Troubleshooting 3D Prints on Anycubic Printers
Anycubic's Kobra line is one of the best-selling budget bedslinger families on the market, and until recently every model in it was open-frame. The Kobra S1 changes that with Anycubic's first enclosed, auxiliary-fan-equipped machine.
The Anycubic lineup we cover
9 curated Anycubic machines are in our knowledge base, taken from the vendor's own OrcaSlicer-family printer profiles: 1 of 9 ship (or come standard) with an enclosure, and 1 of 9 carry a dedicated auxiliary (side/chamber) part-cooling fan in addition to the main print-cooling fan.
| Machine | Enclosed | Aux fan |
|---|---|---|
| Anycubic Kobra | No | No |
| Anycubic Kobra 2 | No | No |
| Anycubic Kobra 2 Neo | No | No |
| Anycubic Kobra 2 Pro | No | No |
| Anycubic Kobra 2 Max | No | No |
| Anycubic Kobra 3 | No | No |
| Anycubic Kobra 3 Max | No | No |
| Anycubic Kobra S1 | Yes | Yes |
| Anycubic Vyper | No | No |
Kobra, Kobra 2, Kobra 2 Neo/Pro/Max, Kobra 3, Kobra 3 Max and Vyper are all open bedslingers with no enclosure and no auxiliary fan. The Kobra S1 is the exception: fully enclosed with an auxiliary fan, aimed at the same enthusiasts who'd otherwise buy a tent for their Kobra 2.
Cooling and the enclosure question
Across almost the entire lineup, cooling means the part fan and nothing else — there's no chamber to trap or vent heat, so PLA and PETG behave close to their stock profile predictions and ABS/ASA printing means owner-built enclosure or accepting the warping risk. The Kobra S1 is the one machine in the family where chamber heat actively helps: expect it to hold ABS/ASA corners down noticeably better than any open Kobra, with the auxiliary fan doing the local cooling job the enclosure's stiller air would otherwise cost you.
Baseline settings for Anycubic filament profiles
These are the values the vendor's own OrcaSlicer-family profiles ship with for the materials it supports natively; use them as your starting point, then adjust per spool with the calibrations linked below.
| Material | Nozzle | Bed (textured) | Fan max |
|---|---|---|---|
| PLA | 220 °C | 45 °C | 100 % |
| PETG | 255 °C | 80 °C | 90 % |
| ABS | 260 °C | 105 °C | 80 % |
| TPU | 240 °C | 35 °C | 100 % |
What tends to go wrong on Anycubic printers
Warping on any open Kobra running ABS or ASA. No enclosure means bed temperature, minimal part cooling and a brim carry the whole job. See the ABS/ASA warping guide.
Bed adhesion inconsistency on the flexible steel plates. Budget flexible PEI sheets scratch and lose grip faster than premium ones; a plate that used to hold PLA fine but now releases mid-print is usually worn, not mis-tuned. Wash with soap and warm water first — see the bed adhesion guide.
Stringing on PETG. The most common support request across every budget bedslinger brand. Dry the spool, drop temperature 10 °C, then retraction — in that order. Full walkthrough: PETG stringing.
Before you assume it's a setting
None of the numbers above are Anycubic-specific magic — they're the vendor's own OrcaSlicer-family profile defaults, which means they carry the same caveat every third-party filament profile does: they're a starting point, not a guarantee. Two checks catch most "the settings are wrong" reports before they turn into hours of random tweaking:
- Run flow-ratio calibration on any filament that isn't the exact brand the profile was written for. A generic or off-brand spool can be several percent off the stock flow ratio, and that shows up as over- or under-extrusion that looks like a slicer problem but isn't.
- Confirm the plate type in the slicer matches the plate on the bed. Mismatched plate selection is the single most common cause of a print that "should have stuck" on any of these machines, Anycubic included.
Whatever you're chasing beyond that, the general fix is the same everywhere: change one variable, print a small test, read the result before touching the next value. The diagnosis tool turns your specific machine, filament and symptom into that ordered list automatically.
Frequently asked questions
Why doesn't PLA stick to my Anycubic Kobra's build plate anymore?
Usually the flexible PEI plate is worn or greasy, not mis-tuned. Budget flexible steel plates scratch and lose grip faster than premium ones, so a plate that used to hold PLA fine but now releases mid-print is typically worn. Wash it with dish soap and warm water first, and confirm the plate type selected in the slicer matches the plate actually on the bed.
What temperatures do Anycubic's stock filament profiles use?
Anycubic's own OrcaSlicer-family profiles ship with: PLA at 220 °C nozzle and 45 °C textured bed with 100 % fan, PETG at 255 °C and 80 °C with 90 % fan, ABS at 260 °C and 105 °C with 80 % fan, and TPU at 240 °C and 35 °C with 100 % fan. Treat these as starting points and run flow-ratio calibration on any spool that isn't the exact brand the profile was written for.
Can I print ABS or ASA on an open Anycubic Kobra without an enclosure?
Only with a workaround. Of the 9 Anycubic machines covered, only the Kobra S1 is enclosed with an auxiliary fan; every other Kobra and the Vyper are open printers where ABS/ASA means warping risk. On those, bed temperature, minimal part cooling and a brim carry the whole job — or you build your own enclosure. The Kobra S1's chamber heat holds ABS/ASA corners down noticeably better.
