Improving dimensional accuracy on Bambu Lab H2D with PETG HF

H2D - Geometric Accuracy

I tested this with my machine today. Using precision wall+arachne, without hole/contour compensation enabled. My machine has been calibrated with vision encoder. Note that I’m printing in Bambu PLA Basic, but since no compensation is turned on, so no scaling would be applied. 2mm hole: I got 1.85mm 3mm hole: I got 2.88-2.90mm 4mm hole: I got 3.93mm All measured by using a mitutoyo caliper. So does this make sense? I think yes, a Δd=0.1mm ish error is well expected. It’s just how slicer wor…

This is my test result, I don’t think it’s a printer thing at all.
