You forgot the G43.

T1 M6 loads tool 1, but you need a G43 to apply the tool offsets.

Did you look at the examples in the manual?

After adding G43 to your tool line what didn't work? You need to be specific to get help. Does the tool table contain the proper diameter of the tool loaded?

I loaded your code and added G43 but I get an error on line 7 about your G10 P value being out of range.

When I comment the G10 line I get an error about lead in move too small for tool diameter but I don't know what diameter your using.

And there is no T word for G10 L1...

Fixing the G10 error I'm back to you didn't program a long enough lead in move...

Fixing the lead in move and you have moves that are too big for the tool diameter...

Switching to inside the box compensation G42 your file runs with the G10 line fixed as well...

Yes I did look at the examples in the manual.

When I add G43 to my gcode there is no tool compensation when I run the gcode.

Iam using a tool 2.34 [mm] wide. The radius of my tool is 1.17 [mm].





PS: I had no problem with tool compensation earlier, but then one day The EMC2 stoped to compensate the tool diameter. I had runed the same gcode as earlier but it didint work. I even had reinstaled the whole ubuntu with emc2 but this didint work. So maybe it is something with the Emc2 i dont know.


Thx for all reply

Now I have corrected the g10 line and it works. Thank you werry much :)

Now I will write how i solve my problem

So

G10 L1 P1 R1.17 (This line sets in the Tool Table in the first position in the tool table (L1) in the first pocket (P1) tool with the radius of 1.17).
G43 H1 (This command activates the tool table and it is important to show what kind of tool will you use in this case H1 where 1 is the first tool from the tool table)
And then
G41 or G42 after the lead move.


PS: My first problem was in the G10 command i wrote T1 and my Emc2 didnt show me an error. And my second problem was that I didnt write G43 with the H1. I write only g43 because iam stupid :P

Thanks all for your help

PS2: sorry for my english :P
