Troubleshooting 3D Prints on TwoTrees Printers

TwoTrees' SK1 is a budget open-frame CoreXY — CoreXY speed at bedslinger pricing, with the trade-off that TwoTrees ships filament profiles for only PLA and TPU; anything else needs a close-match profile and manual calibration.

The TwoTrees lineup we cover

1 curated TwoTrees machines are in our knowledge base, taken from the vendor's own OrcaSlicer-family printer profiles: 0 of 1 ship (or come standard) with an enclosure, and 0 of 1 carry a dedicated auxiliary (side/chamber) part-cooling fan in addition to the main print-cooling fan.

SK1 is an open-frame CoreXY with no enclosure and no auxiliary fan — "a basic open frame CoreXY," per independent hands-on review, with the enclosure sold as a separate accessory rather than included.

Cooling and the enclosure question

With the SK1 open-frame and cooling handled by a single part fan, its thermal behaviour is close to any open bedslinger despite the faster CoreXY motion system: PLA and TPU (the two materials TwoTrees actually publishes profiles for) print close to their stock numbers, but ABS/ASA/PETG have no vendor-published baseline at all here — use a similar open-frame vendor's profile (Creality or Sovol's PLA/PETG/ABS numbers are a reasonable starting point at this price point) and expect to calibrate flow and retraction from scratch. For ABS and ASA specifically, warping control really wants an enclosure — plan on the add-on enclosure accessory (or a DIY tent) before committing to large ABS parts on this machine.

Baseline settings for TwoTrees 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.

What tends to go wrong on TwoTrees printers

Before you assume it's a setting

None of the numbers above are TwoTrees-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, TwoTrees 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.
