turn the spindle on and in the next line you turn it off. The interpreter does not wait for the spindle to spin up to the commanded speed but moves on to the next line and the spindle is immediately turned off again.

Maybe try something like this (Note the 2 second delay before turning the spindle off)
Code:
    M04 S#<_depot_spindle_speed> G04 P2     M05   

I have no idea how long you need the spindle to turn so you will likely need to adjust the P word in the G04 command.
