Hi all

I already posted in the prusa section but I will probably get answers with developers.

I have modified my prusa i3 with a laser.
The laser uses M106 and M107 commands for on and off.
But when I select stop from the lcd menu, the laser stays on. How can I add in Malin the M107 command to be sent while I select stop?

In the same idea I would like to add an external emergency stop button I would connect to an available pin on the ramps. I want the button to send the stop command also. Has anyone already done something like this ?
