Strange output from 9 point calibration

Heyo! I recently got a 300mm lens (Amazon.com: Cloudray F-Theta Lens 300x300mm FL420mm FL380mm M85 F Theta Fiber Laser Lens for 1064nm Fiber Laser Machine Scanning) for my 50W Laser from PerfectLaser (Its a JCZ/Raycus board as far as I can tell) and went to do a 9 point calibration, to some weird results.

At the supposed 300mm working area, the burn did not even frame whatsoever.

Setting it down to 250mm, the burn started to frame but was WAY oversized

I set the calibration grid to 110mm just to see what it would do and it spit out a calibration grid like what is shown in the attached image. the lines are well over 300mm long, and I have never seen a calibration box burn like this so any advice/feedback would be very welcome.

I have set the focal distance already so that shouldnt be the issue

Thanks!

Update: I messed with the scale manually which has helped, but I still dont know why the 9 point calibration is looking like it does. When running the calibration while it looks like this do I measure from intersection to intersection or from where the line terminates to where it crosses the middle line?

Any help would be greatly appreciated!

On my 300X300 lens last time I calibrated mine with 9 point I had to reduce the calibration scale down, and framing still ran the lines off to infinity. Ran the calibration anyway, then adjusted the scale with the scale utility, came out almost perfect. Looks to me like you are just missing one of the steps. Make sure you start in focus.

Here is a thread from the last time I went through it.

Here is the documentation

Ah perfect, thank you so much for your response. Your suggestions seems to have fixed it.

Cheers!
