Dimensional Accuracy Calibration

Remember, there is:

• No Z-axis calibration setting.

I’ve not tried this, but did bookmark a recent post by @RocketSled:

I recieved a solution from Bambu to adjust Z steps / Z compensation

In the start G-Code you have to add the following

M290.2 Z(Value) M500

with Value being expected height/actual height.

So mine was expected height 20mm / Actual Height 19.9009 so a value of 1.00497967etc

I tested it out and it did compensate and brought my Z height of the test cube up to 20.0152

It will also work for X and Y as well using the same line of code but swap the axis from Z to the one requiring compensation.

Possibly this M290.2 code is being used by OrcaSlicer to provide shrinkage compensation for X-Y and Z?
