Hey Team,my problem is that M62 skipped after G0 or G1.  I play .ngc File with G and M code in it. M62 Code is expanded with a Timerparameter Q => That will open the Output and close after X*100us (Timer).Now i interested in how interpret linuxcnc that M-Code after G0 or G1 is set and it is possible to use M-Code one after another as quickly as possible?

in the attachment you see the ngc-File:

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?

Thx for this Answer. I check the programm again but in line 1160/1161 the next M62 command have a G1 before and G0 after so that i think that the M62 Command wouldn't be skipped after move to G0. But it will.

What do you expect to happen? You seem to have a lot of
M62 P0 Q10

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.

additional question: at what interval may the M62 orders follow?

i just modified to Q Parameter. in my case M62 P0 Q10 would open Output and Close Output after timeout.

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.

If there are no copyright or legal problems, I would give you the folders with the changes in the EMC.
