| 1 | Prusament · PLAPrusament PLA lists a nozzle of 205–225 °C (401–437 °F) and a bed of 40–60 °C (104–140 °F). Both ends sit under the MK4S and CORE One+ maxima of 290 °C (554 °F) and 120 °C (248 °F). Both printer records store a brass CHT nozzle. | PLA | 205–225 °C (401–437 °F) | 40–60 °C (104–140 °F) | — | — | |
| 2 | Prusament · PETGPrusament PETG lists a nozzle of 240–260 °C (464–500 °F) and a bed of 70–90 °C (158–194 °F) on the Prusament PETG technical data sheet. r/prusa3d 197ialb is MK4 PETG warping, and the comments add a brim, more squish on a textured sheet, and a clean plate. | PETG | 240–260 °C (464–500 °F) | 70–90 °C (158–194 °F) | — | Datasheet | |
| 3 | Prusament · ASAPrusament ASA lists a nozzle of 250–270 °C (482–518 °F) and a bed of 100–120 °C (212–248 °F). The bed maximum matches the stored 120 °C (248 °F) bed. The MK4S record marks the enclosure optional. The CORE One+ record stores a heated enclosed chamber. | ASA | 250–270 °C (482–518 °F) | 100–120 °C (212–248 °F) | — | — |

Load PLA, PETG, or ASA when the spool's nozzle and bed sit inside 290 °C (554 °F) and 120 °C (248 °F), which is what the MK4S and CORE One+ records store. The catalog has no Prusa Mini row.
What fits
Prusament PLA is 205–225 °C (401–437 °F) and 40–60 °C (104–140 °F). Prusament PETG is 240–260 °C (464–500 °F) and 70–90 °C (158–194 °F). Prusament ASA is 250–270 °C (482–518 °F) and 100–120 °C (212–248 °F). All three sit on or under the stored maxima. PLA, PETG, and ASA are the hubs. Prusament PC Blend lists 265–285 °C (509–545 °F) and 100–120 °C (212–248 °F), so that temperature window also fits. Hardened nozzle is blank on PC Blend. Prusament PA11-CF lists 275–295 °C (527–563 °F) and hardened nozzle is true, so it does not fit the stock brass nozzle or the 290 °C (554 °F) maximum. Carbon fiber is that limit.
The MK4S record says the enclosed chamber is not included and that an enclosure is optional. The CORE One+ record says the chamber is heated and enclosed. ABS and ASA enclosures is the chamber question. ASA printing and warping are the material guides.
What the threads are actually about
r/prusa3d 197ialb is MK4 PETG lifting. The leading comment wants a brim, an extra -0.05 of squish on the textured sheet, and a sheet scrubbed with soap degreaser and then isopropyl. Another comment asks about drafts. A third says enclose four sides and leave the top open. That -0.05 is the comment, not a stored Z offset. PETG printing is the material page.
r/prusa3d 1ilu19b asks why a CORE One spends about 7:40 absorbing heat before PETG. The leading comment says an MK4 without an enclosure has only the room to heat. Another comment says the gcode is waiting on a chamber temperature.
r/prusa3d 1im3lgv asks if a CORE One should print only PETG. A comment says the machine can print from PC to ASA to PA, and that PLA is the easiest start. Another comment says PLA still has the silk, marble, wood, and glow spools PETG does not. PLA printing is that easier start.
r/prusa3d 1q8oppv is a CORE One+ filament detector whose PTFE tube is squeezed by a protrusion. The thread is a loading path. r/prusa3d 19cqtp2 is an MK4 filament-sensor argument. One reply runs 1 kg spools of SUNLU PLA and reports no sensor trouble. SUNLU is that brand.
Pros and cons
Pros
- PLA, PETG, and ASA are checked against the stored printer maxima instead of a forum material list.
- The PETG warping comments stay on the MK4 thread. They are not written into the PETG datasheet.
Cons
- The threads say MK4, MK4/S, Core One, and Core One+. The catalog rows are MK4S and CORE One+ only.
- There is no Prusa Mini in the printer table, so this page has no Mini nozzle or bed maximum to publish.
Printer considerations
- The MK4S product page lists a 290 °C (554 °F) maximum nozzle, a 120 °C (248 °F) maximum heatbed, a Nextruder direct drive, a brass CHT nozzle, and an enclosure that is not included. Hardened nozzle is false on the record.
- The CORE One+ product page lists the same 290 °C (554 °F) and 120 °C (248 °F) maxima, a heated enclosed chamber, a brass CHT nozzle, and MMU3 support. An HT hotend rated to 400 °C (752 °F) is described there as coming soon. The stored maximum stays 290 °C (554 °F).
- Prusament PA11-CF lists 275–295 °C (527–563 °F), so the top of that nozzle is above both printers, and hardened nozzle is true on that filament. The printer records store brass.
What the community says
r/prusa3d 197ialb is MK4 PETG warping. The leading comment says PETG and brims go together, asks for an extra -0.05 of squish on the MK4 textured sheet, and says scrub the sheet with a soap degreaser and then isopropyl. Another comment asks about room temperature and drafts. A third says enclose four sides and leave the top open if a vent is blowing. r/prusa3d 1ilu19b asks why a CORE One absorbs heat for about 7:40 before PETG when an MK4/S does not. The leading comment says an unenclosed MK4 has only the room to heat. Another says the gcode is waiting on a chamber temperature. r/prusa3d 1im3lgv asks whether a CORE One should skip PLA for PETG. A comment says the CORE One can print from PC to ASA to PA and that PLA is the easiest start. r/prusa3d 1q8oppv is a CORE One+ filament-detector path, a PTFE tube squeezed by a protrusion. r/prusa3d 19cqtp2 is MK4 filament-sensor complaints. One reply prints 1 kg spools of SUNLU PLA and reports no sensor trouble.

Questions
Does Prusament PA11-CF fit the stock MK4S or CORE One+ nozzle?
The filament lists 275–295 °C (527–563 °F) and hardened nozzle is true. Both printers store a 290 °C (554 °F) maximum and a brass CHT nozzle, with hardened nozzle false. The top of the PA11-CF nozzle is above 290 °C (554 °F). The carbon-fiber guide is the hardened-nozzle question.
What about the Prusa Mini?
The printer table has the MK4S, the CORE One+, and the XL. It has no Mini row, so this page does not publish a Mini maximum. The MK4S and CORE One+ pages are the stored limits, both 290 °C (554 °F) and 120 °C (248 °F).
