Not exactly.
The program stops at M6 and allow to jog machine. When you push OK in
dialog box the machine resume in next line. The next line is usaly G00
with X and Y and next one is usaly G01/02/03 with Z. And Les riutine
works nice.
But if you execute the program like this:
G01 X100 Y100
M6 T1
G00 X0
G01 X-100
and you leave machine in Y<>100 then Les routine does wrong move - ruin
part or something worse.
So Les routine works in near all cases but sometime not! The user need
to be very careful when use that and check file if after M6 the all
coordinate restored with G00. Modal cordinates make here a lot of trouble!
------
If we have M0/M1 pauses inline (and some routine to make same job) the
same problem arrises.
-----
If we want to use PAUSE(ESC) and RESUME the thing is much worse.
As we hit PAUSE the machine does immidieatly decelerate and stop. The
stop is not aligned in endpoint in program but can be anywhere in line!
So if we jog here and then click resume the action is unpredicted as
machine wil skip rest of move and contunue in next line!.
So the simple KISS (keep it simple and stupid) approach is something like:
User Hit PAUSE:
machine save xyzabc... all coordinates
machine enable jog (MDI?)
user do whatever
User hit RESUME
machine does linear move to saved coordinate (not in canned cycle)
machine resume operation from point when stopped (can be in middle
of G0/1/2/3...) (not in canned cycle)
end
If coordinates are saved in #0,#1,#2.... then user can manualy restore
it (G0 X#1..) in order as want.
If motion is paused within canned (drill) cycle then I think the best
way to resume it is to ask operator if want to retry last (paused)
operation or skip it.
So if I return to question above the answer is NO.
It should be something like:
PAUSE/STOP
G30.1
jog and do whaever you like
G30
if G0/1/2/3 was paused REPEAT last (paused line) to finish it
if canned cycle was breaked decide to repeat it or resume to next (and
if resume to x clean Z before do that)
So the jog under pause is not simple but many users need/wan't that. So
I think the priority should be higher as is as workaround is possible
but wery messy and danger (for folks with grey hair) to..
So please make some effort to get solution for that problem.
Thanks
Slavko.
