Hello Damir,

the feedrate thing is not working to seperate between
G0 and G1. if i look to your g-code maybe we can use the
z-axis as second trigger like this:

act_Z=GetDro(2)

If (act_Z>69) and (GetLed(4)=True) Then
  If Not IsActive(Input1) Then
    DoSpinCW()
  End if  
End If

  If IsActive(Input1) Then
    DoSpinStop()
  End if

My Z-axis is never constant so that every time I need to change the script.

Hello Damir,

if the function should only be enabled between M3 and M5 call in
g-code we can use them to enable like this:

add this conde in M3
Code: [Select]
setUserLed(2100,1)
add this conde in M5
Code: [Select]
setUserLed(2100,0)

and this in macropump
Code: [Select]
If (GetUserLed(2100)=True) and (GetLed(4)=True) Then
  If Not IsActive(Input1) Then
    DoSpinCW()
  End if 
End If

  If IsActive(Input1) Then
    DoSpinStop()
  End if 

the only thing i see, that nothing resets the UserLed if
you cancle a program.
but give it a try.

Unfortunately again nothing
Start spindle motor and turn it off when it detects input, after that it does not start spindle motor.

Hello Damir,

tested here:

M3
setUserLed(2100,1)

M5
setUserLed(2100,0)

macropump
If GetOEMLed(2100) and GetLed(4) Then
  If IsActive(Input1) Then
    DoSpinStop()
  else
    DoSpinCW()
  End if  
End If


don't ask me why GetUserLed does not work, GetOEMLed is working.

ok i am pretty sure the next problem will be the dwell of the spindle,
because it is locking axis movement and so Input1 will go off again.

so i think the only practicable way well be to drive a axis not tangential and
control it miz g-code, something like this:

G0 Z0 A0
G0 X100 Y100
G0 Z70
M3
G1 X0
M5
G1 A90
M3
G1 Y80
M5
G1 A180
M3
G1 X100
M5
G1 A90
 

and so on.
what means you can only do straight line an no circles
(witch would not work anyway with this code for turn on/off spindle)

OK there are 2 servos one drives the tufting head ( C axis )  and the other(Z axis) does what ?  Why don't you simply program the stops and starts in the Gcode program ??
