Hi all.

HELP!!

Had my V1 orion printer for approx 6 months now. I switched it on one day and the z axis went a bit haywire and so I thought I'd update the firmware.

Got it all working again except for.....

It now reads 091S when switched on (used to say Repetier 0.91) and the temperatures are set to 229 and 90 for hot end and bed. However the temps max out at 175 and 80.
Changed the Thermistor over twice now. I just cant reach the set temps anymore.

I've also changed the Configuration h file

#define MAXTEMP 290

/** Extreme values to detect defect thermistors. */
#define MIN_DEFECT_TEMPERATURE -10
#define MAX_DEFECT_TEMPERATURE 300

Still no joy. Can anyone help me.

Thanks for your time

Although i cannot give you a very specific response, it could be that the maximum pid and PWM values for the bed and hotend are not set to 255.

Another reason could be the fact that your temperature sensors are set to the wrong type which would make them very hot, but it would only display an incorrect temperature.


How do you define maxing out? Does it not exceed that value? Did you try to redo the PID calibration?

Hi Teoman.
Thanks for your reply.

It seems that I can only reach 190c on hot end where as before it would reach 230c no problem and quite quickly too.
Because I have changed the firmware I'm guessing its the values that have changed and is causing this.

I'm afraid I'm very new to this and I've not touched the PID or PWM settings. I'm not sure what that is

I have even tried to upload the 0.91 firmware but it just keeps reading 091s

Any help would be very much appreciated.

Ok I've discovered what PID is

I'm using Matter Control and I've ran the command

M303 E0 S230

It's got all the way to 175c and is now cooling down again.

Not hitting above 200c

Can you set it to 240?


Also fiddle with the pid settings manually to see if you can get it to rise to 230. You could have a dead heating resistor OR bad pid parameters.
