    Hi,

    I'm researching possibility of building heated chamber CoreXY printer.
    I'd like to achieve at least 100C. Thus I'd like to use watercooled extruder, but I don;t have slightest idea which Z-probe I should use.
    This one caught my attention:
    https://www.precisionpiezo.co.uk/product-page/precision-piezo-orion-kit

    Are there any users of Titan Aqua who have experience wit Z-probes, particularly piezo ones?

    I can't answer your question (our IR sensor is only rated to 85C); but what filament do you want to print that needs 100C chamber temperature?

    I've read, that almost every engineering resin will benefit from heated chamber.
    I've found a study that suggests optimal temperatures in chamber for ABS as high as 88C.
    Coro Technology for their top of the line ABS AT suggests up to 80C in chamber.
    I also have PA6 with carbon nanotubes (by Noctuo) that is quite difficult to handle with chamber temp of about 50C. I'd like to go higher.

    So my minimum is around 80-90 degrees, but materials such as Ultem, PEEK and PPSU are tempting me.
    My last two issues are:
    *belts (I couldn't find 2mm or 3mm pitch belt that will work above 85 degrees), and I don't want to use ballscrews
    * z-probe

    I can live without one, but I'd like to go with table milled from one piece of precision milled 10mm thick aluminum (so no manual levelling, as linear bearings and balls screw nuts will be mounted directly to bed)), and I've read that using stall detection in TMC2660 is unreliable.

    Maybe in this video he talks about the original z-axis sensor....?

    I was curious, so went looking. Have you seen these (2.5mm)? https://bervina.com/heat-resistant-pu-timing-belt-with-silicon-cover-up-to-100-c/ No idea if that would suit your needs. Or for even higher temp, you might be able to go with perforated stainless steel belts. I think that would be a bit extreme, and I have absolutely no idea how practical it would be for the job (or the cost) https://www.belttechnologies.com/timing-belts/

    Not personally intending to build a heated chamber, so this was really just idle curiosity for me. Will be interested in seeing what you eventually come up with though.

    For a Z probe piezo sensor, you could probably come up with something based on this https://www.thingiverse.com/thing:2526978 This is actually on my list of possible upgrades for my cheap i3 clone if/when I get round to it.
