Tool Change
« on: March 04, 2018, 05:03:23 AM »
Whenever I move the spindle on my CNC-Router  to a convenient place to perform a tool change, it will return to the place where it came from in a  very slow speed.
In fact the feed speed that has last been been programmed before the tool change.
In case of drilling holes, that would in my case be 50 mm/min  (I always do the drilling very slow).
N.B. I use stanfard code fragments;
e.g. for a  tool change:
-
N1000 M06 D04 T04  (change to 4 mm in D04)
N1010 S3000 F3000
-
How do I make the spindle return more quickly ?
regards,

add a G00 plus whatever plane move

N999 G00 X__ Y__ Z__
N1000 M06 D04 T04  (change to 4 mm in D04)
N1010 S3000 F3000

That sounds logical. This should remember Mach3 that the last move before toolchange was at G00 speed.
I give it a try.
Thanks,

Wilfried.

Did it work for you?

Sorry for the very late reply, but I was not able the test any sooner.
But unfortunately it did not work. I also realized that all my subs already end with a "G00 Z25" to bring the tool to a safe height.
So the last movement before a tool change has always been a G00.
But anyway, thanks for helping.
