The Fusion grbl post processor inserts an M6 command on every tool including the initial tool path. I know there are other grbl posts that have the option to not insert an M6 on the first tool path but I would prefer to stick with the stock one. It would be nice if there was an option under the TLS settings to ignore the first M6 command to reduce the time not cutting in a job. I would rather not have to edit every multi-tool gcode file I generate.
@Kerryh2012, funny you bring this up. As of 1.5.5 we implemented an ignore for this first tool change due to the confusion it was causing others. If you can try it out and let us know if it’s worked out for you, that’d be great
Thanx Chris, I’ve just been removing the first tool change manually. I’d almost forgotten about it. I saw that my other issue with the AZTP with a set bit diameter is on the fix list the other day too. I called it a missing divide by 2 issue, the devs called it a double compensating issue. I found that funny. It looks like this release fixes 3 of my issues, 2 I have brought up on the forums. 1 I privately wondered why I had to probe the initial tool on the first tool change since it was the one I zeroed with. I’m looking forward to giving it a run though.

Yeah it a sense it was both since if you double compensate radius then you get diameter, and if you don’t divide diameter by two to get radius, you get diameter XD
Either way, it was all a part of a specific focus on probing for 1.5.5 so the issue should now also be fixed as of the testing I did with the team over the last couple days. Fingers crossed!
This works too but won’t not having it as a selectable option cause problems for things like the ATC?

Yes it will cause problems. For ATC application we’ll be working on a better long-term solution alongside all the other work we’re putting in to support ATC systems
Can always pad the beginning of the gcode file with G21’s as a hack. Just tested this.
