I did build a version of the FFC cable chain based on their electrical designs but found the calibration of the circuit to be very fiddly, as the range of value on the potentiometers that was acceptable was very narrow. + +I've since started from scratch using my own BOM and designs, while including an onboard microcontroller to handle auto-calibration. Given that every 3D printer is different, I wanted this sensor to be as easy and stable as other sensors available on the market, but with the increased performance of a piezo sensor. + +This page may be updated less frequently than the github project, so for the latest information, files, and models, make sure to check there first: + +https://github.com/pyr0ball/pyr0piezo + +Legacy links: +[Original Mount (Doesn't work as well as I'd like)](https://www.thingiverse.com/thing:2712439) +[Original Mount v1 (Doesnt work at all)](https://www.thingiverse.com/thing:2675788) +[Original Piezo + FFC board](https://www.thingiverse.com/thing:2618717) This is a complete redesign from the ground up, but was based on principles and methodologies developed by [PrecisionPiezoUK](https://precisionpiezo.co.uk/resources-osh) From cfa0abcaa5a3fb9236b7c1790dad26d5e9437b02 Mon Sep 17 00:00:00 2001 From: pyr0ball Date: Wed, 9 Jan 2019 17:20:29 -0800 Subject: [PATCH 2/2] Update Readme --- README.md | 3 +++ 1 file changed, 3 insertions(+) diff --git a/README.md b/README.md index 80bd193..2ab7b1c 100644 --- a/README.md +++ b/README.md @@ -24,8 +24,11 @@ This page may be updated less frequently than the github project, so for the lat https://github.com/pyr0ball/pyr0piezo Legacy links: + [Original Mount (Doesn't work as well as I'd like)](https://www.thingiverse.com/thing:2712439) + [Original Mount v1 (Doesnt work at all)](https://www.thingiverse.com/thing:2675788) + [Original Piezo + FFC board](https://www.thingiverse.com/thing:2618717) This is a complete redesign from the ground up, but was based on principles and methodologies developed by [PrecisionPiezoUK](https://precisionpiezo.co.uk/resources-osh)
