Hi Drew,

attached a brain.

Output3 = Spindle
Output4 = Coolant
Output1 = air

hope that helps

If you are meaning you entered 50 into the Z DRO

Yes.
Just tried 053. no probs there
also 066 062
looks like only 057 shows this ( here ) 

I keep 062

General Mach Discussion / Re: how to avoid T/M commands execution delay

The same thing here.
You can link a brain to an output that switch a high speed relay whitch reverses the direction.
I think there are some relays on the market that switch in a millisecond.
i doent know if that is a save operation.
A better way is to choose your tools so that they use all the same direction.

just a thought

Just gone back to 057 and used a new xml
Put in 50 mm in g54 Fixture ( the same result like G52Z50 )
When you start the code You get this: ( see picture)

Do the wizards add a G52?

No. this was only for testing.

I have the same behavior here in 057.

If I swap to 62 will the turn wizards work OK?

yes.

Hood, did you try this?

G52 Z50
... your code here

Hi Joe,
if I understand you right ( my english may be better ) I would say yes.

the delay for the T word is 0.11 sec. here not 0.16 as i said before. ( 1000 toolchanges = 110 sec.)
So far i can see there is no other way to avoid these 0.11 sec.
( only  one second for 9 tool changes !)
I think you have to deal with the M3/M4/M5 delays.

Have tried a few things and have found out the delay for the T command is also about 0.166 sec.
I doent read brains documentation, i did that learning by doing.
You can't use a LED in the Brain, because you have to turn it on from your G code with a M command and then you will have the delay.
Let the Brain " watch " for an Axis position. This works here. I activated the B axis. Tuned it to 100 Steps per Unit Max Vel  Max Accel.
You can use G10 to shift your tool without delay. ( easy if you have a gang tool lathe ) all other things have the same delay ( G52 , G54 ...)


T0101
M3 S3000
G0 Z20
G10 L1 P1 X#520 Z#521 ; shift to the next tool
X10
Z-5
G0B1      ; Coolant on
G1 X9 F500
Z-20
X8
Z15
G0B0      ; Coolant off
G0 X10
Z20
M30

or something like this

T0101
M3 S3000
G0 Z[20+#511]
X[20+#510]
Z[-5+#511]
G0B1      ; Coolant on
G1 X[9+#510] F500
Z[-20+#511]
X[8+#510]
Z[15+#511]
G0B0      ; Coolant off
G0 X[10+#510]
Z[20+#511]
             ; next tool
G0 Z[20+#521]
X[20+#520]
Z[-5+#521]
G0B1      ; Coolant on
G1 X[9+#520] F500
Z[-20+#521]
X[8+#520]
Z[15+#521]
G0B0      ; Coolant off
G0 X[10+#520]
Z[20+#521]
M30

ah, ok did some testing and foud the delay you talking about. 0.166 sec. per M8/M9 in my case
you can reduce the delay about 33% creating e.g M800 and M900  to turn coolant on/off
or about 85 % by using a brain.
