Problem with skipped M62 Code

M62 won't be skipped, (or, at least, shouldn't be) but it does not take effect until a following G-code move.

So:

G0 ....
M62 ....

Will not show any effect of the M62. But

G0 ...
M62...
G0...

Will.

As the docs say "The actual change of the specified outputs will happen at the beginning of the next motion command. If there is no subsequent motion command, the queued output changes won’t happen. It’s best to always program a motion G code (G0, G1, etc) right after the M62/63."

Is this possibly what you are seeing?

What do you expect to happen? You seem to have a lot of

Lines. All of which will turn on an output which is already on.

So, how do you know that it is not having any effect?

Actually, I would expect an error to be returned, as Q isn't valid for M62. I just checked on a test VM here and "M62 P0 Q10" is not accepted.

Have you remapped M62? Otherwise, that simply isn't what M62 does.

I would look at your modifications, then. I have no reason to believe that the base M62 has a problem, and your G-code as-is would simply do nothing as it turns on an output which is already on.
