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?
What's your start gcode?
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.
