M204 used instead of M201 when setting acceleration

[nebbian]

Version

1.31.6-prusa3d

Operating system type + version

Mac OS X El Capitan 10.11.6

Behavior

Setting the acceleration in the advanced tab sends M204 GCodes instead of M201.

To reproduce, set the acceleration in the advanced tab to 100 for the first layer, then 1000 for the default acceleration.

The GCode produced uses M204 to set acceleration, instead of the more compatible M201. Note, Repetier uses M204 to set PID values, not acceleration.

Here are some links describing the problem:
repetier/Repetier-Firmware#290
http://reprap.org/wiki/G-code#M201:_Set_max_printing_acceleration

Is there a way to modify the printer settings so that it uses M201 instead of M204?

This isn't really a new request, more a bug fix.

Not that it really helps, but I've added the config file here:
acceleration_config.ini.zip

Thanks, I know @lordofhyphens did some fixes for repetier on the main Slic3r. I will port them once I have the current code base released.

Thanks @bubnikv for the quick response 👍

For anyone wanting a quick fix without needing another build of Slic3r, I've created this post processing script that seems to do the job:

#!/usr/bin/perl -i
#
# Post-processing script for changing default M204 acceleration control,
# to M201 which is compatible with Repetier firmware

use strict;
use warnings;

while (<>) {
    if (/^(M204\s+S(\d+))/) {
        printf "M201 X%d Y%d Z%d E2000\n", $2, $2, $2;
    } else {
        print;
    }
}

Hopefully fixed by #106
Thanks to @lordofhyphens
