Homing Z: Weird Z Endstop Values
Problem
I am calibrating my z endstop value. After I home Z, the Z endstop value is not what I put.
Solution
Your new z endstop value may not be saved.
Let's check what your current Z Endstop Value is.
Go to Settings. Then click the System Editor tab. Open the machine_zendstop.g file.
Scroll down to the last line.
Check your Z Endstop Value. Is this the calibrated value?
Change it to a new value.
Click "Save Changes" button.
Home the Z.
Check to see if your Z Endstop Value is correct.
If not, continue reading.
Your machine boundaries may be too low.
Let's check if your machine boundaries are interfering.
Go to Settings. Then click the System Editor tab. Open the machine_axisdimension.g file.
Look for the line labeled " Maximum"
Is this value smaller than your new Z Endstop Value?
This value MUST be at least 0.5 mm above your calibrated Z Endstop Value.
Add 0.5 mm to your new Z Endstop Value. This is your new Maximum Z Value.
Change the Z value to the new Maximum Z Value.
Click "Save Changes"
Home the Z.
Check to see if your Z Endstop Value is correct.
If not, continue reading.
Your mesh compensation may be changing the value.
Home the Z.
Run:
The Z Endstop Value should now be the calibrated value.
Mesh compensation is changing the value of your Z Endstop Value.
Proceed with printer operation.
