Purge line runs on using Octolapse

Hi i'm fairly new to the octoprint/lapse, during the purge line at the starting of a print, sent via octoprint the purge line runs as normal but when it get to the end it jumps on causing the Y axis to hit the front of the rail?

Which printer?
What's your start gcode?

Hi Thank you for your reply, below is the requested info.
Printer is Ender3 v2
Start G-code

I don't see anything wrong with your settings

Please upload a serial.log - just of the start part when it happens. You can cancel the printer right after the collision.
