Falcon 2 suddenly homes right after framing. Will not cut or engrave the file

Last week suddenly I uploaded a file traditionally with an SD care (Falcon will not speak to my MacBook Pro latest model, no idea why, they never even met before this) and after file upload alert (green light) I pressed FRAME and it did so where and how it should, then as soon as I pressed start it travels a few inches then returns home, no alerts, nothing. Laser and air lights green, no warnings or alerts sent to the SD card. This is after running pretty flawlessly for a year.

i had this problem on my pc and using Lightburn

the problem for me was on the lazer tab
start from tab
on the buttons to the right hand side i had to move the start from current position to bottom Left at the job origin tab and worked fine for me
