Is there any advantage to using m19 instead of using M62 - M66 as in the rest of the tool changer sequence?


Only a very small one, in that it saves a DIO pin, and the G-code is slightly simpler and clearer.

My solution to the problem. M19 and then check if the spindle is uninterrupted (P6).

Then an M5 at the end of the tool sequence. To stop the orientation.

M19 R0
(MSG, Orient spindel 01)
M66 P6 L3 Q5; Check if spindel is Oriented?
o101 if [#5399 EQ -1]
(abort, Fail orient spindel! 01)
o101 endif 

(rest of toolchanges sequence)

M5

M2

Why do you persist in using rising-edge with timeout rather than simply checking the state of the input?

For the spindle to have time to index before alarm.
Was the idea.

Receives the following error message when I load a g code with the tool changes.


I comment off the line N25 the file opens properly. The text of the error message is from my tool changer sequence.

What causes this?

Execution of the M19 won't complete until the spindle-is-oriented pin goes high.
