Hi there
Here's the problem: I am running a machine with a touchprobe( manual toolchange). If I run individual toolpaths from a group where all of the tools are labeled as T1  I have no problem...If I run all of the toolpaths as a group, I encounter a message that asks me for a preparation move which then plunges into the material after Cycle start....(ends up with a differant Z level)  Lets see if i can explaine this a bit better:

1) profile cut  12.7mm cutter
2) profile cut  12.7mm cutter
3) pocketing   11.9mm cutter
4) pocketing   11.9mm cutter
5) pocketing   11.9mm cutter
6) pocketing   11.9mm cutter
7) pocketing   11.9mm cutter
8) pocketing   11.9mm cutter
9) zlevel finish  12.7 bullnose      this is where it goes pearshaped after the touchprobe sequence!!!

Is the problem caused by the fact that I have named all the tools as T1 or is it from something else?

Can you explain what you are actually doing with the touch probe as I am not really sure what you are meaning.

Hi Hood
not sure if I'm using the right terminology here...the  probe is a tool height sensor that feeds the info back to Mach for the T1M06 macro
sorry for any unclarity on my part (I blame the heat at the moment) lol

Glen you must have different tools with different numbers

So 12.7 mm would be tool one

11.9mm would be tool two

12.7mm bullnose would be tool three

This assumes that there are only three cutters involved

I suggest you always check before running a part that the height offsets are correct

Hi there Phil
I was thinking that too...
will do a test run ASAP   but I think thats the solution

Hi Glen,

Don't suppose you could send some of your surplus heat over here could you ?. Then I could get rid of some of the brass monkeys which keep coming to my door wanting soldering jobs.  :)

Hey Tweakie!

the darn machine is still doing it!!
I'm beginning to think the problem might be with post processor I'm using in Onecnc.....
If anyone has anymore ideas I'd appreciate the assist

PS  if I run each of the tool paths separately with each one labeled as tool1 = no problem. Its only when I run the toolpaths as a group batch(if you want to call it that) that I get random start points for the next TP in line and Z depths that are not correct

Hoping everyone is doin well

Hi Glen,

To "activate" the  tool length calculation in mach you need to put:-

T1 M06
G43 L1

and for tool 2 for example
T2 M06
G43 L2

The G43 L# needs to be on a separate line to the tol number.
I had this all on one line and mach would randomly ignore the tool length.
You can "chop it off" but can't "chop it on"
