I lost a print last night. It pulled off the bed.

Jetguy and myself just redid my heater bed when I was making some changes. The wires use to come off the back just like that (Duplicator I3) but we rotated it to do 3 point leveling and brought the wires under the bed and through the base plate then zip tied it there and then did a nice big bend that never bends tight in one spot. this also cleaned up the wiring since all the wires now come out the one corner vs having the main bundle and the heater bundle:

Well I use robot rated cable designed for constant movement.

@Nathan_Walkner Obviously!! but strain relief will stop that.

@Nathan_Walkner My reply was meant to be more tongue in cheek…apologises
