How To - Pausing a print at a specific layer. (Simplify3D)

[brandonr49]

After reading through some of the Marlin documentation this appears to be impossible to do without an LCD screen. Without it the M0 command just runs straight through.
Is that right? I have to spend $100 on a hardware upgrade for something that could be supported in software?
Why doesn't Marlin support the M226 command?

If you are referring to pausing a print, yes you can do that without an LCD screen. (I do it for color changes all the time....no LCD.)

Go back and read the first post in the thread - the M0 command is ONLY used on LCD screens, the others use a different code.

The pause gcode depends on the host software you are using. If you are using S3D or OctoPrint, M0 is correct. If you are using Pronterface or Repetier Host, it is @pause. viewtopic.php?f=3&t=1584

Ok... this same came up in another thread recently but I'm posting it here instead so others don't run into the same problem trying to follow this thread....

I just tried a pause/color change tonight and they must have changed something in S3D in the last revision or so because I too am now getting a retract upon unpausing the print.

Maybe they changed something with how the G92 command is handled or something but my pause code is no longer working with S3D.

It still works fine running with Octoprint (assuming you use the M0 over the M25 command.) but if your using Simplfy3d you might be SOL until someone smart enough figures this out again.

Oh groovy.

Will have to try this method...

I've always used the 'Stop/Start printing at height' settings in the advanced tab of Simplify3D. What I didn't like about this method :

1. This completely stops the print, does not just pause it. So must manually restart at a certain height
and remove the gcode starting script on the 2nd run so nozzle does not hit the print.
2. The settings are in mm rather than layer height! Would like to have both. Using a ruler to measure mm is not precise enough.

So yeah this method seems better, except that you have to edit the gcode manually...

Pronterface doesn't recognize @pause
