Identical tool number assigned to two different tools-creates problem for tool change

[R-Ronald]

I created a simple model in Fusion and build two tool paths.

1. A facing operation with a 9.6mm diameter indexed end mill
2. A 2d adaptive clearing operation to partially mill some slots

When I run PostProcessAll, I get gcode with both tools as "T1":

(1 Setup1) (T1 D=9.6 CR=0 - ZMIN=-4.05 - flat end mill) (T1 D=4 CR=0 - ZMIN=-13.05 - flat end mill) <snip:

(Face1) N35 T1 M6

There are no other tool change commands in the file. Thus, the 2d-adative operation will try and use the wrong tool. For a workaround, I believe that I can just insert a "M6 T2" in the line after the (2D Adaptive2) comment that marks the start of the 2nd operation (to force the program to pause for a tool change).

What post processor are you using? Do you have "Use individual operations" checked in PostProcessAll? What does the output from the built-in post processing look like?

What post processor are you using? Do you have "Use individual operations" checked in PostProcessAll? What does the output from the built-in post processing look like?

Post Processor is GrblHAL.

"Use Individual Operations" is checked.

The beginning of the two individually post-processed files (using GrblHAL) are:

1

(FaceOp)
(T1  D=9.6 CR=0 - ZMIN=0 - flat end mill)
N10 G90 G94
N11 G17
N12 G21
(When using Fusion 360 <snip> a Fusion 360 Subscription.)
N13 G28 G91 Z0
N14 G90

(Face1)
N15 T1 M6
N16 S18000 M3
N17 G4 P2
N18 G54

and #2

(2dadaptive)
(T1  D=4 CR=0 - ZMIN=-8 - flat end mill)
N10 G90 G94
N11 G17
N12 G21
(When using Fusion <snip>  with a Fusion 360 Subscription.)
N13 G28 G91 Z0
N14 G90

(2D Adaptive2)
N15 T1 M6
N16 S24000 M3
N17 G4 P2

Using the default Grbl/grbl post procesor, I get:

1

(test3)
(T1 D=9.6 CR=0 - ZMIN=0 - flat end mill)
G90 G94
G17
G21

and #2

(test2)
(T1 D=4 CR=0 - ZMIN=-8 - flat end mill)
G90 G94
G17
G21

Clearly PostProcessAll is working perfectly -- you've asked for tool #1 for both operations and that's what you're getting. If you want to change tools, you must give them different tool numbers in your tool library. If you had a paid subscription to F360 and didn't need to check the "Use individual operations", you'd get exactly the same thing.

Thanks. I should have realized that the user controls the tool number. Until I saw your second sentence, I thought that the post-processors assigned a number. But it's obvious now. I'll go thru my tools and change their numbers.
