Alarm: Homing fail approach

[JanKidd0215 (Janis)]

I moved my laser and now I’m getting a homing fail approach alarm. I know the problem is the position X=-1199.99 and Y=-1199.99. How do I reset this to 0,0?

Alarm|MPos:-1199.994,-1199.994,0.000|Bf:15,511|FS:0,0

I have a foxalien reizer laser.

Noobie needs help understanding origins

If your machine homes to the rear-right, and is normally used as a CNC, you most likely work in negative space, and have to set a workpiece origin to use the CNC. In LightBurn, that workpiece origin is the front-left of the machine, regardless of the mode you’re using. If you type $$ into the console and make note of the values for $130 and $131, those are your travel extents (the size of the working area for your machine). Enter this command, but substituting in the numbers shown for ($130) …

Here’s what I am getting when my laser connects and my settings.

@JanKidd0215

• homing fail approach alarm
• $22=0 (homing cycle, bool)

Because homing is disabled in the machine configuration, the controller will not automagically home.

Set $22=1 and the situation may improve.

[MikeyH (Mike Hembrey)]

Then try the G10 thing. My apology for not spotting the Home Fail message.

[JanKidd0215 (Janis)]

It now moves when I click Home, but still slams into the stop trying to get to -1199,-1199. Now here are my settings and what I see when I click Go at Move to Position 50,50 in the Move menu.

The size of your FoxAlien is 400 x 400?
After you reset your work offset you could try thsi option:

[JanKidd0215 (Janis)]

Yes, it is 400 x 400. Here are my Device Settings.
