Can I insert a Pause at certain layers ?

Can I insert a PAUSE in the Gcode at certain levels?

For instance, by making the pause conditional in the 'after layer' section ?

(f.i. "if layer equals 23: PAUSE" )


or by other means, not editing the gcode after slicing....

Doing math with parameters and using if-then statements are currently not supported.

So, this could become a feature request .. maybe ?

Unless you are wanting to pause a very large number of times, what's the problem with editing the G-code file? You just load it into a text editor, search for the Z height you want to insert the pause (e.g. search for "Z2.5" if you want to pause at a height of 2.5mm), and put in the appropriate pause command then save. All done in literally seconds. I do this often when I want to change the colour at a certain layer - e.g. to print raised or embossed text.

Yes,

that is the alternative,
but last time I tried, the pause was called and resume was immediately called too..So I did miss the moment.


So what went wrong ? I will try again.

Sounds like you may be using the wrong command to pause. The command to use depends on your controller & firmware - what printer is it for and what command are you used to pause it? Maybe write a simple bit of G-code to move the head about without extruding and try various pause command methods.

I am running Repetier firmware on repetier host.

Can't find a repetier supported pause command in the reprapwiki on Gcode

I believe the note not to use M25 in a gcode file is for RepRapFirmware and that's actually the correct command for a Repetier machine. It might work better with an M400 before and after it (which waits for current moves to finish and clears the read-ahead buffer).

If you're not running the print off the SD card (though I generally recommend doing so), you can handle a pause through Repetier-Host by inserting @pause.

This is apparently a feature to which they've been doing some changes in the more-recent versions of Repetier firmware.

Yesterday I ran a modified Gcode with M226 at the required level.

It never paused. It just ran all the way to the end.
I posted a question in the Repetier forum, maybe there is the solution, as it is a repetier issue in my case :-)

I am not running from SD, but from the repetier host on Windows10

So you mean I can put the string @pause in the Gcode ?

As has been said, use the command M25 for Repetier. I advise you to run from SD card, which will prevent jerky movements if the communication is delayed due to Windows getting temporarily hung up with background tasks etc.

I have been testing with the @Pause command.

This is exactly what I needed. I home the X before so no droop on the object. Thanks.

Now.... it would be nice to know when that moment has arrived.
So my thoughts are to sound an external alarm when @Pause is triggered.

Any way to achieve someting like that ? Shorting a switch somewhere so that switch can power my alarm that is far away by wire ?
