Different revisions. They’ve released K1C (with different parts in some places) after K1, but they didn’t do an official refresh for Max (which got some of the upgrades like new nozzle) silently. And there were at least a few extruder revisions in between.
I’ve done a similar thing using IKEA Samla Box (fits 6 rolls). With a few boxes of silica gel (dried periodically in my filament dryer) I can get it to stay relatively dry for a few weeks (goes from ~15 to ~25% in a few weeks).
Helper script (2nd link) is easier to use. simple AF (first link) is fully open source, but requires you to use another bed leveling probe - no open source „driver” for prtouch- the built in one (which is slow and not terribly accurate anyway).
I don’t think so. I haven’t built mine yet. JSN comes with a pretty long cable, so you could but just the probe in your well and keep ESP above ground to have Wi-Fi. You could battery power the ESP32 and use deep sleep to conserve battery (you don’t need to have probe reading every second or minute, right?). You could even try to use solar power to charge the battery. Possibilities are endless.
I’m going to try to mount a probe in a sewage tank - I have a few cables left leading to it. That means I don’t have to worry about power or Wi-Fi - Esp32 i going to be at home, the probe and its control board inter sewage tank.
They are at least resellable, which would not be true of pure digital. One could also argue that even regular media don’t always contain all the content needed to run the game (require a download to start it), and are not fit for archival purposes. I agree with other points. To me it’s especially stupid that you have to pay for your storage, and microSD express cards are not cheap (and games are getting pretty big, which is not weird).
I had them replace it 3 times before I got a working one. By the time it was delivered I’ve returned my Ender 3 V3 KE and got…K1. I am much happier with it though, and I’ve even mounted that CR-Touch on it at się point;)
