No worries 🙂
Yeah I might get a sheet just to try with the piezo sensor, but so far I'm sticking with printbite.
Which interestingly although its fairly tough a 250 deg C nozzle driven hard into it during a headcrash, which I had a few of during developing the piezo sensor, will leave a hole in it, I have about 3 or 4 holes, tried filling them with abs juice, which works but gets pulled out with a print.
