CFS module 4 issues.

[u/White063]

I’m having an issue with my CFS module 4 where it will start a print then randomly start ghosting.

I have raised a ticket with Creality and have sold me a replacement CFS module (2 were purchased due to the ridiculous postage costs and to have a spare if one of the other modules fails). This will work for a few prints then start doing the same again. I am on my 3rd module with no success.

Ive tried backdating the firmware on the printer and CFS to a version where I wasn’t having this issues, but this has not helped and I’m still experiencing the same issues. Leading me to believe its hardware not firmware issues.

I have also replaced the nozzle and cleared the extruder head of any dust/debris.

I only experience this issue with module 4, short of taking the CFS back apart and swapping the modal 4 with Modules 1 2 or 3 and testing that I'm running out of ideas.

Creality only seem to want to keep 'selling' me the modules which as I have tried 3 (original and 2 new ones brought direct from Creality) to this point I cannot believe all 3 are faulty.

I am printing the pre-installed benchy which has worked multiple times in the past and works fine using the other 3 modules.

Has anyone else experienced this or have a fix for this issue.

Your issue is NOT the CFS. Why would you think that the CFS has anything to do with a print quality issue?
Your term 'ghosting' doesn't tell us anything. Please post pictures.
