DDCSV system supports macros. Macros support loops, conditional control languages, and common maths function calls.

For user processing files whose size is less than 100K or whose initial character name is sys, the system automatically scans the program structure before processing or emulation so as to implement the loop and branch statement support.

Note: The main program number of macro processing program defaults to 0.

Example:
Processing file: sysuser1.nc
O0000 (main entrance)
...
M98P0001L3 (call subroutine No.1 three times)
...
M30

O0001
...
M99

DDCSV macro variable Description:

#0- #49 for each subroutine internal private variables;
#50- #499 is the system internal variable area 1;
#500- #999 is the system parameter area;
#1000- #1999 is the system internal variable area 2;

The chs or eng file defines the system parameters that the user needs to configure, for example:

#1 -t2 -s1 "language setting" -m16 -min = 0.000 -max = 1.000 -i0 "Eng" -i1 "Chinese"

#n n is the parameter number (0-499), n + 500 is the macro variable number of this parameter;
-t is used to specify the type of parameter, t0 is an integer, t1 is a real number, and t2 is a selection type.
-s1 defines the name of the parameter;
-s2 defines the parameter unit;
-m parameter group, m0 that the parameters in the parameter configuration page does not show;
-min minimum parameter
-max maximum parameter
-i The text of the relevant entry is configured through it when the parameter type is selection type;

Few of us have rar. Please use .zip format

Hi!
Sorry, I will use .zip format later

Hi JPoepsel!
102 subprogram is used to play back the track of the tool. Before using the 102 subroutine, the track must be recorded, the attachment is an example related to it.

DDCSV Coordinate System Description:

The coordinate systems in DDCSV system include machine coordinate system, G53 coordinate system and G54-G59 coordinate system.

The machine coordinate system is established by home operation or zero under MACH. Read # 864- # 867 (X, Y, Z, A) to find the position of the tool in the machine coordinate system.

G53 is based on the machine coordinate system. # 800- # 803 (X, Y, Z, A) describes the distance from the origin of the G53 coordinate system to the origin of the machine coordinate system. Adjusting these parameters can reconstruct the G53 coordinate system. Read # 868- # 871 (X, Y, Z, A) to find the position of the tool in the G53 coordinate system.

The G54-G59 coordinate system is based on the G53 coordinate system. # 804- # 807 (G54 X, Y, Z, A), # 808- # 811 (G55 X, Y, Z, A), # 812- # 815 (G58 X, Y, Z, A), # 816- # 819 (G57 X, Y, Z, A), # 820- # 823 G54 X, Y, Z, A) respectively describe the distance from the origin of G54-G59 coordinate system to the origin of G53 coordinate system, and adjust these parameters to reconstruct the G54-G59

coordinate system; Read #840-#843(G54 X、Y、Z、A)、#844-#847(G55 X、Y、Z、A)、#848-#851(G56 X、Y、Z、A)、#852-#855(G57 X、Y、Z、A)、#856-#859(G58 X、Y、Z、A)、#860-#863(G59 X、Y、Z、A)to find the position of the tool in the G54-G59 coordinate system.

#516 describes the system currently working coordinate system, 0 corresponds to the G53 coordinate system, 1-6 corresponds to the G54-G59 coordinate system, 7 corresponds to the machine coordinate system.

Many thanks for this information. It is very useful.

One question though
I am still using version 1.1

I am trying to write a tool change macro.

Parameter #268 is "H01 tool offset"

If I set this and others to know values I cannot see the value as parameter #768. Its value is 0

Your Englisdh is much better than my Chinese!!

Thanks for the reply (and also the tool change macro example - will try this out later )

My question is:
If I set parameter #82 to 20.00 (Safe Z retract Height) in my controller, I can then use #582 in my script as it will equal 20.00

If I set parameter #268 to 10.00 (H01 tool offset) in my controller, I can see that #768 in my script is set to 0.00

Will

{UPDATE}

My mistake. I forget to send the M3 command!! Now all works

Hi ytiu!
Your answer proofs, that at least I was not completely wrong with the reverse engeneering in madmodder.net (see https://madmodder.net/index.php/topic,11598.875.html) ;-)

One question:

In  macro O102 I found the

RDRECODE[#1]

instruction. Have you any informations what it does?

Second (and last) question: Is there any chance to place text on the display (e.g. as hint for the user for manual tool changes)? I know, that comments in the G-Code are displayed (e.g. the line "M5 (Change to tool 1!)" will display the comment), but the possible text size is somewhat small and there is no way to change this comment in macros e.g. depending on the tool number).
Users of Fusio0n360 and other software using a posts for GCode-generation have the alternative to implement the GCode commands in the post (for Fusin360: using Javascript), but implementing it directly on the device is far better for the "value" of the DDCSV ;-)

All the best and thanx again for your answers!

Josef

Hello ytliu,

Are there any other commands (like RDRECODE, WRRECODE) available? Could you provide some command list?
For example to send data to MPG RS232 port?

Regards
Lukasz
