Topic: Temperature Settings
I set the Sestos teperature setting to 180c
Confirmed the Sestos matches the factory settings
Temperature only reaches 145.3c then the Sestos starts flashing orAL
Re: Temperature Settings
After a couple of Google searches, it appears this is a problem with the thermistor I will check my wiring and reroute the thermistor wire outside of the thermal insulation around the nozzle and extruder tube.
Re: Temperature Settings
I am newbie too, just finished setting up my Filastruder.
orAL, not sure if this indicates Over Load Alarm?
What might be the current reading on Stall Protection Board just before that orAL occurs?
Mine was running about 1.2A the most while doing extrusion at 180 degree.
Have you set that setting to 1.5A-1.7A according to procedure? In your message you did not mention that your motor was running, so by the time your motor moves, it will kick your running current even higher. But I think you have to over come your problem to reach 180 degree before running the motor.

Re: Temperature Settings
My guess would be that it means open relay alarm. It is not seeing the system get up to temp in an expected time so it is assuming the relay controlling the heater is defective in some way.
Printing since 2009 and still love it!

I did have the motor running, I will check my settings on the Stall Protection Board
Re: Temperature Settings
I just realized the Stall Protection Board is not running until running the motor. No power is applied to the Stall Protection board until flipping the switch for motor power on.
Like in my case now, I won't turn on my motor until the temperature reaches 180 degree, since I do have cold plastic left inside the nozzle which will block the auger turning free.
I would suggest just have the main switch on, and see if you can reach 180 degree.
The next thing to check is make sure the auger can turn free without the socket, it might be too late now to disassemble in order to check that.

You are correct about the Stall protection. I get the same error with the motor on or off, I checked the auger, it spins freely.
I checked the thermistor wiring and rerouted it outsider the insulation, still getting the same error message orAL
Re: Temperature Settings
Double check your wiring for PID, ThermoCoupler, and heater, if everything okay then sounds the problem is in PID.
But wait for Tim's comment, we do not know exactly what orAL really means.
On my unit, just running the Main power alone, without turning on the motor, my heater can reach 180 degree.
Re: Temperature Settings
I changed the polarity on the thermistor, appears that was my problem.

Just to be clear, what you have is a thermocouple. They do have polarity. However a thermistor does not. It is simply a resistor that has no polarity like all resistors and it's resistance changes with temperature.
A thermocouple generates a very small voltage based on the temp it is being subjected to. That voltage does have a polarity and will swing negative if temps get low enough.

Re: Temperature Settings
good to hear that you found the problem.

You are correct, thanks for the clarification, I got my terminology confused.
Thanks to everyone that read my post and provided support, it is greatly appreciated.
Re: Temperature Settings
orAL is an error code indicating a problem reading the thermocouple.
Glad you got it sorted out!
