Heater heat up but cannot reach to the temperature (2 to 5 degree below)
So I just install a e3d v6 into my Boxzy printer.
After I update the firmware and PID autotune it, I can still print PLA, but I notice the temperature was 2 degree below the temp I want. So I tried other filament that need a higher temp and the heater wont reach the temp (2 to 5 degree below) and the printer just don't start.
For example, I print PETG at 250 degree but the heater only heat to 245-247 degree so the job will not start.
Now I can only print before preheat to 255 degree and start the job.
Does anyone know where is the problem ?
Thanks

here is my setting
can you measure heaters resistance?
for 40 Watts:
12V Heaters are around 3.6 Ohms
24V Heaters are around 14.4 Ohms
I don't have the equipment to measure but the heater has marked as 12V 30 watts. Ordered from E3D in a full kit
Is this the original firmware or some forked and modified version? If it was modified for 24V on 12V heaters it would explain it.
The dead-time control now is really work and there is no limit to the power, but after few second of starting the print. It stop and got a error like this :
So do you know what is happening ?
Also always start with the good part so we can see how bad part evolves.
From the messages it seems like firmware is not sending all "ok" responses. Maybe related to the error message wanting a value 0-255 but gets always resend the same value. Never seen this error.
