Yes , they sent a replacement , and it fixed the issue, been working fine for months now.
Triple check your cables , push them in snug but gently , I had a clog sometime back ( my fault) and had to disassemble the hot end, I saw the error come back till I made sure the cables where all in properly, been find for months after that.
Ho anche io questo problema da diversi giorni sto provando a seguire bambuwiki e a vedere se i collegamenti hanno qualcosa che non va ma non ne vengo fuori tutto collegato correttamente…ho aggiornato la mia p1p a p1s e andava tutto perfettamente dopo qualche mese cosi a caso si blocca non stampa e partono tutte le ventole ad andare al 100%. ho aperto un ticket spero sappiano risolvere il mio problema che mi sa si tratta della scheda
This just happened to my new X1C after it’s second print. I installed a new nozzle and checked all the connections there to make sure it was all connected. I’m waiting on my microsd to export my log so I can report this. Should I open the entire toolhead assembly and reseat all the connections?
P1S with about 1000 hrs printing on it.
just stopped mid print. wrote it off as a failed print…restarted and im now getting HMS_0500_0300_0001_0002 error. tried everything in the wiki; no dice.
i’ve opened a support ticket…anything to try in the interim?
i’ve also reseated every cable on the toolhead. removed rear panel and checked all connections there.
printer will power up…AMS lights will blink double red…i’m being prompted to updated firmware (attempts to update will fail)…and the chamber fan just seems to spin at 100%.
im unable to turn that fan off/on…front panel seems to think the fan is off…
any help is appreciated!
What was the solution here? I’ve checked all my cables numerous times and even replaced my tool head cable and tool head boards same issue
unfortunately; the solution was a replacement cable from bambu…after a fair amount of back/forth w/support
For anybody that gets here, i’ve compiled some documents to help you get the quickest support after having to wait 3+ days for any replies from them. I can’t post links so i’ll say what to Google to find them in the wiki.
First, make sure to record videos of each LED and what the status is:
Search Google for “Bambu Lab Printer Indicator LED explanation”
Second, get a log dump to SD card and include that as well.
Third, verify that the USB-C cable is seated properly and provide pictures to them of this as well:
Search Google for “Bambu Lab USB-C Cable Connection Issue”
Fourth, test with new complete hotend and explain to them you did this.
Fifth, report if it’s only the hotend not heating up that is the issue.
Hopefully I won’t have to wait weeks just to get any replacement parts or support, but hopefully this can help anybody else who has this issue to get quicker support by having everything ready for them already.
hello, it seems my issue is exactly the same as yours (except the part where AMS lights blink double red). may i know what cable was replaced - is it the P1 Series Toolhead Cable? and how long does the bambu team usually take to respond?
I am following this the wiki bambulab Circuit Board Power Failure page to troubleshoot & it seems it’s my MC board that has issue
DId this get fixed - I am having a very similar problem.
Same HMS error. Cant update firmware. Cant heat head.
Went through Wiki. Replaced multiple cables and boards
Cant turn on 1 of the fans as well
I am experiencing the same issues. I received all the recommended parts from the help desk and changed everything. Still receiving the same error. Please help, my print has been down for a month and the help desk takes awhile to respond.
I had the same problem with my P1S printer. After going through the Bambulab trouble shooting guides on line, it was due to inproper cable connection in the toolhead after cleaning the extruder. Make sure that all the pin connectors in the tool head are pinned properly. The top right corner by following the link-
The pins have to be plugged carefully into the right position. You feel that it is pinned right, but even a small mis-alignment will plug in improperly. I fixed the problem by carefully plugging the connectors.
