Tutorial, step by step, for Auto Tool Measurement

I LinuxCNC, i have my small CNC and i have a number of tools.
Now i have the need to realize the machining with different tools and i homemade 2 sensors connected to the input PROBE-IN, one mobile, the 1.33 mm thick, and a fixed, positioned at X741 Y102 coordinates.

I can manually reset the workpiece or the tool relative to the fixed sensor.

But how can i automate the tool zero with respect to the workpiece?

Hey

Does anyone have idea why my machine doesn't care of the "Current Z length",
I'm able to use this example config to measure the tool height, but the machine goes as deep as g-code says, without any matter how long the tool is.

I make first tool measurement with "reference tool" button pressed and second tool measurement unpressed, but second tool goes too deep, like it would be as long as reference tool.

Thx for fast reply.

There is g43 in code, but i found out that if there is allready g43 in the "Active g-codes:" -window, the new G43 turns it to G49 and doesn't allow to turn it on again. G43 comes back in active after re-entering "t4 m6" to MDI and going through the lenght measurement.
If i manually enter to MDI new z position it works, but if i enter g43 z100 then it turns g49 mode, and goes to "absolute" value.

Use g49g53z0 to return before the tool change.

Or g49
G91g28z0

You should cancel the offset before Channing tools.

I haven't used the tool offset yet on mine because I'm waiting for my r8-er32 holders to come but on some controls like even the fanuc a g54 value affects the tool height input.

Where is g54 value?is it the amount you are off

Hi

I think that the measurent function is ok, because its the same which comes with the Linuxcnc and the tool lenght what it shows are correct.

It just change the G43 mode to G49, if the code is containing another G43 when it is allready on.

Ok, i got it working - well atleast for my current needs

Thx for Leon82, i put G49 to manual_change.ngc subroutine.

But the problem was still that every new G43 cancelled previous G43 - So i edited the Autodesk inventor Cam postscript according to this
forums.autodesk.com/t5/fusion-360-comput...om-post/td-p/7168904 and it removed all g43 from codes, because that subroutine will turn those G43 on everytime it runs.

and now it goes through 5 tool change and measurement between.

Thx for all of your help

Hey

Could you edit your answer that:
-you allso need to update python paths to ini file, and probe location etc ...

BR. some clever one who just spent 10h fighthing with the system and then looked down of the example ini file
