Considering Duet3, New to RPi

@Dizzwold said in Considering Duet3, New to RPi:
It looks like I'll be going with a Duet3 without an SBC / RPi. After-all, I'm only a hobbyist and it's not a source of income.
Have you considered the Duet 3 Mini? It's available in both WiFi and Ethernet versions. Both have the option to connect a RPi, in case you want to do that later.
We have another production batch of Duet 3 Mini being assembled and tested this week and next, so availability of Duet 3 Mini should be good by mid February.

Hi dc42 & Veti,
Is that the Duet3 Mini 5+ ?
If I went with the Duet 3 Mini (I believe it has 5 stepper drivers), If I later decide to go with a triple z axis would, therefore needing an additional Stepper and Driver, what / which add-on would be the best option?
Also I can see the documentation on the Duet3 Mini 5+ and the add-on accessories, but no prices. Do you have any prices for the above items?
Can I pre-order if I decide to go with the above?

@Dizzwold There is an expansion board that will allow 2 extra drivers to be added.
The mini 5+ also supports can boards so you could add a toolboard or a duet 3 3HC if required -

its already available, but has been sold out.
-
Hi Veti,
Yeah just found the price on E3D, but like you say, sold out.
Thank you.

@Phaedrux aren't most of the services run from the Pi instead of the duet, leaving the duet just handling IO? I thought that especially at high speeds having a Pi would lighten up the duet MCU.
Also updating is much faster/easier with a pi

Hi Jay_s_uk,
Okay thank you.

Hi matt3o,
Oh, another positive thought on the RPi.
LOL, commence the battle of RPi users vs non RPi users.
As a hobby user, so light use, would I benefit from having a RPi?

define "hobby"
many users here including myself take the hobby very seriously 
If you connect to the duet from 1-2 PCs and you print at "human" speeds I don't think it makes any difference. Probably it makes no difference for 90% of the use-cases. Personally I use it mostly for the wifi and for the good performance ssh connection.

Hi matt3o,
Lol, Yeah like how longs a piece of string...
I think most of us take their 3d printing seriously, as we all want the best results we can get form the equipment we have.
The other way of looking at it as a hobby is I don't use it for a living.When I purchased the printer, cost was an issue, and wrongly or rightly I have to live with the choice I made.
I was looking into the possibility of getting a duet in the future, but as I've now killed my motherboard, my arm is now forced into getting one and a Duet it will be.
I've had lots of answers to questions I've not yet asked, but these are all welcome, as I would have been asking these questions anyway, so I'm very grateful for all this input.
Basically, I have a dead printer, I'm a mac user, I wish to have a PanelDue along with a Duet, I wish to be able to not only use the PanelDue but also connect it to my mac that's 2.5mm across the room, I would like to (but not essential) Connect to another mac in another room, I don't have (is it cat6 cabling) a wired network in my house, I have wifi, but have some TP Link Pass through Powerline adaptors.
Once I have a Duet, PanelDue and my printer functioning again, the next thing maybe a Mic6 bed with 3 point levelling and possibly a 3rd Z axis. -
It sounds to me that the Duet 3 Mini WiFi will meet your needs well. For the display, you can use either a PanelDue or a Mini 12864 display (using ST7567 controller) with it, or if you use a Pi then you can connect a HDMI touch screen to that.

Hi All,
So it looks like I'm swaying toward the Duet 3 Mini 5 as few have commented on. This way I can also upgrade ‘if and when’ needed.
It looks like I'll have to wait a few weeks before any more Duet 3 Mini 5's are ready, No Pressure David. LOL
I am most grateful for everyone's input and advice.
No doubt I'll be back again with yet more questions, but for now I think I have a bit of reading to do, to familiarise myself better with the Duet system.
Also any more comments and / or suggestions are very welcome.
Thank you,
Dizzwold.

With the RPi,
Do you just change the ssid and password in the wpa_supplicant.conf file to your router settings, wire the 26-40way into the Duet and RPi, put the SD card in the RPi then power the Duet?Do you have to flash the RPi with anything first then do the above?
-
@Dizzwold https://duet3d.dozuki.com/Wiki/SBC_Setup_for_Duet_3
Yes you've got it. There is a custom Pi image as well. Though you can also do it manually if you wish.
-
Hmm,
I have no screen attached to the RPi.
I've tried opened http://duet3.local , but nothing opens, Disabled VPN and ran IP Scanner, but don't see anything?
I must be missing a step?
-
You're using wifi? Something must not have worked adding it to the network. Can you add a screen and keyboard to see what's going on?
-
I have a desktop mac, the Duet and RPi are on the desk in front of it, so can either connect with Ethernet of Wifi, but no dedicated screen or keyboard
-
If you connect via ethernet it should pick up a DHCP address from your router, so check your router to see if it's actually getting an address. Then try to connect to that via SSH as described in the SBC setup link.

You might have to enable ssh before you can SSH into it.

-
Isn't there an interface of some description like the Arduino's have an IDE?
I'm surprised at how hot the thing gets as well.
Something I've just done by mistake was power the unit without the SD card. The Red LED stays on and the Green LED flashes. With the SD card in, this only happens when first powering up , then they both go out?
