Ok so I brought the linear rail for the S9 and a pair of Limit Switches as well as a Sculpfun Cam500 camera…
The installation of the Linear Rail went better that expected, I then installed the limit switches…
I then fired the laser up to see if all was well… But oh no… The x axis does no move…it tries but no go…
Switched the wires on the motors and the motor for the X is all good, so I thought it might be the Limit Switches so I disconnected them from the laser, no good so I then disconnected them from the Board, well that went better and now the head moves when I used the Move window…But when I try to frame from the Home position all hell breaks loose…
I have tried to move the home position from the bottom/Front Left to all 4 corners and I get not what I expected…
I have not tried to change the Firmware for the switch, every time I read up on it I get confused, and the I have find a way of doing that from a usb or SD card cause know internet in the workshop …
I know with out the switches the camera can’t be used so have not even tried to install that yet…
That’s all for now if someone can shed some light on my wee problem or more info is required…bad weather here for a couple days so probably not be able to get to the shop until Thursday, maybe…
I’m now 73 so go easy people and also have tendonitis in both hands…
Are your switches wired normally open or normally closed?
The switches are at the moment disconnected from the board
Check if the switches are working and for correct connection.
With laser off an disconnected from PC if you jog the laser head by hand at usual home position then connect everything back how the laser behaves then?
Also check this guide for the S9
Ok now I’m annoyed…I turn all off, Homed bottom/front left as normal… Turned on and tried to Frame a small circle in middle of table…Laser moved from the frame about 2 inches then proceeded to frame a small square shape then stopped…
Tried to video the few seconds but my video on the phone is not playing ball…
If I plug even one limit switch in on the rail and not to the board the laser tries to move but does not…
I know if I have not set up the firmware the homing will not work but if the switches are not connected to at board should not the laser work…
Not sure what you mean. You are saying that the switch you plug in is not electrically connected to controller?
Exactly right… When I first changed the old rail for the new linear rail I also put the limit switches on, but after nothing wood work I disconnected the wires from the switches and the board and still the laser a couple inches done a frame and stopped…
I mean the laser was working perfectly ok without limit switches and the old rail but thought an upgrade to a linear rail wood be nice, so no messing with wires used the some set I had before the change… so…?
If your S9 has an old board, you have to flash the firmware with one that has home cycle enabled, then check the GRBL settings.
In LightBurn console window
Type $I enter
Type $$ enter and copy/paste here the output.
Better always do one upgrade at a time. Once you connected the linear rail, did you invert the x-axis direction? This changes when attaching the rail. Or you need a small inverter cable, I don’t know if that’s delivered with the kit.
Once you try to move the axis, what’s the output in the console window? If there is a settings problem, you should get errors there.
I’ll try this tech is not for me, looked at doing the flashing thing watched a few video’s and my head started to spin…
So thought I wood leave that and concentrate on getting the laser to work again…
Now as I have no internet in the workshop every thing I do will be put on a usb and brought into the house…
So here goes Started the computer, switched on the laser and tried to frame a small square…
Attached are a couple screen shots (hopefully)…
You need to wait a bit for the files to be uploaded to the forum.
Adding to what @misken wrote, if you jog the laser head by hand to the middle of the workbed and then try to move it by using the arrows on LightBurn Move window the move is correct?
Also check Console window for errors.
Lot of us here to help.
$I (letter i) and $$ (double-dollar)
Will have to until the morning, ($I not $1) that’s capital I or small i…bugger…
Will learn one day 
Sorry bout the reply above only way I could upload file…Open Office…
That’s the output I could extract from your document. This does not show any error message while moving, though I will comment below:
$0=10
$1=25
$2=0
$3=0 — you need to check if this is correct after installing the linear rail
$4=0
$5=0
$6=0
$10=3 ------ this should be 1
$11=0.010
$12=0.002
$13=0
$20=0
$21=1
$22=0
$23=3
$24=200.000
$25=3000.000
$26=250
$27=3.000
$30=1000
$31=0
$32=1
$100=80.000
$101=80.000
$102=250.000
$110=6000.000
$111=6000.000
$112=1000.000
$120=1000.000
$121=1000.000
$122=1000.000
$130=410.000
$131=400.000
$132=200.000
As already mentioned, first make sure that the overall movement is ok, use the arrow buttons to check if it moves normally.
Ok people success… Attaching LB file of the setting $I and $$…
Melvin you mentioned the small inverter cable thought that was an extension cable… nothing to say what it’s for…
Anyway that was the problem… now all works moves up, down, left, and right…
Now have to think about the limit switches… but have some work to catch up on first cause it’s going to take a clear head and no other distractions…
any way thanks to all that helped…

Your board is an 8Bit one maybe @misken can confirm this.
your kit doesn’t come with an “inverter cable”. if you did need to invert the x/y travel directions it would just be done in lightburn.
