Pro Has No Adjustment for the the HOME Position?

[mrjayd]

OP and others, there is nothing wrong with your machines.

There are two Z-axis "zero" positions:

• a "physical zero" position determined by feedback to the firmware from from the optical limit switch  at the base of the Z-axis column;
  
• a "logical zero", an offset from the physical zero, set by relocating the trolley from the physical zero and pressing the "Z=0" button.
  

Pressing the "Home" button always moves the trolley to "physical zero", however a gcode positioning command calling for positioning the trolley to "0" will move the trolley to the logical zero position.

Moviement to the "logical zero" (as saved by thr "Z=0" function) can only be achieved via gcode commands.

More about this in my post here...

But there IS something wrong with our machines meaning we shouldn’t have to go through this on a new machine fresh out of the box. I have had Anycubics and Phrozens and NEVER had these types of issues.
