I need some way to quickly, ‘cheaply’, reliably and repeatedly to measure distance……
There’s quite a few ways of measuring distance, including the following, often used with arduinos / by hobbyists
- IR bounceback
- Visual / camera analytics
There’s some newish widgets out there nowadays called ‘time of flight’ sensors….similar to part of how Lidar works
Googling these, seems there’s a fairly cheap one called a VL53L0X…..

Levelling 3D printers almost seems like some form of witchcraft..….Doubly so when you have a small amount of mechanical knowledge and have some electrical PCB tinkering ability
The Wanhao D9 is a Prusa style printer – it has a moving bed and a fixed gantry
A slight difference is that the D9 has Dual Z axis stepper motors – BOTH sides of the Z axis are driven, which adds another dimension to the levelling whajmacallits.
