First Layer Issues

What is the problem?

The first few layers are terrible when printing through Octoprint. Once it gets passed that, it's perfect. When I print the same g-code through the printer directly it looks great. In the photos below, Octoprint is on the left and directly on the printer through sdcard is on the right.

In the attached serial log I let the printer only print the first few layers and paused it to confirm the second print was as bad as the first full print.

What did you already try to solve it?

Reviewed printer profile information. Re-leveled bed

Have you tried running in safe mode?

Safe mode said my firmware had an issue.

Did running in safe mode solve the problem?


Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

Octoprint is the latest version, Printer is QIDI X-Plus II

The homeassistant plugin is making a lot of trouble. You may try with disabling that one.

Never heard that Safe Mode can do that. Safe Mode just deactivates 3rd party plugins.

I'll try disabling the home assistant plugin. If I don't have the CDB Fix Plugin, I get the firmware error popup.

Yes, the Qidi printer needs that plugin.

Can you share the gcode file you used as well?

yup, here ya go

Can you point to links regarding this.
I'd be interested to read & see if I can relate it to any of my few minor issues.
Will happily dump it if it raises suspicions.

This is regarding the octoprint.log.
There are exceptions all over it.

Hi, It looks like you have 'under-extrusion" at the first layers. (Even your good print has less, but still suffers a bit under extrusion.) You did not say which slicer you are using. In Cura there are several first layer settings. Also first few layer settings, like slower first layers. I suspect the issue is something to do with speed of printing, and/or extrusion.
Think of this, you are probably printing with G-code speeds in one mode (either Octoprint or direct mode) and the other, (most likely direct printing mode) your machine reverts to default printing and/or extrusion speed.
Not sure which setting is the cause, but maybe this help point you towards finding the issue.
Good luck.

Great observation, Ted. I’m going to look into that!

does your slicer have the ability to add G- Code at the very least G28 checks bed center but if you add G29; M300 it will do a auto bed level and remember the outcome sending it to octoprint. I Use Simplify3D and had to add it. Pursa auto does it .
