E3d Volcano Heating Issues

Hello everyone!

I have been having trouble with my hotends on my mendel90 not getting to 230+. I have ran the PID autotune several times via M303S245C10. It has no problem completing the autotune at that temp. but when I go to print at 235-245 (for PETG) my temps. rise to 200 no problem then the speed tapers off fast until it causes a kill printer error. ( I have increased the time in Config_adv.h) I have had this issue with these hotends: E3d V6 (clone), E3d V6 lite, and E3d V6 Volcano.

It is likely user error but anything will help. Thanks!

Running auto tune and applying the new settings are two separate things. After the auto tune finishes it will output the values for the Kp Ki and Kd. The next step is to apply these changes in the firmware. You can manually do it by opening the marlin file, changing the numbers, and then sending the code to the printer. Or if you have eeprom enabled you can run auto tune and then enter g500 to save the new settings. The line you entered for the auto tune does not look the same as what is on the wiki however. You are missing the E# or the extruder number in between the M303 and the S245. I think the default is E0, the first extruder, which might cause a mismatch between the hot end you auto tune and the hot end you are trying to print with. Different set ups with different hot ends will result in different PID settings.
