Discussion
Adjustable height range of the filter chain in IY
- The condition of F1 stepper motor is the same as the F3 in IX. We tried to move the motor with the stand alone driver, but the FR is still not working.
- The motor is still not working?
- The FR slider is stuck?
- The range of BF is too small. Check the mechanical stopper.
- Tune the F0 more to lower frequency (now 0.4Hz) in order to extend the range.
