Global Variables Desire
-
Hi,
It would save me a good deal of time and a bit of frustration, when creating a new set of configuration files, if there was a way to erase all global variables as part of doing a board reset or code re-start.
Unless there is a way I have not heard about, right now I have to reset the main board which then means I have to re-home the printer and do whatever else needed to restore the state of the printer.
It's not a big issue to be sure but I would like to have it just the same.
Thanks.

i manually swap tool heads so have to make a few changes , i use macros to redefine all the changes , i used the cnc kitchen method,

Interesting system - I am going to check it out.
As to global variables:
I have one file called create_globals.g.
It contains some 80 values, most of what is unique to any given printer.
What that means is I can reuse many commonly needed files not by editing the a multiplicity of files but by editing the values in create_globals.g.
During development of a new configuration these values may change frequently and the file needs to be executed again which currently I can only do by resetting the board.
Yes I could include code like some folks which uses exist and either creates or sets the variable. Not elegant.
So a command to delete all existing global variables would be a boon for me. Not a necessity but just something nice to have.
Thanks for the feedback - I'm looking forward to giving the mutant system a trial.

@fcwilt i didnt intend to promote the mutant system
just the way Stephan used the macros to change the settings .. -

No matter - the system looked interesting.
I was just thinking about such a system a couple of days back as I was replacing the tools in my E3D Tool Changer dealing with all new cabling.
As to the guys system - I didn't understand why he was creating a new file rather than selecting from a set of existing ones. But many ways to skin cat.
Thanks.

@fcwilt i have different tool heads on my printer so i need to reconfigure the printer , it takes me about 2 minutes to swap the head, and then i run a macro for that tool head that loads all the parameter's in to tool.g file so i only have to run the macro when i change the tool head ,

Understood.
Does the code that gets written to tool.g for any given tool head change frequently?
I was thinking settings for any given tool head didn't change often and you only need to select from a set of settings, the settings for the specific tool head being mounted.
Yes? No?
Thanks.

@fcwilt
im not sure i understand your question, but the settings have to change when i change the tool head eg. steps/mm, z offset , max temperature, pressure
advance etc etc -

You could have a single file that uses conditional code to access different sections of code, one section for each tool head. Then all you need is a global variable with a suitable value to indicate which tool head is mounted. That value then determines which section of code needs to be executed.
Not a big deal out all, just thinking out loud.

@fcwilt originally i was going to put an address on each tool head so that the printer would auto configure , but i didnt have enough inputs free on my control board , so ended up doing the macro route , its still something im going to look at using an analogue input 0v=tool 1, 1v = tool 2 etc this way i only use 1 input .
then you could did the setup via global variable's or macros , i like the macro route as all the settings for the too head are in one place .
