Hi Guys,
my MPCNC is up and running now.
Time for some add-ons
I have a 2W laser laying about… so I made a mount for it.
Hooked up the 5V TTL connection to pin 44 and GND… But laser does not turn on.
As I usually mill from SD card, I’m trying repetier host to turn on / off the laser using the M3 / M5 command.
But the state of pin 44 does not change…
What am I doing wrong?
Thx
Tom
Try to check
M3 o200
M42 p44 s200
I don’t know what board you are using, but…
IF it is RAMPS1.4 and you have remapped the D9 fan output to pin 44 (this is the way I use it)…
use M106 Sxxx to turn the laser ON at intensity xxx, and
use M107 (or M106 S0) to turn laser OFF

After an entire sunday or reading, google searches and reading through the marlin code, I found that, in my case, the M3 and M5 commands controle pin D6 on my ramps 1.4 board.
So I have finally got the laser to fire!!
Thanks for the replies guys
Once I’ve got the laser fitted to the MPCNC, I’ll post a picture.
