I was printing correctly and suddenly it has started to paint and it has marked this error:
Error:Heating failed, system stopped! Heater_ID: bed
[ERROR] Error:Heating failed, system stopped! Heater_ID: bed
Error:Printer halted. kill() called!
[ERROR] Error:Printer halted. kill() called!
[ERROR] Can't read from printer (disconnected?) (SerialException): call to ClearCommError failed
[ERROR] Can't write to printer (disconnected?) (SerialException): WriteFile failed (WindowsError(5, 'Acceso denegado.'))
Could you help me to check what can go wrong?
In the end that was not the problem. I thought I had fixed it but it was one of the power supplies that was failing. I put them inverted and the hot bed worked but the printer did not receive enough power (so the base fan did not make noise) Now I have to get a new power supply with the same characteristics. The blue led of the power supply that fails flashes constantly, it is rare that it fails if it is practically new ... Do you recommend any model?
fixed and curiously not because the base fan makes less noise :S
Double check that the thermistor connection for the headed bed hasn't come undone from the mainboard. I had this problem when moving the printer around.
When doing the heater bed test, the red led turns on but now the temperature does not rise, everything was correct until it stopped working.
