M24: Start/Resume SD Print

Issuing an M24 starts printing the file selected with the M23 command.

Resuming Paused Prints

If the print was previously paused with M25, printing is resumed from that point.

When resuming a paused print, Smoothieware automatically runs the macro file resume.g (if it exists) prior to resuming.

Restarting from Beginning

To restart a file from the beginning, use M23 to reset it, then M24 to start printing.

Print: In this context, "print" refers to running a job on any Smoothie-controlled device such as 3D printer, laser engraver/cutter, CNC router, etc.

Format

The command is used as such:

M24

Which means: Print the file that was previously selected by the M23 command.

Parameters

The M24 command requires no parameters.

It operates on the file previously selected with M23.

Example

If your SD card’s contents were:

config.txt
firmware.cur
Readme.txt
myGcode.gco

And you previously executed:

M23 myGcode.gco

Then issuing the command:

M24

Will result in the G-code commands in the file myGcode.gco being executed.

Configuration

The M24 command requires no special configuration settings.

However, you can create a resume.g file on the SD card to run custom G-code when resuming from a pause.
