hello everyone
currently Im trying to optimize very short lathe G code
total time 40 seconds then a bar puller is used to continue again and repeated many times
in that G code I have several times tool change and several times coolant on/off
I noticed that tool change and M8/M9 commands delay slightly but when many times used cause significant delay
I think currently I loose about 5-6 seconds total,  which is 10-15% time waste, how to avoid that delay?
thanks

Hi nik,
look if you have set a delay in Config > Ports and Pins > Spindle Seup > Fllood Mist Control
If that is set to 0 i have no delay here.
The delay regarding the toolchange depends on your Setup ( toolchange macro )

hi
it is already zero there but still have a delay probably 0.3-0.4 seconds or so
I forgot to mention - the spindle is step/dir control if that make any difference
any other ideas?
thanks

Hi,
can you attach your G code.

Alex

it is on another PC
but here is something similar to show the problem

M3 S3000
G0 Z20
T0606  ;on that line I can notice a little pause
X10
Z-5
M8       ; pause again
G1 X9 F500
Z-20
X8
Z15
M9      ; pause again
G0 X10
Z20

ok, need more input.
Attach your xml and M06start Macro please.

Alex

here are both files attached
renamed because original name unable to upload
I didnt made any changes to any files
original mach3 R3.043.022 as downloaded
newer versions do not work on that motherboard so I stick to this one

PC is pentium 4 1.7 ghz 512 ram asus motherboard
windows XP installed with all optimizations to run mach3

In later versions of mach3 a Run delay crept in concerning Mcodes.

Just a thought, (;-) TP

where is set that delay? can I change it somehow?

nik,
No M8 / M9 delay here in ver. .062 so far i can see.
The toolchange Macro you posted has no toolchange content.
