@seeul8er i think he mean with a duet 3 with a pi attached which uses the object model as json response

This is a code from danal! There he differnece between the ESP and SBC Part.

def getCoords(self):
        if (self.pt == 2):
            URL=(f'{self._base_url}'+'/rr_status?type=2')
            r = self.requests.get(URL)
            j = self.json.loads(r.text)
            jc=j['coords']['xyz']
            an=j['axisNames']
            ret=self.json.loads('{}')
            for i in range(0,len(jc)):
                ret[ an[i] ] = jc[i]
            return(ret)
        if (self.pt == 3):
            URL=(f'{self._base_url}'+'/machine/status')
            r = self.requests.get(URL)
            j = self.json.loads(r.text)
            ja=j['result']['move']['axes']
            #d=j['result']['move']['drives']
            #ad=self.json.loads('{}')
            #for i in range(0,len(ja)):
            #    ad[ ja[i]['letter'] ] = ja[i]['drives'][0]
            ret=self.json.loads('{}')
            for i in range(0,len(ja)):
                ret[ ja[i]['letter'] ] = ja[i]['userPosition']
            return(ret)

@dc42 is it possible to switch on the duet3+sbc to a RFF2 response?

oliof

@jay_s_uk it doesn't work with my Duet3 board with SBC either.

I think it would be worth following the PanelDue implementation changes in the recent release.

seeul8er

Looks like we need to implement object model requests for RRF3.x+

It already does.

PCR

@dc42 Automaticy or is there a command?

I still have some PCBs left

Best

Maralb

@PCR Hello, Is it possible to buy one with Italian shipping?

PCR

@Maralb Sure! PM me!

Gold7even

@PCR Hello, i'm also interested by your pcb can you tell me the price for the pcb plus shipping cost to France, Thanks in advance.

PCR

Write me a PM;)

I have been having problems getting the system to work, I have the recommended components and the PCB by PCR.

I have flashed the ready made image from github but nothing works. Do I need to compile the firmware myself? I just don't know how to do that eg what pins are used, how do I get the wifi connection working? I don't know if you could help with detailed instructions or could you point me in the right direction.

I really want to get this working.

seeul8er

@appjaws IF you really got the recommended display and ESP32 everything works out of the box after flashing the firmware. No need to re-compile etc. What ESP32 Dev board are you using? Do you know your way around the ESP IDF? Connect the ESP32 to your computer and execute

idf.py monitor

Check the Espressif Docs on how to install their tools in case you do not have them already.

jay_s_uk

Would be good to see support for machine/status rather than rr_status.
I have a number of machines where I'd like to use this but currently can't due to it not supporting an SBC

PCR

@appjaws can you make a Picture of the ESP with my PCB. Some Users Here are using it without Problems !

appjaws

SUCCESS I had a bad joint, now fixed, thank you for your help.
However, the unit is not connecting to the router, it says Not connected to network or UART.t
The SSID was recognised and I have inputted the wireless network password 3 or 4 times. Is there a way of checking that the correct password has been entered, I fine the screen very small for my cubby fingers.t
Any suggestions on how to chase this down?

I am now connected to my router but the Duet is not recognised, the message says " No response from the printer!"
The duet is connected via ethernet, did I need a WIFI version? Is there any other setup needed?

Thanks for all help

PCR

@appjaws put the ip of the duet manually in if you can!

appjaws

@PCR tried that the screen shows 192.168.001.069 and reprap password is reprap

Greetings All,

I've ordered the PCB and ESP from @PCR. I'm looking at the BuyDisplay.com page, and want to confirm some selection items before ordering.

Pin Header or FFC connection for the 4-wire SPI?
Power Supply Type (3.3 or 5.0V)?
Font chip (instructions say one isn't needed, but there is no selection for no chip -- so would any of the selections work?)

https://www.buydisplay.com/lcd-3-5-inch-320x480-tft-display-module-optl-touch-screen-w-breakout-board

Also @PCR - you mention needing 2 20-pin male connectors and that you were thinking of including them... Did you include them, or should I source those elsewhere?

Thanks!

John

Sounds wrong: Leading zero is not valid in IPv4 I think. Try 192.168.1.69. Make sure there is no space in front of the password and IP.

@JohnOCFII

Pin header for PCRs PCB
3.3V (5V works as well but not with the PCB of PCR as far as I remember - just a wiring thing)
Just select nothing for the font chip. Leave it to the page default --Please Select--. However font chip or not should not make any difference.

Excellent! Thanks for the quick reply.
