PID Tuning Procedure

oliof

@CarlBosson have you tried putting the DuetWifiServer.bin file in to the right directory? It looks like the module reacts and you have a way to submit the right commands.

A PanelDue will allow you to use the machine, but you will lose a lot of convenience compared to using DuetWebControl the least being able to upload files for printing and remote control.

CarlBosson

@oliof Ok well I will listen to advice :). I do very much like the DWC setup. are you saying it's either panel due , or DWC? They can not be used together? meaning can I heat up the printer and up load .gcode files at my PC, then walk over to the printer and use the panel due to move axis and run macros?

The only problem I have with the DWC is this frustrating wi-fi connection. It is due to my ignorance for sure. If I could get this setup to connect reliably to my work and home network I would be a happy guy!

@CarlBosson they can be used together. The PanelDue gives you an interface directly connected to the machine but its more limited that DWC

Here is what I get.

M997 S1
Error: M997: File 0:/firmware/DuetWiFiServer.bin not found
ok

Phaedrux

And you're sure the file is present in the folder?
Is it also present in the sys folder?
Is DWC also updated to 3.3?

It wouldn't hurt to re-download the 3.3 zip file and upload it via DWC again and have it attempt to reflash and update everything. Don't extract it first.

@Phaedrux
My biggest problem right now is that without Wi-Fi access I have no access to the DWC. It is getting late tonight. i will look at all this again in the morning. Sorry to be a bother. Thank you for the help.

I backed up the SD card from the control board on 3/2/24 and these are the directories that were on it:

GCodes
macros
sys
www
DuetDriverFiles.zip

Yesterday when you asked me to "Place this file in the firmware folder on the SD card and send M997 S1 again." I did not see a "firmware folder" so I placed the file on the SD card with these other directories. When that failed, I looked a little deeper and found some firmware files in the SYS directory. So the second time I placed this file in the sys directory. This still failed.
See below a screen shot of the directories on the SD Card, and a screen shot of the files and directories in the SYS directory.

Create a folder named firmware and put the file there. Then send M997 S1 again.

droftarts

@CarlBosson or send

M997 S1 P"0:/sys/DuetWiFiServer.bin"

When you can access DWC, the next time you upload a firmware update, RRF will create the firmware folder and put any further firmware updates in that.

See https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#file-locations-on-the-duet-sd-card

@droftarts
But now that we are this far I still cannot access the DWC.
When I open the browser and enter the IP address the screen comes up blank?

Carl

Phaedrux

Download this file and extract it to the WWW folder on the SD card and try again.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/DuetWebControl-SD.zip

CarlBosson

@Phaedrux
THAT WORKED!!!!! I have the DWC back!!!
I know this is the weekend. Thank you so much for the help. Now I will continue with your other instructions.

Phaedrux

Now that you have DWC, you should upload the 3.3 release zip file once more to make sure everything is where it should be, and then update to 3.4.6 by uploading it's zip file. That would be the normal means of update going forward.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip

https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.6/Duet2and3Firmware-3.4.6.zip

Then you're all up to date.

CarlBosson

@Phaedrux
Again, Thank you so much for your time.
I have updated firmware to 3.4.6, and installed the RepRap config.
The printer is doing some funny things that I am sure are settings in the RepRap config we can work on fixing. But we have solid repeatable connection to the DWC!

I originally started this string to PID tune the heated circuits but now after all your help I need get everything working properly. Then we can fine tune. Please see the Config.g file below. First issue is I cannot home the axes. Is there anything else you can see right away that needs to be fixed? Have a great day! You have made my weekend!

This is a good place to start.

CarlBosson

@Phaedrux
After all your help I wanted to give you an update. I have been using the commissioning document to fine tune the board. As I now have this "Work" printer at my home I have been doing this in the evenings. I am very close with the basic setup and may start a test print tonight or tomorrow, definitely by this weekend.

CarlBosson

@Phaedrux
I ran in to a issue maybe you can help with?
When I home the axis individually or by home all, they work correctly. Once homed X, and Y work properly. But Z goes in the wrong direction. If I select +25mm it will go back towards the end stop. I have changed from S1 to S0 in the homing and config.g a few times trying different combinations but no luck. See below the config.g, homeall.g and homeZ.g
Thank you in advance.

@CarlBosson said in PID Tuning Procedure:

But Z goes in the wrong direction.

Keep in mind that Z0 is when the nozzle and bed are touching, and a Z+ move will make them move apart and a Z- move will make them move together. The position of the endstop does not have any bearing on the movement. If the endstop is at the Z0 end, it's a Z1, for low end, and the G1 Z homing move must be negative. If the endstop is at the Z max position farthest away from the bed, it's a Z2, for high end, and the G1 Z homing move must be positive.

If all that is as it should be and a Z move is going the wrong direction, you may need to change the direction of rotation of the motor set by M569 S1 or S0.
