Hi

I am starting to learn Ucamcopy but in the interim I am just using regular polygonal shapes.
Is there a way to record a series of points from either the digitise or probe screens while using the webcam?
Planet CNC has this function built in but I don't want to licence another package.

In practice:
Open the camera window
Jog to the first point
Click "record"
Jog to the next point
Click "record"
Rinse and repeat then export point list to a DXF file

Thanks in advance for suggestions.

Never heard of this feature but I am interested and following.

@wmgeorge

I had some software that worked (sort of) with Mach3 years ago but cannot for the life of me find it now.

I am just getting to grips with UCCNC and was thinking maybe this could be done with a macro that uses a loop of message boxes to collect the data points by reading the DRO values and writing them to an array then outputing that array to a CSV file for import as a point list into CamBam. Does anyone know if the macro feature have the ability to write to an array?

Through the power of ChatGPT I got the following code, that AI freaks me out, I would not want to be a coder when it really gets smart.

I asked it:
I want a C# macro that uses a message box to capture a series of input values then write those values to a CSV file
Can you help me


The reply was:
Sure! Here's an example of a C# macro that prompts the user to enter a series of values using message boxes and then writes those values to a CSV file:

I attached this to a button as Macro 20000 but unfortunately UCCNC gives me the very unhelpful result of:
Script error: M20000 has error(s) and cannot be executed.

Anyone have any ideas ?

Yes, I do realise I am spamming myself

Updated code but still won't run. Any suggestions most gratefully received.

SOLVED !!!

1. Never ever use C# when you can use VB
2. Found this little gem in the Macro detailed instruction file
If the first line of the macro code contains the #VB directive then the software uses the VisualBasic compiler to compile the macro instead of the C# compiler.
3. Don't overthink things, why prompt the user to enter co-ordinates when the machine knows exactly what they are?

And the result is this working code. Hope someone finds it useful, I just stuck it on a button and press that every time I want to record a point.

Code: Select all

#VB
Dim Xpos As Double = exec.GetXmachpos() ' Get the current machine coordinates
Dim Ypos As Double = exec.GetYmachpos() ' Get the current machine coordinates
Dim filePath As String = "C:\UCCNC\DXF.txt" 'Change this as suits your System
Dim file As System.IO.StreamWriter

MessageBox.Show(Xpos & " " & Ypos,"Point added to file")

file = My.Computer.FileSystem.OpenTextFileWriter(filePath, True)
file.WriteLine(Xpos & "," & Ypos &",0") 'Appended a trailing zero so CamBam will accept this as a valid point list file
file.Close()
