This looks great! But I do not know how to use it. I am a little over my head but trying to leaarn.Carl

I tried the M300 T0 S200 command but nothing happened. See what was returned below.M303 T0 S200

No heater has been tuned yet -

Do I just copy and past the code
into a new Macro in the User interface? -

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Web Interface Version: 1.22.6Your firmware versions are very out of date.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 S200
instead.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.

Thank you for your input and the option that you offer. I think I will try to fix it once and for all. "I know that is a fantasy".

@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?
Carl

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.

I have connected via YAT and USB. Keyed in M552 S0 and get the following:M552 S1
Turn off the current WiFi mode before selecting a new one
okI backed up the SD Card yesterday in preparation.
