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

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?

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).

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

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

Oh one other thing. I continue to get a G28 error about "Failed to enable endstops"
I just trying to test run the motors w/o having endstops.
Doing something wrong? -
Phaedrux, that was exactly what I wanted to know. Keep the Pi SD card in the Pi even when connect to the Duet. If I want (which I do), to run the Duet standalone then I use the SD card that came with the Duet. I have a separate high speed card reader/writer connect to PC USB port which is I'll try to set up the Duet card. Is this okay?

Sure, as long as it's formatted as described in the SD card link in my last post, and you have the Pi and the Duet ribbon cable disconnected.

you're not making it easy to help you; if you don't intend to use the rPi4 put it in a drawer and stop talking about it.

Hi Bearer,
I fully intend to use the Pi4, but it as been recommended to run the Duet standalone as a test to see if the motor respond to commands this way.
I guess it will help narrow down why it is not working in its present setup of the Pi4 and the Duet.
Thanks for all your help,
J
