our ams on our x1c (less than 1 year old) blocks every 10th print the spool while feeding filament for cleaning the nozzle before starting to print.
What happens is, the spool get pulled up into the top cover and if you let the ams do the print will fail, due to the lack of filament.
Sadly this makes totally no sense, as the rollers does not turn at all at that time when the ams pulls the filament towards the buffer and the next feeder as well as the hot-end.
Where does this fail come from?
False ams control?
Why does the system sometimes block the spool and sometimes everything works fine? Settings? Mechanical issue?
Why at all braking the spool rollers when the ams should feed towards the hot-end?
Some programmed funtions makes totally no sense to me …
keep writing and reminding them several times every day, if possible, as it appears these guys have the shortest memory span on Earth…as from the many posts on this topic alone, I doubt they remember what they’ve answered 30 seconds prior to the same customer for the same problem…
Who you’re talking to?
If it’s Bambu’s staff you’re hoping to reach, this is not the place. They’re rarely showing up on the forum, and even more rarely (read “never”) they react or do something (if anything at all).
If it’s the users’ community you’re asking for help, some might have been confronted with similar situations and could share their experience and how and if they’ve solved their problem. Do keep in mind that what worked out for them might not work out for you.
It’s not possible to fix. It’s a design issue. They need to fix it mechanically (release the news version of this mechanism) or update a firmware. it’s easy to fix with firmware. They need just to add a tiny spin to opposite direction before feeding. This will unlock the ratchet mechanism on the roller. It’s a nightmare to print with supports when the filament is close to the end. The spool gets stuck every second layer!!
