Did you get a chance to test the code?

I’ll check it this week. Had family member in the hospital etc and haven’t been able to get to my maker space.

Hi,

I hope this is the correct place for some testing feedback.
Reading the documentation I would have expected, that in "Auto"-mode after changing the tool manually behaves as follows:
1) Rapid move in X and Y to position defined in the INI’s [VERSA_TOOLSETTER] X and Y
2)Rapid move down in Z to position defined in the INI’s [VERSA_TOOLSETTER] Z
3)Probe down in Z to maximum defined in the INI’s [VERSA_TOOLSETTER] MAXPROBE

However Step 2 is happening at search-velocity rather then rapid.

Besides that working perfectly for me so far :)

I think you are speaking of the auto probe tool tool change.
Yes looks like the program qt_auto_probe_tool.ngc uses search velocity.
relevant code:
G53 G0 X[#<_ini[VERSA_TOOLSETTER]X>] Y[#<_ini[VERSA_TOOLSETTER]Y>]
F #<_hal[qtversaprobe.searchvel]>
G53 G1 Z[#<_ini[VERSA_TOOLSETTER]Z>]

you could change it to:
G53 G0 X[#<_ini[VERSA_TOOLSETTER]X>] Y[#<_ini[VERSA_TOOLSETTER]Y>]
G53 G0 Z[#<_ini[VERSA_TOOLSETTER]Z>]

Thanks for your help, that indeed fixed it.

I am completely new to LinuxCNC, so sorry if I am not asking the correct questions, since I don't fully understand yet, how all the parts interact.

Maybe you are also able to assist with another thing:
My toolsetter has an 8 mm diameter, but my facemill has 10mm diameter and needs to be measured at the tips. I have seen some python-code here on the forum, that is applying an x-offset for this use-case, but that seems not to be part of the "stock"-installation-auto-probe-tool-change?
Any advice on how to activate that would be appreciated.

Yes I have done some work on probing a tool and setting the tooltable. In that case diameter offsetting was added.

You could probably add this to auto probe ngc program.
Parameter 5410 should give yoy the tool diameter, as set from the tool table.
Then you would offset half that diameter.

Thanks, that was the hint needed.

I have replaced:
G53 G0 X[#<_ini[VERSA_TOOLSETTER]X>] Y[#<_ini[VERSA_TOOLSETTER]Y>]
F #<_hal[qtversaprobe.searchvel]>
G53 G0 Z[#<_ini[VERSA_TOOLSETTER]Z>]

With this:
O250 if [#5410 GT [#<_ini[VERSA_TOOLSETTER]DIAMETER>-1]]
    #<toolprobe_x_offset> = [#5410/2]
O250 else
    #<toolprobe_x_offset> = 0
O250 endif

G53 G0 X[#<_ini[VERSA_TOOLSETTER]X>+#<toolprobe_x_offset>] Y[#<_ini[VERSA_TOOLSETTER]Y>]
F #<_hal[qtversaprobe.searchvel]>
G53 G0 Z[#<_ini[VERSA_TOOLSETTER]Z>]
