G54 is changed in Z when using M6 tool change

[TH-CRAFTS]

Hi. I have an issue with my ATC router.
I would be very grateful if someone can help me out.
I have been strugling with this for some time and I'm not (yet) capable of understanding the M6 script.

Background:
I use Fusion 360 for CAD/CAM and Mach3 to run my router.

I have set the G54 and every thing works fine till the tool change.
The M6 is activated and the tool is changed and then at the end of M6 the G54 is changed in Z!

It seems like something in the M6 script is taking the Z position of the machine exactly when it is leaving the tool change position and puts in that figure in to the G54 Z.

I provide the M6 script, can someone please have a look on it?

Regards Tomas

You don't have to use anything in the G54Z0 is the norm unless you have set a master Tool and entered it in the G54Z----, a G43Z----H2(=T2) is where the Tool offsets are kept

T2M6 (Tool number and Tool change call)

G54 (=X / Y Position)

S12000

G0Z---- (This is only needed to clear your work if the M6 is not working correctly, or the Tool change is lower than your work)

G90G0X4Y4. ( X/Y move to wherever it is set in start position in your Program)

G43Z.1H2 (Tool OffSet Call and Z axis move above the part)

Hi and thanks for your reply!

Due to short experience in code I have an issue following you and I'm worried that I do some kind of basic error.

Can I just tell you how I set up the tool length and the G54?

T1 I set to a fake length lets say H50mm that I enter in to the tool table
With that tool in the spindle I touch the top of my part and set the G54. Typically my machine Z-position can be -100 and the G54Z will hence be -150

Then I put in T2 maually in the spindle, and remember to switch to T2 in Mach3. I touch my part and store the T2 H-value in to the tool table. If T2 is 10mm longer than T1, the T2H will be 60.

So what happens when I run the program below is that T1 works fine, but at line . N165-N175, when T2 goes out of the tool rack and start to spin, the G54 Z is changed to the machine position at that moment plus the tool compensation. Typically -200-150=-350.

Can you understand why? You say in your comment;

G0Z---- (This is only needed to clear your work if the M6 is not working correctly, or the Tool change is lower than your work)

The tool change is lower than my work.

Im very happy for your supprt. Regards

Because you are setting each tool to the top of your work / job you do not want to be using a dummy tool for G54 your G54 you should leave at Z= (0) then set each tool to the top of your part, this will then be in the tool 0ffSet settings

So, if you see in you posted code G43 Z15. H1 this then sets your tool (1) to the correct 0ffSet from the tool 0ffSet page and the same will happen for each tool you use

You have a G43Z15H1 this gets the information from what you entered in the tool 0ffSet page

Your second Tool G43 Z15. H2 gets the stored information from what you entered in the tool 0ffSet page

The method you are trying to do is normally used with a Tool Setter
