• Developer Mode restores direct control and costs you nothing.
• Community firmware waives your warranty for good, even if you revert.
• Bambu will not promise you can return to official firmware.
• Only the X1 and X1 Carbon have mature community firmware.
• The newest printers shipped locked, with no downgrade path at all.

• Three very different multi-material systems now sell in the same price band.
• Purge feeders are cheap and simple, but throw plastic away on every swap.
• Nozzle swapping skips the purge and gambles on perfect re-seating instead.
• Toolchangers waste almost nothing and carry the most parts to service.
• Count the colour changes in a typical print, then pick the mechanism.

• The Halot X1 keeps the build plate still and moves the vat and screen.
• There’s no leveling step, and tall prints stay steady.
• Its 16K screen matches rivals, but the light behind it runs hotter.
• One reviewer got crisp prints, another got soft, swollen detail.
• It shines on big models and busts, while tiny miniature detail suffers.

• The SuperTack holds PLA on a 45°C bed, 20°C cooler than Textured PEI.
• No outside lab has repeated Bambu’s 300-print durability test.
• Thin brims and skirts can stick so hard they need a scraper.
• Bambu sells it as glue-free, so glue stick is only a release trick.
• It suits PLA and PETG, but TPU damages the coating.

• The X2D has a dedicated chamber heater, so the air is warmed on purpose.
• Parts warp because they cool unevenly, which no amount of bed grip solves.
• ABS, ASA and polycarbonate gain the most; PLA and PETG want cool air.
• The printer swaps between recycled warm air and fresh outside air on its own.
• A hot chamber puts out more fumes, so filtration runs in three stages.

• Bambu firmware blocks slicers from talking straight to the printer.
• The Bambu Connect plugin passes messages along, so OrcaSlicer keeps printing.
• LAN-only mode and developer mode are different switches with different limits.
• Bambu Connect ships for Windows and macOS, with no Linux build.
• Rolling firmware back breaks OrcaSlicer.

• Klipper v0.13.0 brings a new sweeping vibrations test for tuning input shaper.
• The sweeping test replaces the old printed ringing tower.
• The same test finally makes Z-axis input shaping practical.
• Z shaping mostly buys faster Z moves; the print looks about the same.
• The release also adds new sensors, eddy-current probing, and rp2350 boards.

• The XL+ toolhead now cools from all sides, like the MK4S and CORE One.
• Even airflow means cleaner overhangs, bridges and small details on tough models.
• New GT1.5 belts hide the faint ripple lines on big flat walls.
• A borrowed INDX sensor aligns each toolhead about 20 times faster.
• Prices held, and a 249 EUR kit upgrades an existing XL.

• The INDX “hardened” nozzles measure HRC 30 to 32, about half of true hardened.
• They are surface-treated steel with a soft core underneath.
• Bondtech has apologized and admits the nozzles are not abrasive-resistant.
• Boxes and invoices that buyers received still carry the word “Hardened.”
• You cannot fit a real hardened nozzle, because the part is proprietary.

• The Revo High Flow hit 23.5 mm³/s in testing, close to 70% over a stock Revo.
• A brass dome thins the filament and heats it from inside, so it melts faster.
• The melt zone caps your hotend while the heater still has watts to spare.
• Budget about half a watt of heater power for every mm³/s of flow.
• Below roughly 150 mm/s on a 0.4mm nozzle, you don’t need high flow.
