I must admit, in all the years I've played DF I don't really use pressure plates much. Is it not possible to make a pressure plate send an open signal that includes 0 depth? The game can only lets you select a range between 1—7 which excludes the possibility of activating at 0 depth.

I already found a workaround* for what I wanted to do, but I just wanted to confirm that I haven't missed any obscure method of setting it to 0.

^{*I used DFHack's gm-editor to set the min level to 0. Other less elegant options that doesn't involve DFHack were also available.}

Interesting.  The wiki seems to indicate you should be able to set it for 0 depth…

I just checked versions 0.47.05 and 0.28.181.40d, and while the Pressure Plate interface defaulted to "1 to 7", you could freely reduce it to "0 to 7" (or even "0 to 0"). I guess Toady forgot that setting the thresholds to 0 was actually possible and didn't allow for it in the Premium UI.

thanks for the bug submission, and nice callout OP!

I, too, find very few uses for pressure plates. I'm curious what function your plate mechanism was supporting?

Thanks for checking it out for us!

Nothing fancy, I just wanted it to keep a floodgate open whenever the system is running empty. It still works at 1 depth but the 0 depth was meant to keep the gates open to start things off. The non-DFHack workaround would just require adding a lever to open it manually or dumping a bucket of water over the pressure plate.
