single line gcode blocks with multiple commands?

[Mike Estee]

tinyg can't process the following line:
n100g0x100y100z10s1300m03

i've noticed there are a lot of generators that will produce blocks with multiple g/s/m codes on the same line. what's the official word on tinyG's parser?

Can you tell me what part is not working? I'm not at a bench to test, but I have been tracing the code with that line of Gcode and all things seem to be happening in the correct order of operations:

- The S word is set

- The M3 is enacted

- The move is performed.

Is is possible that you encountered this line when the planner buffer was full? This line queues 3 events (listed above) but it's possible that the planner queue was overrun.

Sometimes I see spindle start failures running the following:

T1M6

G17

G0Z10.000

G0X0.000Y0.000S1300M3

G0X20.318Y13.946Z1.000

G1Z-1.600F50.0

G0Z1.000

G0Y16.420

G1Z-1.600F50.0

..

..

..

Let me verify it isn't some other problem before I send you on a wild goose chase.

Here's a simple test. Make the following change in controller.c

static uint8_t _sync_to_planner()

{

// if (mp_get_planner_buffers_available() == 0) { 

if (mp_get_planner_buffers_available() < 3) { 

return (TG_EAGAIN);

}

return (TG_OK);
