The TINYG post processor has the spindle speed format backwards!

[ncdubiel]

Hello I just noticed this but after the update when ever I post process tool paths using the tinyg post the spindle speed looks like S12000 M3 When it should look like M3 S12000. Right now it bit me twice the first time I didn't check and it ran the tool into the part with out the spindle on and the second time I set the speed using a line of gcode and this code was so polite it turned off the spindle for me. Could you tell me how to modify the post so that I don't have to go in and manually edit these lines every time I change spindle speed?

Please change this code:

    if (properties.useActiveSpindle) {
      writeBlock(
        sOutput.format(tool.spindleRPM), mFormat.format(tool.clockwise ? 3 : 4)
      );
    } else {
     ...
    }

to this:

    if (properties.useActiveSpindle) {
      writeBlock(
        mFormat.format(tool.clockwise ? 3 : 4), sOutput.format(tool.spindleRPM)
      );
    } else {
     ...
    }

We will also update the generic post.

Thanks for your feedback!

I also had to make this change to the linuxcnc(emc2) post just an fyi for those who have this problem. AchimN's fix is the exact same as for this problem as well.
