My bed is sat on 4 corner springs. Will this work with the under bed setup? I only ask because the PCB only has 3 piezo inputs...............

Also, could we have a drilled piezo disc sandwiched between the the spring and the carriage or does it need a more elegant solution
?

You can work with 4 corner springs But, and it is a big but, with 4 mounts the forces on the springs will mostly be trying to bend the plate, or bend the carriage and one of the adjusting nuts will likely be looser than the others. If you using sensors which have a very low compliance this is likely to make the slightly loose one too sensitive. Although the design may force you to have four mountings it is something to be avoided - like smoking or running with scissors - three mounts is much better.

Like this?

This arrangement works quite well with just a little caveat: Make sure that the drilled hole does not have burrs around the edge as this will make for some strange triggering

Thanks, 4 is what i've been given so i'll have to live with it for now. Yes that design was exactly what I was planning to do. Do you have a link to the pressure pads? Also what size piezo would you suggest?

Hi,
I have a titan/aero bracket design for piezo its here:
[www.thingiverse.com]
And a different idea which is very much a beta, I have one on my corexy its working okay:

where did you add that? On the back of the motor? It's not really possible in my case because there's nowhere to attach unless I move the motor to the front, what I am afraid of unbalancing stuff.
I've been doing that, but still not a lot out there.

No, I'm using a Bowden setup on Tronxy X5S (cheap corexy from china) mount is similar to a CR10. It's probably more straightforward to just get a 20mm sensor and use the groovemount, but I'm a sadist.
