What is VFA?
“The text must contain at least 20 characters, end quote”
Vertical fine artefacts. Typically caused by motors or belts.
Same issue. Here’s my fix. New printer, latest firmware. I printed the included Benchy, twice.
I noticed the video on my SD card ended at exactly the layer shift layer so I figured there was some issue in writing to the card that was messing the controller up. I left the card out, video was off and it worked. Haven’t dome any more testing beyond that. My card is a Sandisk Ultra 32GB, formatted in the printer. Glad to see it might be a firmware issue.

Try recalibrating and then print a benchy you sliced after the update, that’s what I did.
Got my X1c today and when I started it up it said there was a firmware update so of course I clicked ok. Well 2 benchys later, shifting layers in the same spot, cleaning, re-tensioning the belts and lubing the z screws I came across this post. I rolled back to 1.05.02, tried another benchy at ludicrous speed and it had no issues.

Hello everyone,
i am having a problem with the print:
I am printing a rig to insert an aluminum profile 30x30x240mm where i want to print on top.
due to the nature of my .stl bambulab gives me a warning that it might be unprintable (part of it is floating in midair.)
I am inserting the following code in the first layer after insertion, so that i can enter the profile:
G1 Z100.0 ; move print plate down for user intervention
M400 U1 ; pause for user intervention
M104 S290 ; hot end temperature to 290C
G28 X Y ;Home in X and Y
However after the printhead resumes print, it seems it freaks out due to detecting my profile and does a random movement. It is random as in every of the three tries, the movement was different.
Do i have to deactivate the lidar or something else?
I am a bit clueless on how to proceed.
Any help is appreciated!
Did you ever figure this out? Mine has just started doing this as well
My printer has also started doing this. On a model that I’ve probably printed over 20 of perfectly. Any further tips? It’s mid failing a print right now so I can’t check the firmware version but I’ll definitely roll it back if I can. I’m not very prompt with the firmware updates so I might not be in luck to find that it’s indeed a new firmware issue.
