Limit to number of tools in tool table

Is there a limit to the number of tools in the tool table? I was under the impression only 99 tools were allowed. However I can't find reference to that now. I recently saw in another post that someone had a tool number T9999.

Just wondering if there is a limit?

Assuming your talking about a recent version of LinuxCNC...

You can have a total of 56 tools, but the tool numbers can be as big as you want.

This brings up another question. Why are we limited to 56 tools? I would like to have a single tool table that is consistent from Fusion 360 to LinuxCNC. However with a limit of 56 tools I will have to change my LinuxCNC tool table if my required tools change. This is a pain.

Does anyone know the reason behind the limit of 56 tools in the table? Is this something that could be changed?

Note I have not ran into the limit yet but I am sure I will shortly. Different drill sizes are the real culprit.

Yes, the tool data is passed around between the different modules in a fixed size structure that only has room for 56 tools.

It's crazy, and I actually did a lot of work to fix it and put the tool data in an SQL database. But it was widely ignored.

it's the andypugh/tooltable branch here: git.linuxcnc.org/gitweb?p=linuxcnc.git;a=heads

Andy i publicly vote for this to be put into the mainstream code base . it really should be there.
their are many users with big tool tables myself included

I vote for this also.

I have reached the 56 tools limit on 2 machines, and that is simply annoying :side:

And when this limit was reached, find that the number of tools in the tool table is the problem it's kind of difficult, linuxcnc don´t even starts so the tool table has to be edited manually.

My vote is for a SQL database solution, that permits some flexibility on the future. Some triggers that update automatically the tools offsets if changed on the database should be great.

Commit it to master so it can get some testing. People using master expect it to break from time to time.

Andy:

When i get no response such as you did - I take it as a go-ahead.
I announce that i'm going to add it to master unless i hear a good reason not too.
and after that I will commit it to master. once it's in master if there is a real reason not to have it there,
devs will be more forward.

It has happened a few times for me and wasn't negative.
And I vote for your work on tool table too.
and for JA branch

In fact I think we should peel off a 2.8 branch off master now then add JA right away.
It's the only way it will get added any time reasonable.
