After figuring out that 20mm, just ain’t good enough to calibrate, I had a nose around on thingverse….

The largest ‘calibration’ thing I found was the above 280 x 280mm square……..Awesome, that’s good enough, close to 300mm too for maximum calibratory goodness…

Lots of basic printing suggested that the front to back measurement was slightly off…so, finally I’ve decided to calibrate the printer….

By, printing a calibration cube! I’ll do it a little differently and record just a bit more information…I’ll measure 3 points for each axis, giving 9 points for the cube….

Thoughts on technical things

STM

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.
