September 2024 : I have a new Stock of the TS1401CL listed -

Improved NEW Printed Circuit Board Version 4 layout now available

This version uses the DIP 8pin sensor. A new PCB was designed to accommodate this sensor.

The led display is not included in this listing - just to show that the sensor is reporting the correct filament width.

The 3d printed part is available on Thingiverse.

Please Note! The 3D Printed part is now available as an option - the unit is shipped without it if not selected from the menu. The top tower has been updated to accommodate the new sensor.

Features :

sensor pins are available on 4 pin header

Solid state capacitors

Pre-programmed chip with detection of filament with for 1.75mm or 2.85mm

can be interfaced/connected to any ramps/etc board - output voltage is dependant on the filament width

Requires 5 Volts supply -

If you need to experiment with it and need the chip to be accessible, choose option 1 for a socket on the board. the output and supply pins are available on the 4 pin header.

Concept of 3D Filament Width Sensor.

The unit works by using an led to throwing light in a tunnel where the filament is being pushed. Beneath the filament, there is a 400 dpi sensor that picks the shadow of the filament and the processor translates it to a working voltage. ie 1.75V = 1.75mm filament or 2.85v = 2.85mm filament.

Every Unit is tested before being shipped

Fully Built board with all components and tested by our technician.

The unit consists of :

1 x PCB board with the sensor installed and all discrete components Assembled and tested

1 x High brightness led wired to the board.

1 x instruction Manual to hook it up to ramps 1.4.

Optional Parts

1 x 3D printed enclosure at 40 % infill - select from Option Menu
