TOOL TABLE SETUP OR POST PROCESSOR

TOOL TABLE SETUP OR POST PROCESSOR was created by Doug Crews
Hello,
I'm wondering if I missed something during configuration. I'm running Axis GUI and using code from the Fusion 360 post. The code looks right but I noticed cutter compensation is not working, Axis displays "0" cutter diameter at bottom of the screen. I have tool diameter in tool table and the right tool number.

I am able to get the program to work by inserting G10 L1 P1 R*** and it shows the diameter in Axis at the bottom of the screen and even updates the tool table to the R value. Is there some noob thing I've missed along the way so i don't have to use the G10 L1 in the part program?

Thanks

the G43 Hx x=Toolnumber
and inside Gcode G41Dx or G42Dx
Code:
G17 G21 G54 G61 G90 G40 G80 G10 L1 P1 Z0 R3.5 (set tool 1 Zoffset R Radius) G10 L1 P2 Z0 R3.2 (set tool 2 Zoffset R Radius) G10 L1 P3 Z0 R3.05 (set tool 3 Zoffset R Radius) G10 L1 P4 Z0 R2.98 (set tool 4 Zoffset R Radius) G0 X45 y15 z20 G0 X45 y15 G0 Z2 G1 Z-1 F200 G42 D1 o101 sub G1 x50 y0 x0 y15 G0 z5 G40 o101 endsub (end contur) o101 call G0 X45 y15 G0 Z2 G1 Z-1 F200 G42 D2 o101 call G0 X45 y15 G0 Z2 G1 Z-1 F200 G42 D3 o101 call G0 X45 y15 G0 Z2 G1 Z-1 F200 G42 D4 o101 call G0 Z20 m2

Here is the post out of fusion. Looks different than yours. Among other things its missing the D's in the G41&42's. I'm using the linunuxcnc post that is in the native Fusion list.


Code:

Thanks for showing an example. Did you modify the stock post processor?

If you type T4 M6 G43 in the MDI window, does it change the tool to Tool#4 and display the diameter and length offset as defined in the tool table in the status bar?
Attached some screen grabs. And do you have the "manual tool changer" set up in Linux CNC too? You get a brief splash screen on startup, and then a dialog requesting you to change tool when the M6 code is invoked.

See linuxcnc.org/docs/2.7/html/gcode/tool-compensation.html and linuxcnc.org/docs/2.7/html/gui/axis.html#_manual_tool_change

This is not the Right post for CRC on EMC
there is no G41 inside
and no Tool Diameter set as D inside your gcode

Thanks for the the screen shots and examples. There were two things hanging me up.

First:
I was commenting out entire lines that had z-moves.
The solution…stop playing with x&Y and get Z going! So I did.

Second:
It was what my gut was telling me. Noob incident.

I “ASSumed” when I changed cutter diameter then saved and quit the tool table it updated the control. I somehow kept missing the selection just under “edit tool table” which is “RE-LOAD tool table” problem solved.

Thanks for all help and suggestions you all are great.
