Machine flips toggle-switch to Off position, but doesn’t retract: red LED lights up and the motor turns counter-clockwise. Machine stops after switching toggle, won’t retract finger, green LED won’t light up. Solution: Micro-switch lever may be bent causing it always to be depressed. Carefully bend lever of micro-switch away from cam so that switch will operate correctly.
Green LED is dim or doesn’t work: you’ve most likely soldered one of the LEDs in backwards.
LEDs are working backwards (green lights when red should, and vis-a-versa) You’ve soldering the LEDs in the wrong location or the polarity of the LEDs are backwards.
If you made a mistake installing the LEDs, do not try to unsolder them to fix this problem because the pads/traces may lift from the board. Instead, clip the LEDs off at the bend on the leads, and resolder at that location.
Slow Motor/Dim LEDs: use fresh alkaline batteries, not re-chargeables.
Motor not strong enough to flip toggle switch: wrong shaft on motor is being used. Use shaft that has the ‘bump’ beside it.
Finger slides off Toggleswitch:
- Ensure motor is screwed tight and flush to motor mount. DO NOT OVER-TIGHTEN SCREWS.
- Ensure Cam Disc and Finger are fastened securely to each other, and to motor shaft.
- If Finger still slips off of the toggle switch, a small ‘shim’ can be inserted between the finger and Cam Disc in order to further align the finger to the toggle. (In plainer language: A tiny bit of paper folded up and put in between the Cam Disc and Finger, correctly positioned, will correct this problem).
Machine stops/shuts off too soon, leaving the finger holding up lid: You may have installed the microswitch backwards. The machine will work but the finger will never fully fully retract if you get the microswitch wrong.
