Mach3 macro homing
« on: June 10, 2021, 09:40:45 AM »
Hi,

I have a lathe with a C-axis that is engaged with an electrical clutch to the spindle that works very well, I have a macro that enables the clutch and it works fine, then I have an other macro that also homes the C-axis that also works fine, the use of this is when I do more operations that have normal turning in between c-axis operations and these operations needs to be angled to each other. Every time a program calls my macro with homing and it's done I have to press cycle start to continue? guess it has something to do with the homing. My macros are like this:

with auto homing:

While IsMoving()
Wend
DoSpinStop()
While GetOEMled(1000)
Wend
If getoemled(164) Or getoemled(165) Then

Else

ActivateSignal(OUTPUT4)
Sleep(300)
   If GetOEMLED(845)   Then
      Code "G91 G0 C35"
      While isMoving()
      Wend
   End If
Code "G90"
DoOEMButton(1027)
While ismoving()
Wend
End If



without homing:

While IsMoving()
Wend
DoSpinStop()
While GetOEMled(1000)
Wend
If getoemled(164) Or getoemled(165) Then

Else

ActivateSignal(OUTPUT4)
Sleep(300)
End If   



Hope you can help me out, or give me a clue what to look for.

Regards Morten.

Thanks for the suggestion, I tried changing my macro, but if I run a g-code where it calls that macro it does not home my c-axis, and if I put it in the MDI it homes the c-axis but after that it kind of hangs for like 20 sec. before mach will accept a new command.

Yeah it's strange, I use Mach3 version R3.043.062 - the recommended version with my ethernet smoothstepper.

sorry, missed your answer.

for the Moment the only idea i have is, that Mach may be corrupted.
i would try to install a fresh copy.

Have you tried using the Standard button call DoButton (27)

or

Code ("G91 G28 C0")
While IsMoving()
  Sleep(25)
Wend

Hi,

Thanks for your reply, tried both solutions, the dobutton(27) also waits for cycle start to be pressed if called from a gcode, the other one works if I run it in the editor, but if called from a gcode it just does not home the axis, but does not wait for cycle start.
