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

[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?

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.

test upload

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.

[Jim46]

Lovely test upload

I moved to chrome and it worked. The Edge browser didn't work after rebooting.

You can see in the middle pic a message on the systems table that the drive is unmounted. Not turned our or worse?

Here is something most curious.

When RRF Configtool.reprapfirmware.org finishes and generates the system files:
bed.g
config.g
homeall.g
homex.g
homey.g
homez.g
pause.g
resume.g
sleep.g
stop.g
which in this case are unzipped
give this screen with varying files, shown here...

Yet, when I send to the PC download in order to load into raspberrypi (DWC), the files are all only 1 kB

Is this wrong? if not what should it be?
thanks i advance,
Jim

[Phaedrux]

I think windows is just rounding up to 1KB. Possibly due to size on disk.

If you open the files in a text editor, do you see the contents? That's what matters most.

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!

I presume you mean "No movement". Please send the following commands to check that the drivers are assigned correctly and have the currents set:

M584
M906
M913
M92

[Jim46]

Hi Guys and Gals,
After a couple days of tech grimlins having Comcast reset the cable modem and Linksys reset the router, I'm back trying the all the commands on the PC DWC which were recommended. Still no motor movement.
Q: I have a RPi4 connected to the Duet3D. THe Pi has its microSD card installed and seems to be working well. Re-reading the Duet3D start-up instructions https://duet3d.dozuki.com/Wiki/SD_Card trying to set up to run Duet3D standalone to see if that works to get the motors to respond.

BTW, the DWC (raspberrypi) screen on the PC continues to say: The following axes are not homed: X, Y, Z.

Ok, now what as I thought the codes sent stepped past the Home requirement sent my motors are just sitting on my desk?

as always your help is deeply appreciated.
Jim

[Jim46]

Oh, the SD card instructions seem to say one needs to put the Duet3D SD card in the RPi4 when its a connected setup. Is this true? If so, then could it be why the motors don't respond to the commands?

@Jim46 said in commissioning a new custom 4'x4'x4' printer..have questions:

when its a connected setup.

if you're refering to using the Duet 3 with the Raspberry Pi and Duet Software Framework, then yes, SD card goes in the Raspberry Pi and only in the Raspberry Pi.

however, something doesn't add up, because if the Pi is working it already has an SD card it it with the operating system for the Pi. The files that goes on the SD card in stand alone mode then needs to be put into /opt/dsf/sd on the SD card that also has the Pi operating sytem (where /opt/dsd/sd becomes a virtual SD card that DSF present to the Duet 3).

[Jim46]

HI,
the SD card in the Pi4 came with it and was set up according the the https://www.raspberrypi.org/forums/. It is still in the Pi. So, the question boils down to is it required when Duet3 and Pi4 are connected to use the Duet3 SD card in the Pi? So, I don't know it the Duet Software Framework is on it. How to find out?

Duet3 standalone operation: it seems clear that you use the Duet3D SD card. I now have to figure out how to set up the Duet3 SD card.

cheers

[Phaedrux]

If you intend to use the Duet in standaloen mode, disconnect the pi. You can leave the SD card in the pi and use a seperate SD card for the Duet standalone config. That way you can go back to the connected Pi more easily in the future.

To prepare an SD card for the Duet, see here: https://duet3d.dozuki.com/Wiki/SD_Card
