Limit to number of tools in tool table

Hi
I also wanted to change one of my CNC milling machinges to linuxCNC, but with the limation of tools to 56, I have no chance. For the milling machine I have about 150 tools.
I tried the above link, changed the two files with no resultat. T60 M6 G43 will give a error message.
Also the limitation that a tool must always have a specific pocket number - never the same - it is difficult to work with tool turret. If you have a carousel with 8 places, but a you have more than these 8 tools - what can we do? IMO it is normal, that a tool number 1 and a tool number 9 could have the same pockets.

Has anybody an idea? It would be great.

Tool table limit (257 instead of 56)
By default the tool limit of linuxcnc is 56 tools. This is normally to low (after all we are not working with a >10 year controller). To solve this two changes must be made in the source code as described below:

linuxcnc.nml
The file linuxcnc.nml is located at:

"your linuxcnc-dev"/configs/common/linuxcnc.nml

Two changes should be made:

Replace the value 16384 of line number 10:

B emcStatus SHMEM localhost 16384 0 0 2 16 1002 TCP=5005 xdr

to 33792

B emcStatus SHMEM localhost 33792 0 0 2 16 1002 TCP=5005 xdr


and replace the value 8192 of line number 15:

B toolSts SHMEM localhost 8192 0 0 5 16 1005 TCP=5005 xdr

to 33792

B toolSts SHMEM localhost 33792 0 0 5 16 1005 TCP=5005 xdr


emctool.h
The file emctool.h is located at:

"your linuxcnc-dev"/src/emc/nml_intf/emctool.h

One change should be made:

Replace the value 56 of line number 23:

define CANON_POCKETS_MAX 56

to 257

define CANON_POCKETS_MAX 257


Compile and have fun with more tools!

Hello, where can I find these files for editing?
it is not in the machine settings directory.

checked the changes from here github.com/LinuxCNC/linuxcnc/issues/411

but this is a very short and simple test))
Has anyone already tried this at work?

one thing that i would really appreciate is to define a tool as a touch probe. This way the tool will be only allowed to rotate when orienting the spindle. M3/M4 commands will be ignored. Also the maximum feedrate should be limited to a definable value.

Other useful parameters would be:

Tool edge radius (0 or more, float)
Delta length (extra tool length offset - negative, 0 or positive - float)
Delta radius (extra tool radius offset - negative, 0 or positive - float)
Delta edge radius (extra tool edge radius offset - negative, 0 or positive - float)
orienting angle (0-359.999 - float)
Tool locked (used with breakage detection - 0 or 1)
number of cutting edges (0 or positive)
length offset and radius offset (for measuring length and radius - negative, 0 or positive - float)
lbreak and rbreak (for tool breakage detection - negative, 0 or positive - float)
Nmax (maximum rotation speed - 0 or positive)

and maybe to be allowed to define tools like this: T1.1 (still the same physical tool but other definitions)

my wishlist

There was some work on using a database for the tool table.
This would allow arbitrary info to be added to the tooltable.
This would be a first step to what you want.

Andy started it but got discouraged by lack of support IIRC.

(but does it really belong in the "tool" category?)

yes, at least what i know Heidenhain does this. This prevents the tool to go above the set max-rpm when automatically calculating the rpm based on the tool diameter and cutting speed (VC in Metric and SFM in Imperial)
