Printer gets up to temp, but won’t start printing..

Spectrum upgraded my internet service this morning and I had to go through and change all my ip settings. Now I am having a problem starting a print. The printer gets up to temperature, but it never starts printing. Just sits there at temp.

I do not have an LCD on this printer, but the status window repeats this message every 10 seconds or so.....

The progress should be updated Now: M117
O.33% Est 0:09:26

Since I am accessing Marlin through USB serial port, the ip changes shouldn’t matter, Just providing that info as the only thing that’s changed.

Maybe I was not clear (as usual)....

Please look at status window in attached screen shot. I don't know what the M117 gcode is about, but looking up the codes tells me that it has something to do with an LCD. I don't have an LCD on the printer.

Also, I getting the error at the bottom a lot. I think that means that I need to run the PID routine, correct?

it shows you requested 255c on the hot end and it only got to 248c before giving up...

The error message is the issue

Error heating failed. Printer halted.

The printer not do anything after that error.


What it means is for the amount of energy should be going into the hotend heater is not producing the expected temperature.

The causes are numerous.

1) the thermistor has detached from the hot end. even a tiny air gap will cause big issues
2) loss of power, check the hotend is attached to your controller properly. (no lose screw terminals)
3) a cooling fan blowing on the hot end when it shouldn't, not allowing it to get to temperature. (Fans should be on heatsinks or printed parts, not the not end)
4) after checking all the above, retune your hot end pid values.

Thanks for your response.
I checked all the connections and wires for both the thermistor and heater and all was well. This is a brand new E3d extruder and hot end so all the wiring is pretty solid.

The cooling fan only cools the extruder fins and not the hot end

I am running the PID with "M303 S245". Once I set the new PID values, is this persistent or do I have to actually load the PID values into the configuration.h?

The following was returned by the PID autotune procedure.

I have no clue where the "M1M105" is coming from, but I see from the output that this does have to go into the configuration.h

I ran the PID autotune and it returned a new set of values. Below is what I got when I tried to set the new values.

>>> M301 P18.11 I1.86 D44.13t
SENDING:M301 P18.11 I1.86 D44.13
echo: p:18.11 i:1.86 d:44.13
>>> M500
SENDING:M500
Error:EEPROM disabled
[ERROR] Error:EEPROM disabled

Setting hotend temperature to 245.000000 degrees Celsius.
Error:Heating failed, system stopped! Heater_ID: 0
[ERROR] Error:Heating failed, system stopped! Heater_ID: 0

Errorrinter halted. kill() called!
[ERROR] Errorrinter halted. kill() called!

Apparently there is still an issue, but not sure what to think. I checked the power on the p/s and it is 24v as it should be.

your not updating the configuration.h, your attempting to save the setting to eeprom M500 (this would normally be fine)

BUT your configuration.h has the eeprom disabled

If you want the machine to remember this setting you have no option but to edit the configuration.h and compile and upload the new firmware.

or you could add your the M301 gcode to your gcode start file so that it gets run every time
