Variables reading and writing
« on: May 17, 2014, 12:05:25 PM »
Been mucking around looking in to reading and writing to variables and trying to figure out the variable#'s
Reality, I was trying to find a way to set the persistent dro's so when I restart it has the same dro coords as when it shut down.
not sure where it picked these from but can not seem to reset them, as the data is held in the xml file not the machine.ini

There has to be a way to write them to memory on shutdown or maybe write them to a file and then read the file and fill the variables with the stored locations.

-- inst 0 is the hobby version 0 is the only one, the pro versions will have more capabilities and Mach4 can then run multiplies instances.
-- this was placed under a button click to read and set, step thru and experiment.
inst= 0

--how to read variables
local valx = mc.mcCntlGetPoundVar(inst, 5021);
local valy = mc.mcCntlGetPoundVar(inst, 5022);
local valz = mc.mcCntlGetPoundVar(inst, 5023);
local vala = mc.mcCntlGetPoundVar(inst, 5024);

--how to set variables (in this case to zero)
mc.mcCntlSetPoundVar(inst, 5021, 0);
mc.mcCntlSetPoundVar(inst, 5022, 0);
mc.mcCntlSetPoundVar(inst, 5023, 0);
mc.mcCntlSetPoundVar(inst, 5024, 0);


-- this is a listing of a lot of the variables I found. As you can see there is a pattern to some like kinds
not all as most of course are zero's and there are a lot of them. Your numbers will vary for most.
I labeled some I could get a handle on. Others will have to wait for Documentation.
Writing a while loop to read all the variables > 0 and then writing to a text file or even a wizard is in the plans.

HIYA Craig, I have a #VAR report generator for MACH3 that does that trick. It sweeps through ALL the Var Numbers and reports ONLY the one that are > OR <  0

IT IS important that you check for values < AND > because some values are negative values.

Save the text file and send it to Notepad for viewing and printing.

I trick I use a lot when trying to find something in the VARs . I input a Value into a DRO that is easy to spot then I create the report and open in Notepad. THen do a search on that string to find the value and I then HAVE the Var number where I found the value.


Thnaks, (;-) TP

ALSO Steve Wrote a #VAR monitor for Mach4 that you can set a range and View the Values .

It works great but does not give the option to save or print. You CAN lock it on top if needed, that works well for testing code as the values are updated in real time.

have not see anything other than what Mach4 provides
TP I too wrote a plugin years ago for that very same purpose.

also I use the iReg0 register (instance) I can read and write to it from other external scripts, such as a Wizzard that can read the Axis DRO's or pass and set feed rates

Menu Diagnostic then Reg File list of all the #variables is at the bottom

TP I do believe I was referring to that same ability you mentioned (Mach4 provides) unless it is a separate program you received.

You just type faster than I do (;-) it is the same thing. One nice thing is it runs in real time AND yo can lock it on top and view the values as they change when running a Gcode Parametric program. SAME as the Var monitor in Mach3.

NOW IF you can figure out HOW to see the #var values in the Gcode window AS it runs THAT would  be a NICE touch (;-)

  FOR EXAMPLE

G01 X#1 Y#2 Z#3    (#1=10.203 #2= 1.0435 #3= -1.128)

OR have it pop up in a small side window off to the side of the Gcode window.

BUT it would need to stay in sync with the Gcode LINE.

maybe you can associate them with the line number when read and then display as used

guess it depends on if the look ahead read line has a line number and was given a variable that can be used.

Would be interesting to view the variables while running gcode variables,  guess I could try that  ::)

TP you sure do come up with all kinds of things others should do  >:D Trouble Maker

current machine goto points

variables 5001 current goto point in x
variables 5002 current goto point in y
variables 5003 current goto point in z
variables 5004 current goto point in a
or
variables 5021 current goto point in x
variables 5022 current goto point in y
variables 5023 current goto point in z
variables 5024 current goto point in a
