Hey does anyone know how to add bed leveling to a borelee 3D printer?

Hey does anyone know how to add bed leveling to a borelee 3D printer? Also does anyone else have a problem with the linear bearing on the hotend having some play making some jogs in a print instead of perfect shape.

grab a sensor, design a mount, re-do firmware - Tom has a good guide for this - https://www.youtube.com/watch?v=EcGFLwj0pnA - you just need to sort a mount out.If you’ve got slop in a bearing, you’re best of replacing it.

Thank you
