Description

When using OrcaSlicer with KX-Bridge, the printer's auto-leveling sequence forces the Cold Plate bed temperature to 35°C, even though the slicer's first-layer bed temperature is set to 30°C and the G-code correctly outputs G9111 bedTemp=30.

This override does not happen when sending prints via Anycubic Slicer Next (where it correctly stays at 30°C during leveling). This suggests KX-Bridge may be incorrectly parsing the temperature metadata to start the print, causing it to send a fallback of 35°C instead of the requested 30°C.

Steps to Reproduce

  1. In OrcaSlicer, set the first-layer bed temperature to 30°C for the Cold Plate.
  2. Slice a model and verify the start G-code outputs G9111 bedTemp=30.
  3. Send the print job to the printer via KX-Bridge.
  4. Observe the bed temperature on the printer display during the auto-leveling phase.

Expected Behavior

The printer should heat to and maintain exactly 30°C during the leveling sequence, matching the G-code and replicating the behavior of Anycubic Slicer Next.

Actual Behavior

The bed temperature is overridden to 35°C during the auto-leveling phase.
After the auto-leveling phase is done, the bed temperature is adjusted down to 30°C.

Environment

  • KX-Bridge Version: v0.9.27
  • OrcaSlicer Version: OrcaSlicer-KX v2.4.1-kx1
  • Moonraker/Klipper Version: N/A (Anycubic Native Firmware)
  • Operating System: Linux
  • Installation: Binary

Thanks for the detailed report and logs, @Blaim.

I traced this through KX-Bridge's code (gcode upload path, MQTT print/start payload builder) and confirmed the bridge never touches bed temperature at all — it uploads the gcode file as sliced and doesn't parse or rewrite any temperature values. So this isn't a bridge bug.

The actual cause is in the OrcaSlicer-KX Kobra X machine profile: the machine_start_gcode uses G9111 bedTemp=[first_layer_bed_temperature] ..., a fused Anycubic macro that heats the bed and does auto-leveling in one step. OrcaSlicer resolves [first_layer_bed_temperature] using its bed_temperature_formula setting, which defaults to "highest temp across all filaments in the project" rather than the temp of the filament actually being printed — and the Kobra X profile never overrides this default. The later M140 command in the gcode body uses the correct per-filament value, which is why the bed corrects down after leveling finishes.

I opened OrcaSlicer-KX#4 with the full root cause and a concrete one-line profile fix. Following up there — closing this one as "not a KX-Bridge issue" once the profile fix lands, but leaving it open for now for visibility/cross-reference.

Root cause identified and fixed in OrcaSlicer-KX v2.4.2-kx1 — this is not a KX-Bridge bug.

The issue is in the Kobra X machine profile in OrcaSlicer. The machine_start_gcode uses G9111 bedTemp=[first_layer_bed_temperature], but [first_layer_bed_temperature] was resolving to the highest bed temperature across all filaments in the project (the default by_highest_temp formula), not the temperature of the filament actually being printed.

The fix: added "bed_temperature_formula": "by_first_filament" to the Anycubic Kobra X machine profile. This makes [first_layer_bed_temperature] resolve to the active filament’s bed temperature, so G9111 and the subsequent M140 command now agree.
