OctoPrint-FixCBDFirmware VS Octoprint-Smart-Filament-Sensor

My Must-Upgrade list without even going to advanced upgrades like dual extrusion. * Off the bat, you will want to upgrade to direct-drive if you do PETG or similar. * Off the bat, upgrade the belts to something like https://smile.amazon.com/gp/product/B071K8HYB4/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 (Order it at the same time as the printer, don't waste your time on the original belts.) * Off the bat, you will want to buy some corner brackets to stiffen it up - I used 11x of something I had on hand similar to https://smile.amazon.com/gp/product/B07VW9H99P/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1 and printed 4 of https://www.thingiverse.com/thing:4601135 * If you are using Octoprint, it will not communicate without the "Fix CBD Firmware" plugin (https://github.com/OctoPrint/OctoPrint-FixCBDFirmware)

and this? https://github.com/maocypher/Octoprint-Smart-Filament-Sensor

Use this type of sensor and hook it up to the Raspberry rather than to the printer. It's much easier and there's no firmware flashing involved. Also, if you print from Octoprint you must connect it to the Raspberry anyway, otherwise Octoprint would not know when the filament runs out.
