{"product_id":"emu-psf-proportional-sync-feedback-sensor","title":"EMU PSF Proportional Sync Feedback Sensor Set for EMU Sync","description":"\u003cp\u003eThe PSF swaps the two switches in the EMU Sync for an analogue sensor that reads where a magnet sits in the slider. Instead of just \"tension\" or \"compression\", Happy Hare gets a value from 0 to 1, with 0.5 as neutral, so it can keep the gear motor and extruder properly in sync and home to the extruder without a toolhead entry sensor.\u003c\/p\u003e\u003ch3\u003eWhat's in the bag\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePSF PCB\u003c\/li\u003e\n\u003cli\u003e2× ECAS04 bowden couplings\u003c\/li\u003e\n\u003cli\u003eSpring, 0.4 × 6 × 25 mm\u003c\/li\u003e\n\u003cli\u003eMagnet, Ø4 × 15 mm, N35\u003c\/li\u003e\n\u003cli\u003e4× M2×6 SHCS\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNot included: the printed EMUSync PSF housing.
