When you use M500 to save computed values, they go into config-override.g. M501 loads the config-override.g file. So add M501 to the end of config.g so that it gets loaded at startup.
-
@Phaedrux Cool beans, I had to run it again as the 501 would not be in place until rebooting takes place it failed. But ill run it again. Ambient room temperature is at 35*C now so it will affect the calibration I dont know if i should change anything.
-
@Phaedrux It keeps failing
-
It succeeded once though didn't it? If you use m500 after it completed successfully once the values would be saved to config-override.g. do you see anything in that file?
-
@Phaedrux I didn't have m501 in my config file. I sent m500 after I put it in but would not work because the printer said that m501 was not in the config file. So I had to reboot it. And now I can't get it to work.
-
Are you allowing the bed to cool right down to room temperature before you start the tuning process? That is essential.
-
@dc42 indeed.

@Gost101 M500 saves the results of an autotune (and some other info) to config_override.g in the 'sys' folder on your SD card. An example of config_override.g:

either open config_override.g, copy the
M307 H0 ...line to your config.g, making sure you paste it in after, or in place of, any existing M307 H0 command,or add M501 to the end of your config.g, which causes it to run config_override.g after config.g.
M500 and M501 are well-documented in the gcode dictionary: https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M500_Store_parameters

@droftarts Thanks. Also the printer just finished the M303 with another cancelled:

@droftarts Is there a way to ignore the safety's and allow the bed to heat up to 70*C?
-
@Gost101 It's going to be very difficult to tune the bed to the maximum temperature it can achieve, because sometimes it gets there, and sometimes it doesn't. There isn't anyway to disable the heater warning, because that would be unsafe. Try tuning to 60C.
Also, have you changed the thermistor setting in config.g to what they actually are? I've just checked the Creality CR10 S5 Marlin firmware source code. Your bed thermistor should be a 100k EPCOS, and so is your hotend as standard. For the hot end, you linked an E3D heater cartridge, not the thermistor! Are you still using the stock thermistor? If so, it's also a 100k EPCOS thermistor. If they are both standard, change these lines in config.g for (slightly) more accurate temperatures:
M308 S0 P"bedtemp" Y"thermistor" T100000 B4092 ; configure sensor 0 as thermistor on pin bedtemp ... M308 S1 P"e0temp" Y"thermistor" T100000 B4092 ; configure sensor 1 as thermistor on pin e0tempIf you've changed the hot end thermistor, post what it is. Perhaps also post your current config.g.
Ian

I'm using this e3D thermistor for the hotend and the stock one for the bed. Granted I need to buy a higher temp one for the hotend. link text
-
@Gost101 Okay, so that's a Semitec 104NT (a drop-in replacement for the discontinued Semitec 104GT). Change config.g to:
M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 1 as thermistor on pin e0tempIan

@droftarts Tunning for the bed failed again.

@droftarts Is there a way to increase the time before the heater faults for rising to slowly?

@droftarts Is there a way to increase the time before the heater faults for rising to slowly?
From the docs:
If auto tuning fails with a message that the temperature is not rising fast enough, this indicates that either you are using too low a P value in the M303 command, or the dead time in the existing model is much too low for your heater. You can increase the dead time using the M307 command. For example, sending M307 H0 D30 will increase the dead time to 30 seconds. The actual dead time will be known after a successful auto tuning.

Hi,
Going from the docs I think you want to remove the G29 and add a G28.
On my printer, instead of using homing, I just set the Z=0 datum using G1 to move to the center of the bed and G30 to probe.

@fcwilt tried what you said didn't do what it was supposed to do. I think there is a lot more code that is involved in this.
