Hood thanks,

Now i will tell you that i am using my own screen that i have modified from the standard screen.

Could that be the problem. ?

I have not knowingly changed any code except the home all routine which only homed one axis.

I will try as you asked and modify the code.

OK i ran the code still the same Rapid X move

I had a box popup asking to OK a tool change

Hood

I appreciate your efforts.

I modified the code to just run one line of the code as it is posted at the beginning.

Still the same rapid X move.

The M6Start.m1s macro contains the following

  tool = GetSelectedTool()
  SetCurrentTool( tool )

I also checked all the macro's in the different folders they were all the same ?

One other thing if i jog the X axis to a different position then do a regen the Max X Limit dro will show the actual position that the X axis will rapid to

Art & Hood "Lathe & Screen4 Expert"

OK just ran the screwcutting code a couple of times

I have now set the parameter "Removed tick in remove tool offset at end of program" 

I am now changing tools via mdi line and will accept for now that the mpg error was caused again by lack of knowledge by changing tools via tool number dro

Now at the being of the thread i posted some code

Running this code i still get the X axis moving at full speed to the centre line

If i scroll the code in the code window this code this move isn't shown in the toolpath window

Looking at the limits dro's it shows the X axis to be - 1.525
                                                                       + 24.3950

Now when the code runs the X moves at high speed from X60 to X24.4 then moves back to where it is supposed to be X60 and from then on it runs as it is coded

Is this what i should be expecting ?

I am currently having a problem with tool changing in another thread.
I used my desktop to eliminate the computer part of the equation which it did.

My desktop currently runs with the parallel port fine.

Using it with the SS hooked into the slow USB port it ran out of data, so be warned.

Art

Thanks i will try to find that setting and check it.

I will also change tools from the mdi line from now on.

I have become scared of this machine the last thing i want to see is the tool driving into the chuck

Hood & Art thanks for the help

So far the mpg problem has happened once as i say a completely new install so i haven't knowingly changed any macros.

My main concern is the code i have pasted

It is a screwcutting code it produced a perfect thread i have only shown the beginning and the end to keep the size down.

To run the code i do the following

I change to tool 05 manually

Set the Z Zero position

I run the code "perfect thread"

Now herein lies the problem at the end of the run

The tool dro displays 05 but the axis dro's display the offsets for tool one. This is what was so frustrating finding this problem. How do i know

Because if i now change the tool dro to 01 the axis dro's do not change But if i change them back to 05 the axis dro's change back to the correct position that was commanded in the gcode "N730 X60. N740 Z50."

I did make a video of this but cannot upload it anywhere as it is 3Mb

Now at the end of my code i have a G50 could this be making the problem

Thanks

ART,
BTW: For excitement all you have to do is forget to do a reset back to G94 after threading, dam a trueing cut
 can realy move fast.                       

Rich a line at the beginning of all your code to set the correct operation is the way to go check my toolchanging problem thread again for an example.

This is done in the post processor in my case.
