Disable tool table?
I'll begin with a few lines of back story; about a week back our old computer running a really old build of linuxcnc finally threw in the towel. We replaced the machine with a new one and installed the latest version of Linuxcnc. To our joy, pretty much everything seemed to be spot on and working as before if not better.
Until yesterday.
I was doing some contouring and when I switched to drilling operations I coldn't load the .ngc. Linuxcnc threw the error: "Requested tool X not found in tooltable" and flat out refused to load the toolpaths.
Now, i've been digging around a good part of last night and this morning to find an override or similar solution to avoind checking the tool numbers in the g-code towards the tool table. It's a really small machine, all toolchanges are manual, so no need for Linuxcnc to keep track of our tools, this is done in CAM.
I just want to mill my things and work like we used to, but nothing gets past the tool table and I don't have the time or the data to enter every odd tool I use into linuxcnc.
Can I turn this 'feature' off? Is there anything I can do in postprocessing to avoid this? I use Fusion 360 for CAD/CAM.
Very thankful for any assistance, I really need to make some chips fly!

Is the problem that you have legacy G-code that uses tool changes?
How many tools are you talking about? It might not be as difficult to create the required tool table entries as you think.

As for legacy, I have selected preloadTool and writeTool as 'no' in the post processor. Though I'm too much of a novice to really know the implications of this. I have also tried with stock settings, which turns the options to 'yes', no difference in results.
As for creating the tool table; it's a machine that is used not only by me and other members of the makerspace which houses the mill may well bring their own tools, I wouldn't wanna mess up their work which is why I'd be happy if I could just run everything from CAM.

It should be. But I am curious about what changed to make your previous (presumably working) tool table stop working.Would it be possible to create a dummy table with random tools in linuxcnc and just run like usual?
Is Fusion inserting M6 and T commands? G43?As for legacy, I have selected preloadTool and writeTool as 'no' in the post processor.
Fusion seems to have a tool-table per job (which is actually frustrating to me)As for creating the tool table; it's a machine that is used not only by me and other members of the makerspace which houses the mill may well bring their own tools, I wouldn't wanna mess up their work which is why I'd be happy if I could just run everything from CAM.
I think you either need to have a tool table and use it, or not have a tool table and eliminate tool-change commands from the G-code.

I didn't touch the tool table, it stopped working from one file to another. And when loading the first g-code it didn't work either.It should be. But I am curious about what changed to make your previous (presumably working) tool table stop working.
Yes, line 8 has both the M6 and T command, I have edited that out and tried to run it, but it just skipped a few lines and complained about a later line instead. I'm not that the machine at the moment and I can't remember the specific line. I'll upload the g-code attached to this post and try in an hour when I'm in the shop.Is Fusion inserting M6 and T commands? G43?
I'll try to use a dummy table then, I'll report back with any resultsI think you either need to have a tool table and use it, or not have a tool table and eliminate tool-change commands from the G-code.

Thank you for your help!

this usually happens if for argument you call tool 4 and theirs only 3 in the table
when using a cam program it's best to use the linuxcnc tool table for wear offsets only , and let the cam side do it's job

just add dummy entrys to cover the tools +1

I manually removed M6, T commands and G43 from my g-code and it finally ran! Sadly using dummy entries did nothing to prevent the error... Manually editing every g-code will work in the short term, but if you or anyone else has any ideas how to solve this, either in CAM/Post or in LinCNC I'd extremely grateful!
Anyways, thanks for all the help, any additional input is valuable!

Did you edit the tool table in the tool table editor?
Did you add tools with numbers that corresponded to the ones called out in the G-code?

so if you have 9 tools then you need 10 entrys .
post your tooltable
