The first test I’d recommend is draw a 20mm square near home and the origin.
Then Frame it to see if it’s about the right size.
Your X axis lead-screw looks considerably steeper than mine.

hi mate yes i run the 20mm box seem to be ok

Saw your video. Seems to me an offset issue. I tend not to think it’s a calibration issue since you can frame your perimeter correctly using current position.
Can you home and then run these commands in Console and return results?

This indicates that you’re working in a negative coordinate system which could be creating issues.
Run these commands in Console:
$10=0

Power cycle then test.

i tried to do set laser position in the centre of my work and it hit the switch straight away ?
Can you home and then run ? in console and return results?
Also, confirm that home is lower-left on workspace, yes?

I wanted you to enter ? into the Console.
I thought I saw the machine homing to the front left of the bed in the video. Is that not the case?
Also please confirm that your bed size is 500 mm wide by 400 mm tall.

hi mate sorry yes front left
sorry about misunderstanding on the (?)
this is after homing
<Idle|WPos:0.000,0.000,-1.000|FS:0,0|WCO:-499.000,-399.000,0.000>
ok
in the screenshot above the outer box is as far as my machine will go before hitting switches
my maximum travel is 260mm left to right
Hmm… in that case I do wonder if @JohnJohn was on the right track about calibration. I don’t understand how you were able to use current position for the perimeter then.
Change these to:
$100=80
$101=80
$102=80
Rehome and retest limits. Then draw a square with specific dimensions like 100x100mm. Then measure the burned dimensions.
We may want to fix your max travel dimensions and the offset later since your size in GRBL is currently 500x400 mm.

Something is not lining up for me. Let’s start again. Let’s put the steps/mm back to original.

Then type this into console:

Can you return the result? This should have made the laser head move 10 mm right and 10 mm up. Is that what happened?
