After heating chamber, when cooling h2d gives heater is abnormally hot

Set he camber to 45 degrees, wait until it reaches that point and set the temp to 0. After a minute or so the printer pops up an error that the chamber heater is abnormally hot. Happened with two different machines. The QR leads to HMS main page.

I am having the same issues since i have updated the firmware. As soon as the chamber hits 60 degrees for abs gf printing it pauses and the red light flashes. Saying chamber temp abnormally high.

To me, after opening a service ticket, they accepted my replacement. Open the ticket and they will ask you if you would like to receive the spare part or return the printer.

hey mate, please help , i pershesed the bambu lab h2d laser combo and after i printed with abs, the machine gave me 8 errors

  • Toolhead not detected
  • Extruder temperature sensor error
  • Heater error / heating failed
  • Hotend fan error
  • Auxiliary part cooling fan error
  • Bed temperature sensor error
  • Chamber temperature sensor error
  • Communication lost with toolhead (MCU error)
    i dont know really what to do the machine is brand new and worked just 4 hours
    i have oppned a ticket with banbu lab 3 days a go and there is no reply till now ,
    honestly guys am stressing out, have a jobs to do , invested 30k to make injection modling parts and the printer is not reliable at all to do my prototypes,

any one can help please

Have you solved the problem? I received the printer as a replacement but the problem persists!

No, but i think the message is a firmware thing. Just tried again and in my case: after turning the chamber temp back to 0 it cools down pretty fast and I get the error and right after that the chamber fan jumps in again causing a temporary temperature raise due to the still hot heating element. After that it lowers but more gradually. That all seems correct and controlled behavior except for the message which is alarming.

Did you ever figure out a fix to this? I recently started printing with PC and would get this error after the print is done. I’ve just been power cycling the printer to get rid of it :frowning:

Try adding a fan to the main controller vents.

Apologies if this has already been adressed elsewhere, but I can’t seem to find a similar sub-category for the H2S firmware updates, but this exists already for the H2D ?
Its important to know when public beta’s are available and what features/bugfixes are coming next!
or am I just missing the link somehow and this sub already exists??

Cheers!
