Engraving creates "Thermal Inertia." As you process a design, the baseline temperature "creeps" up. If you don't manage this, you hit the Heat Wall—where the material can no longer cool down.
Act I: The Bug
The "Heat Creep" Runaway
Elapsed Time
0.0s
Baseline Temp
20°C
Bulk Heat Accumulation
The Failure:Heat Creep is the process; the Heat Wall is the result. Halfway through this 30-second job, the creeping heat pushes the material past its physical limit. The part starts to burn because it can no longer sink the energy.
Act II: The Fix

Thermal Balance
The Success: By managing the Thermal Plateau, we ensure the 100th line looks identical to the 1st. On the xTool F2, this is achieved by using Inter-Pass cooling—either through software pause commands or by splitting high-density jobs into multiple lower-power passes.
