RESOLVED!!!

i submitted a ticket to support and this is their answer.

You only need to adjust the Z-offset parameter of Extruder 0, which corresponds to Toolhead 1. After you calibrate the Z-offset using Toolhead 1 and confirm that the first layer prints well, please run the multi-toolhead offset calibration once again. After completing this calibration, the print quality of the other three toolheads will be aligned with Toolhead 1.

Hi all,

Can I get a guidance regarding the U1 Z offset? (pic attached)

These are my current Z offset settings in the printer.cfg

Is the U1 should have been automatically adjust those Z offset for each extruder before I manually changed them all?

Do I only need to change the z offset of just "extruder"? and not the rest?

TIA

EDIT: I have defaulted and updated to PAXX12-16 firmware. Current Z Offsets : the z offset: -0.05 ; 0 ; 0 ; 0.

I have used this Bottom Feed since I got my U1 last month. My filaments are on cereal dry boxes below the printer table.

This setup works but I have been getting filament jammed/stuck error and loud squeaking noise while printing. Very annoying. Totally killed my excitement for this printer.

I escalated to snapmaker support and to their credit, they sent me a new feeder.

But before I tried the new feeder, I decided to rotated the feeder back as per instruction. For the past week, I use the 1/2 feeder like that and the 3/4 feeder rotated still. I have noticed that I've been "clearing" stuck filament on 3/4 feeder but not 1/2 feeder. Squeaking still ongoing but way less often too. Dryboxes still on the same position.

So. this is my PSA, do not rotate your feeder.
