The maximum number of tools is currently hard coded and limited to 56 (see https://github.com/machinekit/machinekit/blob/master/src/emc/nml_intf/emctool.h#L23). Would it make any problems to raise the number of supported tools to 100?

See this from someone you know in US 😄

It would be worth chasing down the whole thread, Andy Pugh looked at the whole tool table issue some while back with a view to changing it to SQL or similar.

Looks like the only real issue is ensuring the buffers are large enough to accommodate the increased structure size.

quoting from LinuxCNC/linuxcnc#411

to increase the tool amount you need to edit two files, i.e. 256 tools:

/configs/common/linuxcnc.nml
change:
emcStatus from 16384 to 33792
toolSts from 8192 to 33792

and /src/emc/nml_intf/emctool.h
CANON_POCKETS_MAX to 257
