Hi!Nice cool instructable!One thing, you didn't mention a need for an external output device, e.g. speaker or headphones, connected to the RPi, which I presume was a logical assumption, right? Cheers

Makes sense, yep.

Hey! Nice and detailed instructable! Defo will come back for info when doing my Nixi project.One note, shouldn't line "11th pin is the common cathode" actually refer to common anode? Cheers and keep up the good work!

I've been looking into doing this, thanks for the solution! : ) works like a charm.

Glad you have considered that, shame you haven't mentioned about.Physics and behaviour of many materials under various temperatures told me about necessity of including that during calibration of a typical FDM printer (that has got a metal extruder and glass/aluminium bed).Your device might be printing decent objects without heating during calibration, sure. Some other (3 brands out of 5 I work with) show drastic decrease in precision when done without. Depends what you want to achieve.Antzy Carmasaic talks about that in his project (last section).ps. Don't take this as an attack mate. Keep up the good work.

kd8bxp, yep. I'm fully aware of that. Just trying to figure out if OP is too potentially maybe included that in the project as a form of limitation.

Hi there dnicky2288. Can the FSR sensor be used while the nozzle and bed are at desired printing temp (let's say 200C and 60C for example)? Generally temperature does effect resistance itself and hence measurement of it. And doing the levelling with your tool without pre-heating bed and nozzle in most printers won't result in accurate positioning because those materials expand with temp.Have you considered that?Cheers
