Thanks Les, This seems to do the job. The only thing I noticed and
this was also true with the distribution version is that the continue
message does not always appear on the first tool. It does for all later
tools though, and it is easy enough to overcome this by simply making

Hi Hubert,
Thanks for testing it. I think the reason why it is missing the first
tool change is that you have already selected that tool in MDI. If you
hit an M06 for a tool that is already in the spindle, EMC ignores it.
In it's current form it is too easy to get out of sync with Axis. To be
Some controls have a 'teach mode' that records your jogs. You can then
replay the jogs either forwards or backwards. This is pretty much the
same as you describe. Things get a bit more complicated when you are
using MPG jogging, especially if you have multiple MPGs. In that case

They have a front panel button called Recover.
When pressed the first time it sets the feedhold

Pondering this to myself I came to much the same solution.

I believe in an earlier post that you had created some changes that
would allow the use of MDI but you couldn't completely test right now.
I would like to try them as I have several parts that I am ready to

Leslie,
Having a tool presetter or not,at some point in time you have to
inform the control how long the next the tool is.So if you go at a one off job
like you have tool holders but really dont, I dont think it will
make much difference time wise.After the first tool you would go to a tool
Just spent a couple of hours playing around and have this pretty much
working. I now have a modified version of the manual tool change script
that stops the machine when you hit a tool change. After you have jogged
and run any MDI, clicking on continue restarts the machine on the next
line.
Leslie,

intrest in this then great.

Hi Terry,
A 'tool check' type function would be very useful but it doesn't look
like anyone is likely to have enough time to put into this in the
foreseeable future. I would like to have a go but I simply don't have
the time to invest in learning the inner workings of the trajectory planner.

One way to approach this would be to use HAL to add a position offset to
each joint. Normally, this would be set to zero. While paused, one could
then have jog functions that changed those offsets. That could manually
position the cutter where you wanted.
Then when you are done, use the jog

Does two jogs in the same direction count as two or
does the change of axis make the next one of the three?
Either way it sounds cool.

Exactly. Your code needs to be aware you are likely to do a tool change.
After the tool change, the code has to move to the safe Z clearance
plane then do a G0 move to the cut start. This is pretty much what you
would do after an automatic tool change anyway.
I have trouble understanding why
Hi Terry,
I have had this ability on machines and only used it once or twice
I wouldnt call that a major drawback.
Well thought out programs shouldnt need to be stopped.
That depends on how you work. If you are producing 100,000 widgets or
you have a set of pre-set tools in holders then

Is there anyway to use MDI during a program run. I would like to be
able to move the work and adjust the zero of the Z-axis during a tool

Hubert,
there is also the option of integrating a tool length sensor.
With the first tool set the home position of the Z-axis and use the tool
length sensor to record a tool-sensor offset.
After changing the tool, go back to the tool length sensor and determine
the tool length, minus the offset
