Restarting the software should clear the error that caused the software to freeze.
Positioning controls stop responding, but the remainder of the control software
still functions
This problem is caused by a communication error with the positioner. Restart the software. It
should not be necessary to re-home the positioner.
The positioner does not return to the back left corner when homing, or gets stuck
While rare, it is possible for the motors to experience excessive load when returning to home, or
to get stuck at the outer limits of travel if the lubrication has become unevenly distributed. If this
happens, make sure no objects are blocking the travel of the mechanical stages, exit out of
SonoGuide, and turn off the control electronics box. Manually push the X and Y stages back and
to the left by 2-3 centimeters. Restart the control electronics box and restart SonoGuide. This
should allow the stages to home properly once again.
Dispenser cracks or shatters
As the dispensers are very fragile, you must be careful to ensure you are not putting too much
pressure on the dispensing tip. Sonoplot suggests moving the tip down to a short distance
above the surface, then stepping down in 10 micron steps until a fluid bridge is made between
the tip and the surface. It will require some experimentation to determine the voltage required to
dispense the fluid without spraying. Also be sure that you have calibrated for the cant of the
surface, to ensure that the tip does not drag against the surface during your dispense pattern.
The impedance scan shows no strong resonance, or otherwise does not look like
the examples in this manual
There are two possible problems here, which can be differentiated by the characteristics of the
impedance scan:
If the impedance scan starts at about 980 ohms and decreases linearly, with no major features,
the dispenser is not connected to the electronics and an open circuit is being measured. Check
that the RJ-11 (telephone) plug at the end of the dispenser is snugly fitted into the black RJ-11
socket on the front of the dispenser. It is also possible that the cable connecting the dispenser to
the electronics is unplugged. Check that the gray RJ-11 cable is plugged into both the black
RJ-11 socket on the front of the positioner, as well as into the back of the control electronics
box.
