First forum post here! I hope I did this right and if not my apologies.
Ive been trying to make a value chart with my laser with each grid square being a different power and speed. Being that I can only have up to 30 layers I have to complete the grid in different sections.
I started the next section adjusting the power and speed for each layer but when I start I get the console message; Alarm 2: on or near line 5. My understanding is that Alarm 2 means something is out of bounds that the laser cant reach BUT the laser has no problem framing the work so why would it give me that alarm when I try to start engraving it? I could move it potentially negating the alarm but I donât wanna waste another piece of wood just to start all over again and if this problem happens again I would like to know why and how else I could solve it.
Does it have something to do with line 5? Maybe I changed a setting without knowing I did.
Framing doesnât include overscan moves, so itâs possible that you have an engraving using overscan thatâs too close to the sides of the machine. Could that be it?
Without more detail itâs going to be hard to suggest what might be wrong. Can you show an image of your LightBurn window before you try to run the job?
If we uncomment the Gcode seems is that M8 command thats causing trouble
In your layers do you have air Assist on? @LightBurn shouldnt this command simply be ignored by Grbl?
ALARM:2 is out of bounds. Line 5 is the 5th line with content, ignoring comments, so one of these is the bad line:
G0X324.67Y146.01
G0Z60
If counting from zero, itâd be the G0 Z60 line - Does the Ortur have 60mm of Z travel? Iâm assuming not, so the user likely has the Z enabled, and either has a very large âmaterial (mm)â value and is using absolute Z moves, or has a large Z offset in the cutting layer.
@daverage - You should enable âRelative Z moves onlyâ in the Device Settings, so the Z will stay where you start it unless told to move otherwise. That will likely help.
