The IdeaFormer IR3 V2 End G-code ran `G28 ; home all`, which homes the Z (belt) and Y (gantry) axes. On a belt printer Z is the conveyor, so homing it runs the belt all the way back to origin, dragging the finished part back under the gantry that G28 has just lowered — the head knocks the print (reported by an IR3 V2 user; the `G1 Y50` lift came after the G28, too late). Replace the end sequence with a belt-safe one: switch to relative mode (G91), lift the gantry for clearance, advance the belt forward one full machine-depth (Z676, the 676 mm product depth) to eject the part and cycle the belt surface clean, then home X only — never the Z/belt axis.
