Can't get raster to fire laser

[sliptonic]

I've adapted your config to my laser and have been using it for vector cutting and engraving for a long time (using both magic Z and M62/M63) but have never been able to get raster engraving to work. I recently upgraded my machine and decided to try again.

Config is debian/jessie rt_prempt with Machinekit.

Installing the laserraster.comp only throws minor warnings:
brad@clyde:~/machinekit/configs/2x_laser$ sudo comp --install laserraster.comp

laserraster.comp:270:28: warning: incompatible implicit declaration of built-in function ‘ceil’
Linking laserraster.so
cp laserraster.so /usr/lib/linuxcnc/rt-preempt/

I load the Mona_Lisa.ngc example file (unchanged except I set laser power to 80%). It loads without error and when I run it, the gantry sweeps as expected but the laser never fires.

I uncommented the DEBUG lines in laserraster.comp before installing but I see no error output in /var/log/debug.

Is there anything else I can look at to find a clue?

These should be some amount of dmesg output just when the module loads. If
that isn't showing up running Mona Lisa gocde is unlikely to do anything.
And the issue is not loading the module or it failing to load. I have not
rastered anything or upgraded linuxcnc in years. The laser is currently in
a bunch of boxes being shipped.

If the module is loading then I would guess it isn't getting any input from
the analog pins set by M6?. There should be dmesg output just from all the
line start and raster data loading.

Sorry to hear you've gotten away from it. It seems like development around DIY lasers has kind of stagnated lately. Anyway if you want to ignore this, I'll understand. I'll leave this hear and try to update the issue if I find my problem. Thanks.!

I got it to spit out debugging info now:
Here's the bit where linuxcnc starts up and starts running the sample gcode. It continues like that.

Something is weird with the index and bits being set on the I put raster
data. Those should be setting lots of bits and not just 2 bits per float.
Could be a problem with my metric machine and imperial gcode conversions.
Might be worth a try regenerating the raster file in metric (can't remember
if my generator suppts that).

I have not given up, just moving right now.
