Value array

Hi everyone,

first of all I want to say thanks to everybody in this forum that helped me commissioning my system so far.
If anyone needs help with his MESA 7C80 write me. I will support as good as I can.

I'm planing to do a battery cell welding system with Linux CNC.
The first step is done. I'm using the MESA 7C80 which works very good so far. The system is moving. Now it's time for the next step...programming the movement.

I'm coming from PLC programming. What I'm aiming for is something like a main Programm and a seperate file with parameters which are used in the main program. These paramaters are for example: X and Y location for each battery cell, numbers of welding spots for each cell and so on.

The main programm should be able to look up these parameters by an index number.
Is that possible? If it is poosible. What than is the keyword?

Thank you in advance.

  Hi Andy,
thanks for your quick reply.
I would like to use a special torch to weld copper cell connectors onto lithium-ion cells. Any number of spot welds can be set on a cell. These spot welds are located on an imaginary circle that is coaxial with the center of the cell. The parameters for each battery cell in the pack are: - X and Y coordinate of the center of each cell - Circle diameter on which the spot welds are located - Number of spot welds on the cell So I need a file that contains this information for each cell. A loop runs in the main program. The loop counter corresponds to the index to access this information. I hope you now understand a little better what I intend to do.

In the Image you see a cell with three welding spots.
 

I will need something like a multi-dimensional array to store the data for each cell.

1. dim: Cell number
2. dim: X-location of cell centre point
3. dim: Y-location of cell centre point
4. dim: circle diameter on which the welding spots are located
5. dim: number of welding points

I tried to do it with variables within an INI-file

which could look like this:

[1]                      <- battery cell number
X=100               <- X location of battery cell
Y=100               <- Y location of battery cell
DIAMETER=3
PPOINTS=4

Inside my gcode it looks like:

G1 X#<_ini[1]X> Y#<_ini[1]Y> F1000

That works pretty good BUT the  question for 1 million $ is:

How can i make section a variable so i can access the sections by a loop counter?


 

Sounds promising. I will try that. Many thanks Andy.

What dooes MDI mean?
Is there any documentation of how creating a simple GUI to enter paramters?
