S1 40W with Lightburn will not cut over 292mm in Y axis "SOLVED"!

[Vincent228 (Robert Vincent)]

I have followed all of the instructions on this post ( Setting up xTool S1 with new xTool device type in LB 1.7 and Beyond ) Which worked perfectly, with the exception of one issue still.
I was attempting to cut a square at 298mm high.
It frames perfectly.
But when I hit start, the Y axis will not go bigger than 292mm, no matter what i do.
My offsets are perfect. She frames perfect, but will not cut past 292mm.

I have searched all of the forums, and have found no explenation nor suggestion.
I saw many posts wheere people said they couldnt cut a 12x12" box, which werew then told they absolutely should be able to.
But at 292mm Im getiing just under 11.5" and no further.

Any help please?

Need more information to help. How is lightburn set up for size. What is machine settings for $30 and $31. Are you set for Absolute Coordinates. Does laser home properly. Can you jog laser to 298 x and 298 y

Thanks for the quick response.
Machine is Xtool S1 40W
Size is as instructed (498X Width x 319Y Height).
Machine is set for Absolute Coordinates.
I cannot tell you what $30 & $31 are, as Xtool does not have “read from controller” parameters in either Lightburn or XCS.

And Mostr importantly, i can absolutely jog the laser to 298x and 298 y, I can frame the entire workspace in lightburn. But i have included pictures. You will see I ran a simple square of 100mm X and 298 Y, When it cut, i got 100mm X and 290 Y.

I cant explain it.

I figured it out, thanks to ADHD.
I see there are a ton of people on the forums asking the same, and i have no idea how to get the solution to them.
It was deduced in the xtool xcs site, and a video.
it seems Xtool wont allow you to frame (in this case for a 40W) about the first 18mm in xcs.
But you can still cut.
Now since the laser spot and the actual laser is (according to the xcs site) an offset of 26.4mm, and Xtool wont let you frame in that area, you get 319 - 26.4 which gives you an actual working area to frame 292.6mm.
which is about the max i am getting in lightburn.
Lightburn is big in equaling out the offset when you hit frame, by bringing the laser laser down to the crosshairs (IE the Y offset), you are losing that cutting area, giving you only 292mm (+/- a tenth).
By getting rid of the offset, you gain some cutting area, but not what you want.
Even in XCS, I loaded the 319, and it wont let me cut the full 319, but i did get to 300mm. A whopping 1/4".
BUT!
When i did away with the offset, and accounted that the laser did not cut the top of my honeycomb, I got 318mm on the nose (I couldnt do 319, or you get an error that your cut does not fall in the workspace. So you have to set your bed to 320mm Y).

I found what I needed here: https://support.xtool.com/article/1110
And a video here: youtube.com/watch?time_continue=2&v=Po_K3cZcRqA&embeds_referring_euri=https%3A%2F%2Fsupport.xtool.com%2F&source_ve_path=Mjg2NjY

so is it worth doing away with the offset of the 26.4 (or 27 from what i read here), and do all the math to ensure you fall in the correct spot?

Btw, this photo is taken of a peice of paper board i etched.
I tried for 318mm with the offset off.

And that is better than you get from Xtool XCS, because the lower line at the top where i maxed out at 300mm with XCS.

So, you have options.
But they are not easy, and you have to be very careful not to mark the outside frame of the honeycomb if you go by the crosshairs, as most S1 users are used to.

Just remember, no offset, means your actual cut is going to be 26.4mm higher than the crosshairs.

I also remebered you can turn on “Fire” laser button, and set it to .5% power, so you can see where it is really going to frame and cut. With all that, i was able to burn 318mm.

I hope this helps.
I welcome discussion or feedback.

Glad you figured it out
