Simple g-code streaming script for grbl
|
|
|
|
Provided as an illustration of the basic communication interface
|
|
for grbl. When grbl has finished parsing the g-code block, it will
|
|
return an 'ok' or 'error' response. When the planner buffer is full,
|
|
grbl will not send a response until the planner buffer clears space.
|
|
|
|
G02/03 arcs are special exceptions, where they inject short line
|
|
segments directly into the planner. So there may not be a response
|
|
from grbl for the duration of the arc.
