Troubles regarding tuning heaters

ZeSwede

Hello,

Recently, I decided to buy a Duet Wifi 2. I'm excited to get it up and running!

So far, I've successfully completed all of the wiring. Now, I'm going to the fine tuning of everything. I started tuning my hot end and bed, following the guide "Tuning the heater temperature control", but I'm running into an issue. I should mention that this is the first time I've messed around with G-code for my printer, since with my last setup, I never had to. I was able to run auto-tuning and got results for both heaters.

I went into the G-Code console and typed:

M303 H1 S205 ; AUTO TUNE HEATER 1, DEFAULT PWM, 205C TARGET OR MAXIMUM TEMPERATURE
M303 ; REPORT THE AUTO-TUNE STATUS OR LAST RESULT

The auto-tune finished, so to get the results, I typed:

M307 H1

And got this back:

M307 H1 A361.1 C123.4 D4.2 V12.5 B0

And to "save" it, my understanding was to type "M500" which I get this back:

M500
Warning: No M501 command was executed in config.g

I tried again with H0 which is the heated bed, and I got the same result. Am I doing this correctly? I also just installed a genuine E3D V6, and followed this setup guide https://www.matterhackers.com/articles/how-to-assemble-an-e3d-v6-all-metal-hotend. Towards the end, it says that you should do PID tuning. should I ignore this and only proceed with the "Tuning the heater temperature control" from Duet?

I appriciate any help, Thanks!

This was the link to the PID tuning that the E3D setup referred me to. https://matterhackers.dozuki.com/Guide/PID+Tuning/6

Your heater tuning results have been saved to the config-override.g file, but they won't be used because the command to run config-override.g is missing from config.g. So go into the System Editor in Duet Web Control and edit config.g by putting a M501 command at the end.

This worked out! Thank you very much.
