//==============================================================================
// creates error codes
//==============================================================================
const rawText = `
1	Expected G-code word	Grbl expected a valid command (like G1, M3, etc.) but didn't find one. This is often due to a blank or malformed line.
2	Bad number format	A number in the command was invalid or improperly formatted.
3	Invalid statement	The line contains an unknown or unsupported command.
4	Negative value	A negative value was used where it isn't allowed, such as a feed rate or spindle speed.
5	Homing not enabled	A homing cycle ($H) was requested but homing is not enabled in the settings.
6	Minimum step pulse time violated	A step pulse was issued faster than the configured minimum time ($0).
7	EEPROM read fail	Grbl could not read its settings from EEPROM. May indicate hardware issues.
8	Not idle	A command was issued that requires the machine to be idle, but motion or another operation is in progress.
9	G-code lockout	A G-code command was blocked due to machine state. Common after a reset or alarm.
10	 Homing not set	The machine requires homing to establish its position before executing the command.
11	 Line overflow	A G-code line was too long for Grbl’s internal buffer. Shorten your lines.
12 	Step rate too high	Grbl could not generate step pulses fast enough for the commanded movement.
13	 Safety door open	A command was blocked because the safety door is open.
14	 Build info overflow	The build info string exceeded the allowed character limit.
15	 Setting disabled	A command depends on a setting (like homing or soft limits) that is disabled.
16 	Negative value in settings	A setting value was set to a negative number, which is invalid.
17 Invalid jog command	A jog command is improperly formatted or unsupported.
20 Unsupported command	The command is not supported by Grbl’s G-code parser.
21	 Modal group violation	Two conflicting commands from the same modal group (e.g. two motion modes) were used together.
22	 Undefined feed rate	A motion command was issued without a feed rate being set.
23	 Axis command conflict	Two axis words used inappropriately together, such as in arcs or jogs.
24	 Invalid target	The target position is invalid — for example, in an arc that can’t be generated.
25	 Invalid arc radius	Arc command contains a radius value that doesn't make geometric sense.
26	 Invalid G-code word	A word was used in the wrong context or is not allowed for the active command.
27 Invalid line number	A line number was used incorrectly or exceeds limits.
28 Value word repeated	A G-code word was used more than once on the same line.
29	 G59.x WCS error	A G59.1, G59.2, or G59.3 work coordinate system was used but isn’t supported.
30	 G53 with offset	G53 motion cannot be used with G54–G59 offsets.
31	 Invalid real value	A floating-point value is invalid (e.g. NaN, too many decimal places, etc.).
32	 Arc axis missing	An arc command is missing a required axis word.
33	 Arc format error	Arc command has incorrect or conflicting data (e.g., missing radius and offset).
34 	No axis word in motion	A motion command was issued without specifying any axis to move.
35	 G2/G3 not allowed	Arc motions (G2/G3) are not allowed in certain states, like jogging.
36 Unused words	Extra G-code words were found that don’t apply to the current command.
