My Klipper-ized Sovol SV06+ is having an issue where it reaches about 4 inches on the Z axis and it goes bad. Some examples are below.

Is the print stopping or does the printer keep going like all is well?
If the printer is continuing like everything is normal, you can surmise that the issue is either the heater, the extruder, or the filament path.
What does your temp graph look like during the print? Oscillations = potential wiring issue, especially if they’re not present for the whole print.
Have you caught the printer doing this? Is the extruder clicking? If yes, something is preventing the filament from moving through the extruder. You’re either developing a clog or something is preventing the filament from feeding (binding, etc).
If the extruder isn’t clicking, and the print continues for a bit, does the extruder slowly chew through the filament? If yes, you probably need more tension on the feed screw. I would still suggest looking for souces of binding.
