RE: MK3.5 -Failed Hotend temperature test/
Hi everyone, sadly, I have to report the same issue with the topic starter Mk3 upgraded to 3.5. During the heater self-test, it awaits cooling to 35C and starts heating, expecting the normal heater to get to 290C in 1 minute. I even used a gas torch, but then the temperature overshoots, and at 300C, the firmware restarts the printer. Is that a bug of 6.0.4, or am I doing something wrong?

Thanks, lying about the nozzle type got me past the hot end check. Hopefully Prusa will fis the firmware to allow me to specify a stock hot end without the sock,
Hello,
i've use the same solution for past the hotend check with the latest firmaware 6.1.2 (08/23/2024).
RE: MK3.5 -Failed Hotend temperature test/
Experienced the same error. Annoyingly in firmware `6.1.3+7898` it doesn't even tell you why self test failed, it just asks if you want to edit or retry. Why would they show a generic error screen and not tell you why it was failing? I had to run the test many times and sit there and stare at it the entire time to see that it was failing on the hotend test. I then wasted a ton of time on getting it out of my enclosure, and cutting zip ties and inspecting every wire connection yet again. Checking tension on all the hotend heating connections, etc.
I have a Dragon hotend, I had tried with the sock on and setting it to have the sock vs no sock and no change...but then I removed the sock, but set the printer that it had a sock and it worked. 🙄
So, Dragon hotend:
- Remove sock (if you have one)
- Set printer to "with sock"
Now off to determine why my printer that worked perfectly for years won't actually get close enough to the bed to have a functional first layer.
