Anycubic Kobra 3: plan ACE Pro placement and the TPU route

Do not use the feeder for every filament

The left-side recommendation concerns placement, not a way to remove the TPU restriction. Use the official model-specific instructions for the single-color TPU workflow rather than feeding it through ACE Pro. When planning a desk, retain space for the recommended feeder arrangement instead of measuring only the printer.

Anycubic Kobra 3 has the following documented tpu feed constraint: TPU: single-color path, not ACE Pro. Separate the printer’s material route from the optional feeder’s route. For the documented arrangement, check which unit is required, which combinations are allowed and any excluded materials before buying an expansion package. A channel or color-capacity statement describes a configuration; it does not by itself establish that a different generation’s hardware, cable or hub can be substituted.

Retain the original Kobra 3 profile

The original Kobra 3 lists 250 × 250 × 260 mm print space, a standard 0.4 mm brass nozzle and a 300 °C nozzle limit. Use those identifiers when selecting the machine profile or checking whether the nozzle has been changed. The shared Kobra name does not authorize copying a later version’s envelope or replacement-part assumptions.

Anycubic Kobra 3 has the following documented build volume: 250 × 250 × 260 mm. A usable build volume sets the boundary for the object you plan to print. Compare the part in its intended orientation with this envelope before choosing the machine. This measurement is different from the printer’s outside dimensions: fitting the printer on a desk does not establish that a particular part fits inside it.

Anycubic Kobra 3 has the following documented nozzle temperature limit: 300 °C. A hotend temperature ceiling is an operating limit, not a complete material-compatibility list or the setting for every print. Read it alongside this model’s documented filament guidance, nozzle configuration and print profiles. The maximum alone does not establish that an enclosure-dependent, abrasive or otherwise restricted material has been approved for this configuration.

Anycubic Kobra 3 has the following documented standard nozzle: 0.4 mm brass. The same configuration lists tpu feed constraint as TPU: single-color path, not ACE Pro. Identify the installed nozzle and the exact documented replacement route before changing a print profile or ordering a spare. Diameter, material and printer-family fit are separate parts of that check. A listed option is not necessarily included in the box, and an accessory for another toolhead cannot be declared interchangeable from its appearance or nominal diameter alone.
