Homing
I starting homing. The printer starts moving and then it just keeps skipping. It never homes.
Let's see if your limit switches works.
Run:
M18 X Y; This disables the CoreXY (motion) motors
Slowly move the extruder head to the center
Run:
M564 H0; Let's you move the motors without homing.
G91;
Manually engage (press down) on the X, Y, and Z Limit Switch. We recommend using tape.
We discourage using your fingers. Do so at your own risk.
Run:
G1 Y100 S1;
G1 X100 S1;
G1 Z100 S1;
If the extruder moves forward or backward,
- The Y Limit Switch is not working.
If the extruder moves to either side,
- The X Limit Switch is not working.
If the bed moves down,
- The Z Limit Switch is not working.
I am calibrating my z endstop value. After I home Z, the Z endstop value is not what I put.
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?
YES
NO
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.

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"
M203 X# Y# Z#; Maximum
Is this value smaller than your new Z Endstop Value?
YES
NO
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.
Continue reading.
Home the Z.
Run:
G29 S2
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.
