hi
i thought I could save wear and tear on the spindle motor by keeping it on for the 500 cycles
to avoid spindle stop, use something like this :
Code:
spindle running
G00 Z_up
G00 Y_bring_table_near_door
/... or M01 (*1)
G00 Y_send_table_at_work_position
G00 Z_down
(
*1
search a parameter inside the machine, that won't stop the spindle during optional stop
)
Turned out that auto spindle turn off and then a simple cycle start worked best
also a ctr capability will save some time :
Code:
G00 Z_up
G00 Z_down S M03 ( rpm and linear travel, both of them, begin at same moment )
Things I learned from this job was a slow constant downward pressure worked 10x better than peck drilling
the truth is in between : somehow, you have to change the peck distance and the cutting feeds as you go deeper, so to keep ( almost ) same torque on the spindle, and also the chips to come out; it may be needed, after a certain depth, to retreat the drill at a much greater clearance in front of the part, so to have time to throw the chips ... decisions about what to do, where to change, etc, requires to inspect the Zand/orS axis load diagram

is needed to mess with the keylocks, so to be able to open the cabinet door at any time; i have done this, and it was ok, but i started to worry when someone else was working on the machine, so, i told that person to open the door only when blue light is on ( thus machine is in stop state ) / kindly
