  • 42 - Prusa Error Codes: Reading the Number, Fixing MMU Jams

    Every Prusa error screen on the MK4, MINI, XL, CORE One and MK3.5 carries a five-digit XXYZZ code that tells you the device and problem category, and for MMU2S and MMU3 owners the 04xxx family shows whether a stopped multicolor print needs a cleaned filament path, a checked cable

    In this episode you'll learn:

    Newer Prusa firmware on the MK4, MINI, XL, CORE One and MK3.5 shows the error name, a short description, a five-digit code and a QR code that opens a dedicated Prusa Knowledge Base article for that exact error. The code follows the XXYZZ pattern; Prusa's own documentation uses 12201 as the example, a MINI bed heating failure shown on screen as 'Heating failed bed'. The first two digits identify the device, and 04 is reserved for the MMU unit (both the older MMU2S and the current MMU3); the third digit is the category: 1 mechanical, 3 electrical (typically motor drivers), 4 communication, 5 system states including incompatible firmware. 04402 is the general MMU communication error and 04504 is a firmware update request; mechanical errors in the 041xx range are the most common in practice, usually triggered when the FINDA sensor or the extruder filament sensor does not see filament where expected. The most common cause of MMU jams is a badly formed filament tip after it is pulled out of the hotend, and Prusa lists which printers show QR error codes in its public Prusa-Error-Codes repository on GitHub.

  • 41 - Under $600 Printers: Open Bedslinger or Enclosed CoreXY?

    Both articles argue that under $600 the real choice is not price but design, an open bedslinger with a polished ecosystem (Bambu A1, Kobra 3) versus an enclosed CoreXY box (K1C, Centauri Carbon), and you should pick based on what you plan to print.

    In this episode you'll learn:

    The Bambu Lab A1 starts at $299 in the official store and has a 256 x 256 x 256 mm build volume, the same as the Elegoo Centauri Carbon. The Creality K1C lists at $599 but regularly sells for around $399 on sale in the official store, so watching for promotions saves real money. In a Rad Dad's Print Lab comparison, the Centauri Carbon was on sale for $265 while the A1 without AMS Lite was on sale for $299. The A1 and Anycubic Kobra 3 are open bedslingers where the bed moves back and forth; the K1C and Centauri Carbon are enclosed CoreXY machines where the bed only moves down. Both the A1 and Centauri Carbon ship essentially assembled with automatic bed leveling, a direct drive extruder, a filament runout sensor, a PEI-coated plate, Wi-Fi printing, and a built-in camera; Elegoo has since launched the Centauri Carbon 2, sold as a Combo with its own multicolor system.

  • 40 - Enclosed Chamber Reality: X1C, H2S, and When ABS Needs a Box

    Both articles center on the enclosed print chamber: the H2S adds an actively heated one over the passive X1C, and choosing a printer or an enclosure comes down to which filaments actually need that sealed, warm environment.

    In this episode you'll learn:

    The Bambu Lab X1C is a fully enclosed CoreXY printer with a 256 x 256 x 256 mm print volume and a passive chamber that holds heat but cannot actively warm or vent it. The H2S is a single-nozzle machine on the H2D platform; dropping the second nozzle's lift mechanism gives it about 15 mm more print height than the H2D, but it loses the 40W laser and keeps only 10W laser, cutting knife, and pen plotter modules. The X1C's lidar sensor scans the first layer to calibrate filament flow, but in practice it proved to be more a specialized add-on than an everyday necessity. Per MatterHackers, ABS needs a nozzle roughly 30°C hotter and a bed about 50°C hotter than PLA, and without an enclosure parts crack, layers separate, and warping appears even far from the bed. PLA has low warping and prints at relatively low temperatures, so it does not need an enclosure, and one can even harm PLA by overheating the hotend.

  • 39 - P1S vs P2S and Why Your Enclosure Won't Dry Filament

    Both articles cover the enclosed Bambu Lab P series, and how the sealed chamber that stabilizes temperature still cannot pull deep moisture out of filament, so a dryer stays essential.

    In this episode you'll learn:

    The Bambu Lab P1S and P2S share the identical 256 x 256 x 256 mm build volume, so the P2S adds no extra print size. Bambu Lab says the P1S stays in production with no plan to discontinue it, so P1S and P2S sell side by side. The P2S raises the maximum heated bed temperature, adds hardened wear parts to the print head, and adds a bigger local screen with onboard storage. The enclosed P series chamber holds a stable inside temperature but will not remove moisture soaked deep into the filament structure. At melt temperature water molecules irreversibly shorten polymer chains, which permanently degrades strength, heat resistance, and chemical resistance.

  • 38 - Bambu Lab A1 vs A1 Mini and Is AMS Lite Worth It

    Picking your first Bambu Lab A-series printer means matching build volume and the AMS Lite multicolor upgrade to what you actually plan to print, not to marketing numbers.

    In this episode you'll learn:

    The A1 has a 256 x 256 x 256 mm build volume; the A1 Mini is limited to 180 x 180 x 180 mm. The A1 heated bed reaches 100°C while the A1 Mini stops at 80°C; both share a 300°C nozzle ceiling. AMS Lite is an open stand feeding up to four spools and switching between them automatically during a print. AMS Lite can act as a backup, switching to the next compatible spool when one runs out so the print continues. The A1 Combo adds the AMS Lite body, four rotary spool holders, and two 730 mm plus two 830 mm PTFE tubes; the bare A1 ships with a single 600 mm tube.
