=== Resetting LinuxCNC state ===
* The previous job might've left LinuxCNC in a non-standard state, reset it by using the following commands in the MDI tab:
M2    (end program, reset most states)
M65 P0 (beam off)
M52 P0 (disable adaptive feed)
S1    (reset power factor to 100%)
* Set Feed and Spindle override sliders to 100%


=== Beam does not turn on/stays on all the time during Graster job ===

* Ensure the coordinate system is reset by going to '''Machine -> Zero Coordinate System -> P1'''. You can't use the "touch off" feature of AXIS with Graster.
* Make sure there are no stray Graster Streamer windows open, multiple windows will fight for the graster buffer and output garbage
* (Note: This applies to the old graster, not graster2) Ensure the coordinate system is reset by going to '''Machine -> Zero Coordinate System -> P1'''. You can't use the "touch off" feature of AXIS with Graster.

* Check to ensure the beam override switch is not on.
* Check to ensure the beam override switch is set to Armed.
* Check to ensure that a non-zero power level has been selected.

* Switch Axis to show "Machine Coordinate View" and make sure the Z axis is touched off at the machine's zero point.  if Z is touched off high or low, the laser control could be erratic.

* Check to make sure the red light outside the laser room is on and spinning. If it is not, speak to someone who has previous laser experience.
* Check to make sure the green Laser light on the control box is on. If it is not, speak to someone who has previous laser experience.


=== Aborting a test/job ===
=== Aborting a test/job ===
* If streaming a graster job, the easiest way to abort the job, without having to kill processes manually, is to hit the big ESTOP switch

=== Ventilation system makes a soft buzzing and the lights dim when turned on, air is not moved ===
* This happened on March 28, 2010, and again in early 2013.
* '''Ensure the motor is unplugged before performing any further troubleshooting!'''
* Untape the side of the ventilation motor 'can' closest to the wall, and bend the metal back some so you can see the pulley on the motor and the belt that drives the blower.
* Spin the blower by hand (push/pull the belt along).  If it does not spin freely, investigate why.
* Ensure nothing (metal, loose tape) is interfering with the belt, ensure nobody has anything that will get caught in the belt/blower/motor, and plug in the ventilation system.  This manual manipulation resolved the issue the previous time it happened.
* If this resolved the issue, put the ventilation system back together, taping up any openings that might let air in/out in the wrong place.
* If this did not resolve the issue, troubleshoot further.
* Mail the members list to let everyone know it happened again, so we can troubleshoot what might be happening and try to resolve it.
