Manual Tool Change again?

andypugh: It is a little too much for me. I'm still learning LinuxCNC.

I incorrectly thought that AXIS preview red lines will show only job from G-code file.

Do hal_manualtoolchange file modification would be the best option here?
Eg. Instead of embedding the JOG during the display shows "replace the tool number...", just run some subroutines or g-code in background?
If not used REMAP function, this should not impact on the value of boundry lines.

The red dotted box shows the machine physical limits.

Is your problem that the G-code preview shows the toolchange moves and you don't want that?

Someone before wrote "red" but really this lines is pink, and all time is about "Program Extents"

Yes. If i use REMAP for manual tool changing and auto probe tool (im using subroutine), preview will change Extents, i dont want that. I'v checked (AXIS,show)/(AXIS,hide) functions, and included them into subroutine file, but it must be for something else.

The extents are calculated when the G-code is loaded.
It might be possible to exit your remapped subs before any movement occurs during the preview stage.

Try an IF around the remap moves:

O100 IF [#<_task> EQ 1]
...
O100 ENDIF

I'v checked it on sim machine, and it works. THX Will check on my real one.

Hi.
I have wondering why my tool change probe and scripts, somethimes crash my machine.
I was blind (noob also) and didnt recognise this command: G43 Z15. H0 :blush:
Its in every my GCode file, after load new one and run it, it reset my tool Z offset, and calculations to next being reset.

Im using HSM Express post processor, there i should search for answer (modify)?
Anyone had same problems?

Edit: I made changes in postprocesor. It seems like its not ready to handle manual tool change, strange.
