Short answer, they click occasionally.

Long answer - the bed is a good fit, when cold but doesn't need to be tapped into place. They are ABS so they give a little, and the way they are mounted across the verticals means that the outwards force, when the bed expands, is distributed between the two supporting 2020 extrusions.

I don't know if its a potential source of problems, but if it is I haven't detected any yet.

I'm thinking of adapting your design and taking the screw holes for mounting to the frame and making them slotted. Just a small slot, like 0.5mm and angled properly so that it can slide a bit if the expansion pushes it to do so.

That'll work but it's really not a big problem. I made the mounting holes a bit wider to get it to fit, but slots would work also. Let me know how it goes.

could you say us if you are happy with nimble?
could you show us the final result with it mount

Hi I have a nimble but I haven't got around to fitting it or using it yet. Been too busy making piezo sensors.

where do you buy you piezo?

From RS components. Please read all about it at www.precisionpiezo.co.uk, and there are several piezo threads here also in the general forum.

do you have the ref from rs components for the good one?
it s very interessing project and very accurate sensor!
now we need an electonic module to add with this sensor as i can see

i have this for my big delta project..and clone hotend v6
could you say me which is good for this effector?

Hi rs stock number for 20mm Piezo is 871-1994P

You'll need a pcb, it's available to buy click shop at precision Piezo site above, or you can make one see the resources page.

i will buy pcb on uk page
could you say me which file i need to print to be compatible with my effector?

No not for certain, I don't make a sensor specifically for that effector. But if the holes are 25mm spacing the screw mount module will fit. You can always alter it in cad before printing.

djdemond:
are you design something like this for you delta : a Kossel Linear Drive Belt Lower Cover
[www.thingiverse.com]

and this

you machin will have a better looking

Thanks, the lower one might be useful, the upper one would be a waste of time if sits on a gable and the top cannot be seen.

i search this kind of design to enclose mine but i can t arrive to find the stl file
if someone has find it ccould be great to share
