Upgraded 2.6>2.7.14, tool offset issue was created by lukepighetti
Hey all. Haven’t changed my setup except upgrading. May be a config issue.

Before: touch off with any tool, program calls a tool change, the offset stays the same. In other words, the tool offset was constant (zero?)

Now: put in a tool, touch off spoilboard, run program, asks to change the tool (the one I touched off), I click okay, it changes the offset

Even worse: touch off, set z to 0.010”, dro says it’s 0.7720”. Have to restart LinuxCNC to clear whatever offset is causing this issue.

Active gcodes when touchoff isn’t working as expected: g1,10,17,40,20,90,94,54,43,99,64,97,91.1,8
M5,9,48,53,0
F162

Alright, it appears that the default tool table has tools with offsets. Yikes! Tried deleting all the tools and now it gives me an error that a tool can’t be found in the table. In 2.6 this would fail gracefully, no? I use compensation in post processing instead of the tool table. Any insights as to best practices here? This is a cnc router with manual tool change.

Luke,

Find in the Gmoccapy directory a standard config file for a standard tool file "tool.tbl".
Try this file and if no error is displaying and the tool table will load you are on the good way !
Tool.tbl files can be fragile when modified by user !

This is inside my tool.tbl file to load plasma amp's
Code:
T1 P1 X0.0 Y0.0 Z0.0 A0.0 B0.0 C0.0 U0.0 V0.0 W0.0 D0.0 I0.0 J0.0 Q0.0 ;10 Amp T2 P2 X0.0 Y0.0 Z0.0 A0.0 B0.0 C0.0 U0.0 V0.0 W0.0 D0.0 I0.0 J0.0 Q0.0 ;25 Amps T3 P3 X0.0 Y0.0 Z0.0 A0.0 B0.0 C0.0 U0.0 V0.0 W0.0 D0.0 I0.0 J0.0 Q0.0 ;40 amp

Inside a standard Gmoccapy file you will find :
Code:

Thanks! From what I can tell I need a tool table with every possible number I will ever use with a zero z offset. Is that correct? I don’t remember having to do that in 2.6.

If you write a tool table inside of linuxcnc your output will be just like my plasma tool.tbl
It's made not by me, but by linuxcnc. B)
Have fun !

I used this tool table before for testing purposes. If i could help you with it. It's nice !
If you have no error step one is done !

Second step to do :
If you write your own new tool table in linux you will find out your offsets.

If you have T8 M8
you need that tool 8 . All other values can be 0 but with 0mm diameter you will not see a tool in preview. So better set them all f.x. to 4mm to have them visible.
