[Grbl_Esp32 Issue#681] Macro Button Proposal – Request For Comments

#1 – MitchBradley 于 2020-11-24

We have the existing commands $LocalFS/Run=filename and $SD/Run=filename . Maybe the value of the Macro setting is just a verbatim command.

$User/Macro0=G20
$User/Macro1=$SD/Run=foo.nc
$User/Macro2=$LocalFS/Run=bar.nc

For verbatim GCode, we could use & as a line separator, translating that into a newline before handing it off. I’m unaware of any existing use of & in GCode – although I haven’t done an exhaustive search. Or we could modify the gcode parser to recognize & as an alternative to newline. The former – translate & – would be safer in the event that some GCode programs contain & characters – although I don’t see how those would work at present, unless they are inside comments. If we mod the parser, we could ignore & inside comments.

I like that. A simple replace before doing anything else is probably easiest.

I would prefer a “command file” to execute like Command0.txt .. Command4.txt.
The content of the file could be a line of gcode, the name of a file to execute, etc. Editing a text file is within the capabilities of most users. In time, the format/language can be extended for future needs.

@HuubBuis That is one of the options @MitchBradley is talking about. foo.nc and bar.nc are both command files. One is stored on the ESP32 and one is on the SD card.

I tweaked the code and these 4 macros work fine.

“
$User/Macro3=$LocalFS/Run=upg30.nc
$User/Macro2=$SD/Run=upg30.nc
$User/Macro1=G53G0Z-1&G28
$User/Macro0=G28
“

I have come up with another useful (I think) option, a “macro” to send a (push) message to the GUI, so the GUI can response to buttons.

Is it possible to run a function like this and run it from within the GCode and also with a Macro button?

void sequencerelays(){
digitalWrite(E1, HIGH);
delay(500);
digitalWrite(E2, HIGH);
delay(200);
digitalWrite(E2, LOW);
delay(200);
digitalWrite(E1, LOW);
delay(500);
}

Yes,

Via GCode You can already do this. You would setup (2) digital I/O pins and control them with the following gcode.

“
M62P0
G4P0.5
M62P1
G4P0.5
M63P0
G4P0.5
M63P1
G4P0.5
`

Via Button Macro Setup those same pins and create the macro below, which is the same as the gcode with the & character used as the line end.
`
$User/Macro0=M62P0&G4P0.5&M62P1&G4P0.5&M63P0&G4P0.5&M63P1&G4P0.5
“

Actually, I can think of longer sequences like this which are used multiple (20-30) times within one gcode.
With a way to define and call an arduino functions from gcode, could add a lot of functionality including waiting for input states and any sensor based if/else sequence.

I had to remove all the other files in the Custom directory because it kept saying it couldn’t find etc/settings.h in coreXY.cpp. Only my own costum file in this directory and i control my vacuumcleaner (great)
