My fault. In the installation instructions did not make important lines in my-mill-postgui.hal:
net tool-change            probe.toolchange-change    <=   iocontrol.0.tool-change 
net tool-changed           probe.toolchange-changed   <=   iocontrol.0.tool-changed
net tool-prep-number       probe.toolchange-number    <=   iocontrol.0.tool-prep-number
Changed (".hal correction for tool change", "del "%" from macros")

Hi Verser, thanks for the awesome work!

I have made the changes and it does the tool change without freezing.
Now after I do an M6 T1 G43 i get an info message sayin "No tool measurement. Please take care of the entry in the tool table."

In order to use the Remap M6, I've put the probe in the spindle and measured the height of the TS Height and it got updated.
Then I've loaded a tool using either M6 T1 (tried with and without G43).
The table moves to the coordinates of the tool setter, it goes down until it touches and then I get this error:
"Probe is already tripped when starting G38.2 or G38.3 move" and it stops there...
Any idea how should I fix this?

Does anybody know if both Probe Screen V2 for LinuxCNC and gmoccapy probing can be installed at the same time?

I run both gmoccapy and Probe v2.
This works ok, except for my issue/question on the Remap command. See my posts above,
Apparently that is being worked upon.

Hi, on problem solved another apears :)

with the probe screen I can touch off the workpiece, set the zero by auto measurement. The Touch sensor height measurment seams ok.

Then I start my gcode and the M6 manual tool change starts, the tool height measurement works but after the measurement the G54 origin is automatically moved outside my maschine coordinate ? See the picture.

I used a simpler manual tool change height measurement on my old linuxcnc machine. But i did not work with the G10 L20/L2 offset like the Probe Screen V2. I only used the G43.1 to compensate the different tool heights.

Any idea?

Maybe the reason is related to my g-code creator:

%
( MCV-OP ) (02-MAR-2019)
(SUBROUTINES: O2 .. O0)
G90 G17
G80 G49 G40
G54
G53 G0 Z-20
G90

M01
M6 T1

Thanks

There is another issue that I think its a bug of the probe screen.
I had the same behavior randomly when probing the X+ --> |
If I restart linuxcnc and I try again, it works for a while..but it very inconveninent to restart linuxcnc & rehome each time I need to probe.
Also I've noticed that workpiece height is not saved into that .pref file, each time I restart linuxcnc it gets set to zero.

Please let me know if I'm missing something here.

probe screen V2 is not that finished at this time still workaround to do

the inconvenience comes if G92 jumps in and does a side calculation
TRY if this happens G92.1 in MDI
and probe again

also you may be in G91 mode already
use G90 MDI to test behavior

I have noticed that it seems to work if I lower the feedrate at 50%.
Don't know yet if it's a coincidence or not, still have to figure it out.
What I have noticed is that the inside diameter measurement is not accurate or repeatable.
I have measured a ballbearing with inside diameter of 15mm.
The values I got for diameter were 15,21
I have measured the stylus ruby ball and its 1.99mm
and also in the video above, I was measuring a 10mm bore and I got 10.2114.
Any idea where can this come from?
I have made jog tests with a plunge test indicator, and the movements are correct and the backlash is around 0.01.
Also I've multiple X+ and X- measurements and the values are repeatable within 0,01 range.
Any idea where can the 0.2 error come from?
