@Phaedrux i saw but they are years old at seams no one from thoes threads reply anymore, thats why i want new input.

I have two Brand new Duets still in the box and as soon as I have the machine ready I will give it a try, however I am looking at an uphill struggle. My forte is mechanical Engineering and I would need to scratch deep to find what I need to do, however this site has a goldmine of information and I will try to manage.....

@oliof well for starters "me not making it work" does not in any stretch of imagination means "no one can make it work" 😄 😄 😄 😄 ... but I have my reservations about repeatability and precision as for e.g. in theory piezo disks should be the perfect endstops and should be way more precise and more repeatable than anything else out there but I know ppl that are finally happy with their printers after moving away from piezo... same here, I don't think it's solving "a problem", there's enough great sensors out there today, adding a new way to detect boundaries is not bad thing but hardly something that we need. with all the fancy stuff we did in 12 years of reprap project I don't see a significant increase of precision over simple, cheap, microswitch 😞

I aggre with ther thermal cutout. I was thinking of a bi-thermal clickson that needs to be fisicaly reset if max temp is exceeded what is the highest temp one would have too hit with a heated bed,, what max should i shoot for ??
