Flashforge Guider II / IIS Spare Z-Axis Stepper Motor – Vertical Axis Drive

Your bed's not moving up and down like it should. Maybe it's stuttering, skipping steps, or just dead. The Z-axis stepper motor takes the most mechanical abuse on any FDM printer — it's carrying the full gantry weight every single layer. This is the direct replacement for the Flashforge Guider II (TL4240) or Guider IIS (TL4239). Swap the motor, re-seat the leads, and your vertical travel's back to where it should be. No hunting for a generic motor that's 'close enough.'
