It is composed of:
- printed rail that is hooked up at the bottom of the ERCF V2 by 2 arms. This can also be a 2020 extrusion. The rail is designed for 13 gates + bypass, But can be cut in the slicer to the needed length. The bypass position can be anywhere.
- the back side of the rail gives the possibility to hook up a small box that can receive a PI Pico in case the MCU does not have enough inputs for the Pre-Gate switches.
- The back side of the rail gives also the possibility to attach the wires with tie wraps.
- on top of the rail, comes the Pre_Gate sensor guides
- in the guides, the Pre_Gate sensor body can slide freely in.
The Pre_Gate Sensor body.
- This pregate sensor fixes the false triggering issue present in the other Pre-Gate sensor known to date.
- the ball is at 90° instead at of bellow the filament. Thus the ball can't see the notch ground in the filament by "bad" load.unload. This makes it more reliable.
- The switch is installed with its lever, and therefore, the trigger point can be adjusted by bending the lever a little bit.
- 2 M3 inserts
- N+2 M3 T-Nuts
- N+4 M3x8 SHCS
- N 5.5mm ball bearing
- N Omron Switches D2F with lever
- 2xN+2 M2x10 Self tapping screws (2 are for the PI Pico box)
- N ECAS or magnet holder
- N 2 pins Dupond male connectors straight or angled
