The height map clear does not appear to work.
Based on the firmware the defect must be in the DWC UI code and not in the Firmware Clear Map Code.
Because you need to disable the mesh to set Z probe offsets and level the Z, setting the initial bed level height was confusing or just wrong.
@rflulling Thank you for posting; I've updated the Dozuki to reflect the necessary knowledge.
Given the dynamic way RRF works, if you can sense temperature on that port, you should be able to control with it / create any sort of tool. So plug in a generic thermistor and try to read it then proceed to figuring out how to trigger chamber control (probably by turning a fan on using thermostatic control)
