PID Tuning Procedure

@droftarts ,
Thank you for the help. Please forgive my ignorance. As I look over the document you refered me to"Result
If successful, the firmware will report the parameters to use, and an M307 GCcode command e.g.:
M307 H1 R7.046 K1.519:0.006 D3.58 E1.35 S1.00 B0 V23.9 (RRF 3.4 and later)
M307 H1 B0 R1.839 C270.7:170.1 D8.10 S1.00 V12.1 (RRF 3.3 and earlier)Then, either:
Copy this into your config.g, replacing the existing one for the heater, or
If your config.g has M501 at the end, you can save the current heater settings by sending M500. This will save the current parameters to the sys/config-override.g on the SD card. M501 in config.g will load them at each reboot."I do not see a line of code in my config.g that looks like this to copy the info to? see config.g below. Do I need to create it? If so where?
I also do not have a M501 in my config.g? again same as above, do I add it? where?Config.g

Do I just copy and past the code
into a new Macro in the User interface?No, that would be a bad idea as the PID tuning parameters (in the first macro) depend a lot on your printer.
I offered up the macro as a way of assisting in understanding some of the parameters, assuming you may have been familiar with running macros.Can you descibe your machine ? From the config file it looks to have two different hotend heaters (H1 and H2) and a bed heater (H0) ? If so, how do you switch between the two different hotends?
Also - it looks like you may be running old versions of the firmware and DWC - can you comfirm by posting the output of M122

This is a custom Machine. It used to be a Folger Tech FT-5 large volume printer 300mm X 300mm X 300mm. The only thing original now is a few stepper motors and the frame. We are running the Duet E3D mother board and E3D Titan Aqua extruder. There is a 110Vac heated bed controlled by the use of an SSR. This also has a custom built enclosure and heaters controlled by an externally mounted din rail Watlow controller. Early on I tried to use the Duet to control the chamber heaters but I ran out of time. I may come back to this.
There should only be two heaters. The hot end and the heated bed. If there are more, then this might be a hold over from the chamber heating attempt.
I am sure I have not upgraded the firmware since the original install so I am sure it is old.
I had never seen a 3D Printer when I was tasked too build this one, and now have a few Enders at home to learn on. I could use some help making this printer what I know it can be.
I will get you the M122 next.

Firmware Version: 2.05.1 (2020-02-09b1)
WiFi Server Version: 1.21
Web Interface Version: 1.22.6Your firmware versions are very out of date. Most of the code suggestions you will get here likely won't work as expected.
I suggest you update your firmware. You'll need to generate a fresh config set for RRF3. https://configtool.reprapfirmware.org/
If you still have access to DWC. Upload these zip files, one at a time in the system tab. Don't extract them first. Reboot after each. Use M115 in the gcode console to verify the firmware has been applied.

@CarlBosson If you don't want to update the firmware, you can still tune the heaters. You just can't tune them as a tool. Use
M303 H1 S200instead.Ian

Thank you for all your help. Sorry for the late response, I have been out sick. Things are a little busy now and I have playing catch up, I may have to take this machine home to work on it. I am sure I will have questions as I go. Thanks and have a great day.

@Phaedrux I have updated to firmware Ver 3.3.
But the kink you sent to Ver 3.4.6 says file not found? -

@Phaedrux Ok I have that done.
I need to be honest. I am in way over my head! Thank you for all the help.
Yesterday I connected to my home network and had access to the DWC but now it will not connect to the same IP address. When I enter M587 via YAT I get the following message?

Try sending these commands to reflash the wifi module as it sounds like it may have failed on 3.3 which has happened before. Make sure you have the wifiserver bin file in the new firmwares folder.

@Phaedrux I am sorry, I did not see that you posted yesterday. I will work on this this afternoon and supply feedback.
I also completed the RepRap firrmwareconfigtool you suggested and have it saved but not yet installed. do I upload that into the system folder the same way as the firmware updates?

Yes at the end of the config tool process you can download your config files as a zip file. Upload that zip file to the system tab in DWC to install them. Backup your SD card first if you want to preserve your existing configuration files.
