General Mach Discussion / Read working coordinates in macro

« on: May 23, 2017, 08:49:27 AM »

When using GetOemDro(802) it could be a disaster if the user has pressed the machine coord button as it then read the the machine coordinates instead of the working coordinates.
I could of course check if the button is pressed and abort but is there an other way to read only the working coordinates?

General Mach Discussion / Re: Spindle orientation with Mach3 Need help

« on: February 04, 2016, 01:47:40 PM »

Well there is no PLC there now so I will control the valves and motors either via Mach3 or a PLC.
So the question is how fast can Mach3 process a input in a macro and stop the spindle?
I would say that it has 0.5s or so to react.
And then there is the Smoothstepper in between...

General Mach Discussion / Spindle orientation with Mach3 Need help

« on: February 04, 2016, 11:40:12 AM »

I´m retrofitting an old CNC-machine for wood with a bunch of spindles on a big vertical wheel of which each spindle has a different combination of cams and switches so that it can find the right spindle.
So, I wonder if its possible to do this in Mach3, for the programming its not a problem but can Mach3 time it reliable? (with the Ethernet smoothstepper)
I have tried before to stop a spindle when hitting an inductive switch but it was stopped sometimes directly and sometime it took a second or two from the switch was triggered until Mach3 turned it off so that did not work very well.
Has anyone managed this or do I need a PLC to make it work?
Would Mach4 work better than Mach3 for this?

Thanks.

VB and the development of wizards / Re: How do I write to or change a specific part of a file?

« on: November 05, 2015, 01:53:55 AM »

is this what your wanting?

x1 = getdro(0)
y1 = getdro(1)
z1 = getdro(2)
Print #1, "Here are the X, Y and Z coordinates"
Print #1, "My X = ", x1
Print #1, "My Y = ", y1
Print #1, "My Z = ", z1

Thanks, bur how is this different from my example above?

My thought was that it must be an easy way to just tell it where to go in the file like
Print #1, X; row 10 or something like that but I can only find various to complicated ways to do it (at least for me) so there for I hoped that I missed something and that someone here new an easy way like my example.

VB and the development of wizards / How do I write to or change a specific part of a file?

« on: November 04, 2015, 09:12:33 AM »

How can I control where to write in a file?
For example if I do this:
Dim X As Double
  Open "C:\Mach3\myfile\myFile.txt" For Output As #1
  X = GetDRO(0)
  Y = GetDRO(1)
  Z = GetDRO(2)
  Print #1, X
  Print #1, Y
  Print #1, Z
  Close #1


But then maybe I just want to write the value of the Y axis and have the other ones intact, or if I want to add more and more values after the others, how can I control where in the file the value is written?

G-Code, CAD, and CAM discussions / Re: THC on off problem

« on: August 27, 2015, 01:21:29 AM »

How do you mean? thats exactly what the macros are doing:

M101 macro:

Rem THC On
If GetOEMLED(24) = FALSE Then 'Check if off, then turn it on, else do nothing
   DoOEMButton(123)
End If

M102 Macro:

Rem THC Off
If GetOEMLED(24) = TRUE Then
   DoOEMButton(123)
End If
   
I want do be able to set cutting rules in sheetcam to control the THC, thats why I want this to work.

G-Code, CAD, and CAM discussions / THC on off problem

« on: August 26, 2015, 05:00:26 PM »

I´m having very much problem with turning the THC on in a gcode.
Included are the macros I use for turning the THC on and off and the file which I test the function with.
By them self the macros work fine, and if I delete the M101 in the gcode file it also work fine,
but when I run it as it is now it turns the THC on and then the Torch, and then nothing happens?? until I hit stop and the run again, then it continues, its like there is something wrong with the macro that I have to abort with the stop button.

I have also tried to move the M101 after M3 and then it hangs after M101.
There is no problem with klicking the THC button when the program is running.

I have been trying different approaches now for two hours and are supposed to have this ready for a customer on the morrow (in Sweden that is) so if anyone could help me it would be much appriciated.

M101 macro:

Rem THC On
If GetOEMLED(24) = FALSE Then
   DoOEMButton(123)
End If

M102 Macro:

Rem THC Off
If GetOEMLED(24) = TRUE Then
   DoOEMButton(123)
End If
