Thanks guys for your help. Sorry for the pic quality, the device is so small I had to zoom a lot with my phone. The switch is a tactile one, the plastic body is missing, and what you can see in the center is where the contact is made : when the swit

Unplug the tactile sensor and check the switch with an ohm meter. If the tactile sensor switch is good go in one of the drawers in the back of the machine and with the help of your schematics find the opto-module that controls the tactile sensor circ

Here's a few ideas: If it has one, make sure the flexible coupler set screws are tight. Replace the tactile switch (often these appear to work fine in I/O but do not work properly in production). Clean and oil the tactile plunger if it has one. M

Sounds to me like the driver for the tactile is not working. The tactile has three components to it. The first is the switch, the second is the pneumatic up/down actuator and the third is a small motor in the tactile assembly. The motor has a driv

Make sure the housing for the switch can move up and down freely (no lose parts/screws and the lead screw is clean and lubed with some light oil). I've had a tactile housing come loose from the lead screw = limit errors - it should be tight with no

I've got a small smt board I've already got working prototypes of, which uses a tactile switch. I've got another much less expensive tact switch of similar size that I had avoided due to a difference in actuators I originally had no way around. Now I

SWAG is prolly right. You can verify the tactile sensor by watching the machine carefully. When finding the stencil height, make sure the board goes all the way up and touches the stencil to trigger the tactile. If it doesn't, then something is wr
