Likely Causes
  1. Z stepper motor cable connector has come loose from vibration during shipping or use
  2. Motor driver on the mainboard has overheated and entered thermal shutdown
  3. Z lead screw is severely bent causing the motor to stall under load
  4. Cured resin on the FEP created excessive suction force exceeding motor torque capacity
How to Fix It
1
Check the Z motor cable connector on the mainboard for a secure connection
2
Disconnect the lead screw from the motor and test if the motor spins freely with a manual move command from the printer menu
3
Inspect the lead screw for bending by rolling it on a flat surface
4
If the motor stalls during printing, reduce lift speed and increase bottom exposure to reduce FEP suction
5
Clean the FEP film and apply FEP release lubricant to reduce peel forces
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
