Gmoccapy Toollength sensor routine stops sometimes was created by pe8art

Dear All.

I use Gmoccapy for my CNC-Router.
I use the macro below to measure my tool height.
Switching between tools it for some tools stops in the middle of traveling to the probe.
For others it doesn't, does anyone have an idea?

Best regards from The Netherlands.

stops in the middle of traveling to the probe.

Which move do you mean?
- XY move (G53 X#1801 Y#1802 )
- Z move (G53 Z#1800 )
- the actual probing move (G38.2 Z-60 F500 )

It stops doing this move.

- XY move (G53 X#1801 Y#1802 )

For testing try inserting a queue buster command to halt the read ahead until the move is finished:

Code:

G53 Z#1702 (Wechsel Z Position)
G53 X#1700 Y#1701 (Wechsel XY Position)
M66 E0 L0 (Stop read-ahead and wait for code execution to catch up)

M6 T#<_selected_tool>

Also try and start your config from terminal (note the minux+letter'L') and check for messages when the routine fails.

Code:

linuxcnc -l

I tried the command but no different effect.

The Terminal spits out " 3 2 " every time regardless if it stops in the move or not.
It seems to be stopping at a specific sequence from tool to tool.
Some of the work ok some don't.
I have tried changing diameter of the tool for to no avail.

Not sure what's going on but you might want to insert some debugging statements:

Code:

M66 E0 L0 (Stop read-ahead and wait for code execution to catch up)
(DEBUG, 1702: #1702)
G53 Z#1702 (Wechsel Z Position)
M66 E0 L0 (Stop read-ahead and wait for code execution to catch up)
(DEBUG, 1700: #1700 1701: #1701 )
G53 X#1700 Y#1701 (Wechsel XY Position)
M66 E0 L0 (Stop read-ahead and wait for code execution to catch up)

M6 T#<_selected_tool>

Also make sure you don't have X or Y offsets in your tool table.

I included the debug in the file ( and added some more to see where its stops. )
It seems to stop between :
M6 T#<_selected_tool>
And
G53 X#1801 Y#1802 (Taster Position)

Oh, apologies I was looking at the wrong move.

Maybe try this:

Code:

G53 X#1700 Y#1701        (Wechsel XY Position)
M6 T#<_selected_tool>
M66 E0 L0 (Stop read-ahead and wait for code execution to catch up)
(DEBUG, 1801: #1801 1802: #1802 )
G53 X#1801 Y#1802       (Taster Position)
G53 Z#1800                (Sichere Z Position)
M66 E0 L0 (Stop read-ahead and wait for code execution to catch up)

I have included your code and added some extra debug comments.Consistently it stop changing from tool 1 to 2.
The code I added is:

Code:

M6 T#<_selected_tool>
(DEBUG, M6: #<_selected_tool> )
M66 E0 L0 (Stop read-ahead and wait for code execution to catch up)
(DEBUG, 1801: #1801 1802: #1802 )
G53 X#1801 Y#1802       (Taster Position)
(DEBUG, before Z#1800)
G53 Z#1800                (Sichere Z Position)
M66 E0 L0 (Stop read-ahead and wait for code execution to catch up)
(DEBUG,Before G43)
G43.1 Z0                (TLO reset)
(DEBUG, before G91)
G91
(DEBUG, before G38.2)
G38.2 Z-60  F500        (messen grob)

Only other thing I can think of is to add 'G0' to those 'G53' lines.
