What i see on the screen does not match what my machine is trying to do. When I choose the marker position it goes and hits the limit switches of the front of the machine. The display coordinates appear to match the lasers position. However whenever I place an item in the middle of the design area and set start from to absolute coordinates it does not move to the correct spot. It ends up hitting limit switches instead.
Does you Ruida boot and home properly? It should not hit anything if itās properly configured. It āknowsā the machines boundaries.
How did you configure the āDevice Settingsā and the āMachine Settingsā?
Where does your machine āhomeā on power up?
Is that the same corner you have it configured?
Jack,
I think he may be using āhitsā figuratively vs literally.
From reading the OP Iām not sure if he has a diode or CO2 laser.
To be able to help we are going to need more specific information including the type of laser and what coordinates he is telling it to go to and exactly what the laser head is doing.
The profile says āDSP Ruidaā for the controller, so for this, type of laser isnāt really a concern.
If itās a properly configured DSP it should not even attempt to move the head as it āknowsā the machine limits will be exceeded. Thatās where you get the āslopā error.
Something else is going on or I misunderstood his description.
Is this a diode laser? What version of Lightburn? When did you last upgrade?
Has this ever worked or is this a new behavior? Or have other things worked and this is something different youāre trying to do?
Just to see if I follow your postā¦
You turn on your laser and it homes correctly to the front left corner where the limit switches are. The location in Lightburnās Move tab says X:0 and Y:0.
Correct so far?
Then what do you do? Screenshots will be helpful.
One other thing to try is while the head is homed, go to the move tab and type 300 in X and 400 in Y the click Go.
What happens and please be specific as possible.
In fact, this is a normal phenomenon, because when starting the cut, X,Y, axis need to go back to the origin, before entering your design area.
You do realize this is the Lightburn forum, not RDWorks.
The Docking Point feature, if enabled in the controller, will return the controller to the docking point after each job, regardless of software.

So honestly I just got the laser and I am completely in the dark on knowing how to get everything configured like I need too. Iām used to the Diode lasers and so this is something totally new to me. Something is way wrong though because when I use the waypoint to move the laser around it just takes off to the front left corner no matter where I click the waypoint in light burn.
You have a configuration issue from what I can see.
Is this a new machine?
Did you go through the Lightburn Ruida configuration and the Coordinate and Job Origin documentation?
I am having issues with the laser grinding against the left X Axis and making an awful grinding noise and itās like itās not reading the correct size of the bed. I can reset the XY Axis but every time I turn the laser off and back on again it starts this all over again. Iām not seeing anything on the internet of how to fix the issue. When I reset the XY Axis everything works like itās supposed to. Yes this is a new machine. Thanks again
Have you contacted the seller? If you think itās not reading the correct size of the bed, have you tried creating a new profile in lightburn with the correct sizes on the correct axis? Your Ruida controller might not have been setup properly and you might need to adjust x and y axis size there as well as home location. Your limit switches should stop this from happening by default.

Youāve pretty much lost me. Iām not sure I know what the problem really isā¦ Trying to followā¦ The basic idea is the same for any cnc machine, same concept as the your LED laser
If itās new, did it ever work?
If so, what did you change?
Apparently, it doesnāt home?
It doesnāt āreadā the bed size. It knows itās bed size from itās internal configuration and āhomesā to know itās 0, 0 position. If it canāt āhomeā it doesnāt know where it is.
If it canāt home, thatās where you start your trouble shooting, since thatās itās first move and itās failing.
This problem is most likely with the controllers configuration, not software.
Relax and answer these questions posed to you. It will simplify your āordealā 
We call them limit switches, but they are home switches on the Ruida. Their only use is to tell the machine where 0, 0 is. If they trip while the machine is in normal operation, the Ruida will ignore them. Iāve reached in there and tripped themā¦ nothing.
On my grbl machine, they do halt it during operation.
Even the Lmt*+/- inputs, donāt appear operational unless the controller homes properly. It seems pretty handicapped if it canāt home.
