Touch off after manual tool change

I have been using LinuxCNC for about an year on my mill and router for simple jobs, i want to add touch plate to offset tool length ising probe-in pin so basically

1. Want to have blank tool to zero job/touch off using G53
2. then run program on tool change 1 want to manually insert tool
3. then go to X,Y where touch plate is.
4. then tool touches plate using Z and start spindle and complete cut
5. on tool change 2 insert tool and repeat from number 3.

A lot of tutorials have little info and most links are broken or the tutorial is so complex(Windows user)

Any one that can help please ?

What do you need help with, connecting your probe switch, or writing the g-code for your probing routine?

g-code for your probing routine please

The probe routine I am using will be different from what you want. I probe on the part rather than a fixed probing station on the machine.

How you set up your file is going to depend on how your machine is set up, and how you plan to use it.

Does your machine have repeatable tool lengths? (Are tools mounted in tool holders that you swap out or are you taking tools in and out of collets with a wrench)

How do you intend to reference your touch plate?

There are a lot of little details like these that you have to work out before you can build your file.

I have a fixed probing station on (X,Y)

My first post describes the use

1. Want to have blank tool to zero job/touch off using G53
2. then run program on tool change 1 want to manually insert tool
3. then go to X,Y where touch plate is.
4. then tool touches plate using Z and start spindle and complete cut
5. on tool change 2 insert tool and repeat from number 3.

Does your machine have repeatable tool lengths ? Answer is NO

How do you intend to reference your touch plate? with the blank tool which will be replaced by touch probe in future but now will be a blank piece of mild steel with sharp point which will have repeatable tool length.

G53 is the raw machine coordinates (no offsets). You don't do any machining in G53. You can only make single line movements with it.

I think this is how I would try to set this up. I'd set up two probe files. The first one would be the reference tool probe. You would set up your first tool, run the reference tool probe routine and then run that part of the file for the first tool, then when it is time to change tools. Then you would change tools run the tool length probe routine and continue your milling.

There is an example g-code program called tool-length-probe.ngc that is included with Linuxcnc that appears to be almost exactly what you need. i would suggest breaking it up into two sub programs like so.
reference.ngcThe code for measuring the next tool (or subsequent ones)
tool-probe.ngc

You right its not G53 it is G54 where my gig is i created the two files how do i execute the subroutine ?

Do i run a MDI command ? or do integrate it somehow in the integrated in the tool change ?

Save the files in your nc_files directory or the directory specified by SUBROUTINE_PATH = in your ini file.

Do not forget to set the postion for G30. The simplest way is to move to that point then issue the MDI command G30.1

Call them by using these lines in your file where you want to reference or measure a tool in a g-code program, or with an MDI command.and

G30 is that where the touch plate, X and Y coordinates are ?

Yes
