commissioning a new custom 4'x4'x4' printer..have questions

[Jim46]

Hi everyone,
I've never used the microsd card. I'm assuming that if I have the config.reprapfirmware.org and the DWC (Rpi4) connected via the router that I don't need to use the microSD card. Also, does the RPi4 and Duet3d update automatically if changes are made on the PC or do I need to the same thing using the RPi4 screen (Not the PC)?:

[Phaedrux]

If you use the rpi the duet doesn't need an SD card. That's correct.

Also, does the RPi4 and Duet3d update automatically if changes are made on the PC or do I need to the same thing using the RPi4 screen (Not the PC)?

I'm not exactly sure what you mean by that. If you mean that you're making changes to config.g through the web interface, then that's all you need to do. Those changes get saved to the rpi which is in communication with the duet.

[Jim46]

Thanks Phaedrux, that helps a lot. So, to be clear I don't need the microSD card in the Duet to make the system work?
Still trying to figure out why the motors aren't being activated by the g-codes while trying to test them. Any ideas?

[Phaedrux]

You only need the SD card in the Duet when running in standalone mode without the Pi.

Are you sending a command to set the axis as homed before trying to move them? They won't move unless in a homed state. For testing, you can send M564 H0 S0 which will allow you to jog the axis as much as you want, but be careful because it won't stop itself at the physical limits.

[Jim46]

Presently, the motors are sitting on my work table, not installed in the printer.
I've run M65 H0. then G91. Followed by G1 H2 X20 and Y20 and Z20. And, then M654 H0 S0 followed by G91, then G1 H2 X10, and Y10 and Z10. The microSD card is not installed in the Duet. The RPi4 is connected to the router via Lan Cable.
Now movement when directed by the PC or when doing the same on the RPi4 screen. Its a mystery!
Here is the PC screen:

[Jim46]

Opps bad typing its M564

[Phaedrux]

Try sending G92 X100 Y100 Z100
That will force the axis as homed and at the 100mm position. You should then be able to use the job buttons in DWC?

What versions of firmware, dwc and pi framework are you using? I'm thinking you may have some updating to do, if you're not already up to date.

[Jim46]

Greetings Phaedrux,
M115 on my PC raspberrypi (DWC) gave back the following:

FIRMWARE_NAME: RepRap Firmware for Duet 3 MB6HC v0.6 or 1.0 FIRMWARE_VERSION: 3.0 ELECTRONICS: Duet 3 MB6HC FIRMWARE DATE: 2020-01-03b3.

The Duet/Pi/24vMeanwell-PS are all on and appear to be running ok.

Nothing happened with G92 and G92 X100 Y100 Z100. I did it from the PC and on the RPi4 screen.
It just shows a green table on the screen with the code that was input and a check mark.

Thanks for your help and sticking with me.
What next?
Jim

Yes, but afterwards were you able to use the jog buttons?

[Jim46]

Hi,
I re-ran the RRF Config tool again and update the files into the raspberrypi (DWC) then re-ran the g-code sequence
M654 H0
G91
G1 H2 X20 and Y20 and Z20
then
G2 X100 Y100 Z100
No movement.
tried the jog buttons also, no movement
did get pink tab errors:
G2 X100 Y100 Z100 error: code has been cancelled
G2/G3: no I or J or R parameter

what does this tell you?

With this one I think you meant G1. G2 is an arc move that needs additional parameters to define the arc.

Are you sure the motors are connected correctly? Do you hear any sound from the motors? Does it change when you send G92 X100 Y100 Z100? I believe that should energize them.

I think at this point it's probably going to be a good idea to update the firmware and pi environment. Have you done any updates thus far?

[Jim46]

HI Phaedrux,
Not sure about...
"a good idea to update the firmware and pi environment. Have you done any updates thus far?"
Today, I re-ran the RRF configtool.reprapfirmware tool. It gave me similar files to those shown on my 12 April post. I uploaded them on my PC to what I think is the DWC screen labeled as raspberrypi.

The raspberrypi system files show everything except Duet files as 4/15/2020: 6:15pm. The Duet files are all 3/16/2020.
Is this the update of the Duet you are referring to? I'm very new at this.

On the Pi screen, I did sudo apt update and downloaded package information from all configured sources, I hope the system knows what the latest updates are.

then I ran sudo apt full-upgrade it then download all the updates and installed them, I hope.

I waited (it seemed pretty quick on the Pi screen) for the updates to be installed on the PC raspberrypi screen (DWC?).

Do you have to re-run the RRF Configtool.reprapfirmware.com each time you try to run the raspberrypi (DCW)? do the files have to be unzipped or does it do it automatically when downloaded to the raspbeerypi system on the PC? I set the system size again 0-1000mm on all three axes. set the steppers to belt drives at 53.33 on all axes. deleted all the tools, I hope.

At any rate, I did it again on the PC and ran the g-codes
M564 H0
G91
G1 H2 X20 and Y20 and Z20...no movement yet
G92 X100 Y100 Z100
then tried the jog motion buttons...no movement
I seem to have a new message on the system page... Drive is Unmounted...what does that mean?
I'm trying to upload 2 pics of my screens... Having server parsing errors...
Ill try it later

Yes, and no. There are two sources of updates. run grep duet3d -r /etc/apt to check which one(s) you're using. You can also run apt list 2>/dev/null | grep duet to list all the relevant version numbers currently installed.

And you've jumped right into the deep end to boot!

It may be easier if you set the rpi aside for the moment and tried to get the Duet 3 setup in standalone mode. Once you have commissioned the machine, you can re-integrate the rpi, by then there will likely be some more stable and fully featured versions available.

[Jim46]

Hi All,
thanks for all the comments and advice. I'll see if I can run the Duet3D 6HC on its own. Do I have to install the microSD card to do this. Or, if I have the Duet connected to the router would it be easier to get working?
Here are the screen shots I hope
Nope: Error
Something went wrong while parsing server response.

[Phaedrux]

Yes, to run the Duet 3 in standalone mode you would need a SD card (formatted as fat32) in the Duet 3 SD card. It would need your config.g and all the other files present. The Duet 3 would be connected to your network via the ethernet port. You would connect to it via the DWC using the duet name or IP address provided by the router.

For the photos, can you try dragging them onto the forum post window, or even copy pasting them? That may work. Otherwise you may be able to put them on dropbox or google drive and sharing a link to them here.

[Jim46]

my pic file sizes are half the size limit 4096 kB and yet I am still the error: Something went wrong while parsing server response. I'll try other methods.

[Phaedrux]

test upload

[Phaedrux]

Seems to work for me on chrome on a mac. What browser are you using?

I get this about 50% of the time lately. Refresh the page and retry works 11 of 10 times in my case. Also using chrome.
