If you have an older APQS machine, make sure your motor speed is set to above 7. If you have an unregulated Gammill machine, check that the green light is on in the front. The stitching switch for the IQ is attached to the front of the machine, so the front must be activated for it to stitch. For other machines, or if this does not help:
Remove the bobbin and the thread from the needle and take-up lever.
Go to Utilities -> Configuration -> Interface Setup/Test (System->Interface Setup/Test with older program versions) and do the following:
- Touch the Start Switch button several times. The machine should start and stop as expected. If not, increase the Start Pulse Duration by 50 at a time and try the button again.
-If the stitching does not start, listen to the interface board at the back of the docking station. Touch the Start Switch button several times. Do you hear clicks when you touch the screen?
- If there are no clicks, push the cover on the interface board toward the docking station, so it pushes the orange-colored relays back in their sockets. You may want to remove the cover and push the relays by hand. Repeat the Start Switch test.
- If this makes the switch work as expected, reduce the Start Pulse Duration to 300.
-If you hear clicks, but the machine does not start/stop, gently tug the wires in the six-position green screw terminal to see how firmly they are held. Pay close attention to the RED and BLACK wires.If you find a loose wire, loosen the corresponding screw, push the wire all the way in and tighten the screw.
- If there is still no stitching, unplug the six-position connector and use tweezers to connect together the screws that hold the black and red wires in the connector.
