Z-Offset Cura x Labists ET4

[matll42 0]

Hi everyone,

 

I'm new to the community, I just bought a used 3D printer to try it.

 

I'm facing a double difficulty with z-offset and a builder that doesn't exist anymore (Labists).

Each time I start to print, the nozzle go to touch the bed, go up, then go slowly down to bed, then go way up and when going finally to print it's too high to print (2-3 mm).

 

I try Auto levelling and Manual levelling, it seems that I have less offset with manual levelling than with auto levelling.

 

When I send a G28 Z0 command, it goes to the right place.

 

I tried the z-offset Setting plugin for Cura, but as I have a bigger offset than Initial Layer Height, I have to maximize the Initial Layer Height so I can put -1.7mm or more. and that doesn't even fix my issue.

 

I "successfully" printed a XYZ Cube by pausing and adjusting manually twice the Z during the print, so the printer works good and quality is nice, but I mess the bottom surface.

It's been a whole week trying to make it work and trying many things, I'm worrying that I just waste money for a printer that seems to be nicely built.

 

I tried to upgrade to Anet 3.0.0 but it failed ^^. Did someone still have this one and or tried to upgrade to marlin or klipper?

 

Material: Labists ET4 - firmware 1.6.0 (found here) - filament eSun PLA+

Software: Cura 5.7.2 (Anet ET4 settings)

Connected through USB on MacOS

Model: ZYX Cube gcode attached

Sounds like a hardware issue.
This is the UltiMaker community, not the best place to look for help for this sort of thing. 
You will likely find better help in general 3d printing communities or one focused on the brand of your printer.

A quick search on Reddit turned up this discussion.  I don't know if it is relevant.

Hi, no solution was found with the initial firmware, my solution was to flash the Marlin firmware for Anet ET4.

I followed these instructions

With that I was able to manage my Z-offset (but I lost the Cura link by USB)
