Hello together
I am a “proud” owner of a J1 (which I upgraded with the cooling fan upgrade kit) so its now a J1S I guess.
I’ve been observing a specific behavior on my Snapmaker J1S and would appreciate some help understanding the relationship between Z-offset calibration (during the print), heated bed leveling (under Calibration) and the setting Maschine Settings: Glass thinkness.
I’m trying to solidify my understanding of the correct procedure for changing the glass thinkness on the Snapmaker J1S, and I’ve made a specific observation I’d like to confirm.
My Core Observation:
I have noticed that the printer’s Z-Offset value is only actively updated when I perform the “Heated Bed Leveling Calibration” process after changing to a different thickness. I would expect (maybe its just me) that if I change the glass thickness the Z-offset is adjusted automatically without the need to run calibration procedure.
Thanks, Wombley, for confirming that observation. That aligns perfectly with my understanding, that the setting acts as a calibration endpoint, not a live adjustment (unfortunately).
Building on that, I have a related calibration question: What’s the recommended method for fine-tuning the Z-Offset on the J1 which not include using the Z-offset calibration during the print?
Specifically, I’m trying to establish a reliable base Z-Offset for both the smooth glass side and the textured side of the build plate. I’m currently seeing slight over-extrusion on the first layer when using the glass side, which suggests my offset needs a minor adjustment for that surface.
