This isn’t a flow issue. That huge gap on the right side is positioning, not flow. The gap extends deep in to the print and it’s much wider than just one extrusion width. It’s not belts, or the errors in extrusion would be more random. This looks like the printhead went exactly where it was told to go, but where it was told to go was wrong. Why only in only a few very specific areas? No idea.
Experiment - rotate the model 90º on the build plate so the “D” orientation is changed and run the print again. If the model won’t fit rotated 90º, rotate it 180º instead.
Additional thought. Is the D closest to the Aux fan (does a H2D have an Aux fan?). If it is, this problem might be cooling related. Turn that fan off.
The result changed, but it’s still clearly not right. That big gap that isn’t present in the slicer is still present in the printed part. If it was a mechanical issue, rotation should have changed it. There’s got to be something wrong with the G-code. Weird the slicer doesn’t show it, though. Might be some kind of timing dependency in the motion control firmware. That’d be my guess, code bug but not in the slicer, it’s in the printer FW.
Ah, makes sense. Sure the slicer and the G code should be hand-in-hand, so yeah, maybe it is a FW thing. I really appreciate all your suggestions and help. I love these forums! I guess at this point it’s up to Bambu to address my ticket. Of course it’s gonna take a lot more convincing of them than it took of this group
Could be just a flow dynamics issue, try do it from Bambu Studio in the Calibration page, see your automatic calibration result and manual calibration result, see if they match close enough (~10% difference should be ok, e.g., 0.030 vs 0.033 is fine)
It would get fixed when you disable “Detect narrow internal solid infill”.
I feel like the gap infill isn’t properly applied in this version. @SupportAssistant thanks for your previous quick response, can we get a fix on this as well?
