Hello everyone,

I'm struggling with setting up my duet2 wifi with a mini ir sensor. I have it hooked up right (it flashes when I move a piece of paper or anything up to it) but I'm stuck at the m558 commands. When I send m558 p1 it returns:
Error: m558: missing z probe pin names

My config.g file under z probe says:
M558 p1 c"zprobe.in" h5 f120 t6000
G31 p500 x0 y0 z.25
M557 x15:195 y15:195 s20

What am I missing lol

Thanks everyone!

Ohh and what will I need to do to map the bed to the sensor location?

@dc42 When i use rr_model the information i get back is null. when i go to the page in my browser it doesnt have any values for any of the fields either. im using rrf 3.4.6

Is it possible to just query whatever the source for the DWC % complete? I just need the number.

@dc42 said in How to connect nodemcu (arduino) to DWC over wifi:

@andnosobabin I recommend you use rr_model instead of rr_status because we will likely discontinue rr_status in a future firmware version.

To authenticate, use rr_connect to establish the connection with the Duet. After that you must either send a request such a rr_model frequently (AFAIR the timeout is 8 seconds), or send rr_connect again before rr_model.

Awesome I'll amend that thanks!
What is the format for the rr_connect request?

Hello,
I have been working on some automated lighting scripts for my printer. So far I've managed to get a serial connection between my duet2 WiFi and a nodemcu and used this code to control multiple strings (ws2812B) to show error alerts, job completion, etc etc etc...

Now what I really would like to do is have a string of lights that will show actual percentage in real time filling the string up as the print progresses.

My thought was to have the node go to http://192.168.1.199/rr_status?type=3 (the local address of my printer) and then use that data to run the script accordingly.

The problem I've ran into is that I can only access that page from a machine that is currently logged into the DWC.

Is there an easier way or could someone explain how I can get the node to authenticate itself?

Thanks!

dc42 said "if you don't have stepper driver 11 connected then you don't need an Arduino, just a fast level shifter (e.g. 74HCT08) to boost the signal to 5V. A limitation is that on the Duet WiFi/Ethernet, using the M150 command to change the lighting will pause movement briefly. This is because there is no dedicated DMA-controlled SPI channel for LED lighting on the Duet WiFi, so the firmware has to disable interrupts while it sends the data to the LED strip.

if im understanding this correctly i would connect my DI to Pin 6) EN 11 (LCD_RS) the vcc to 5v and gnd to ground using a converter. Then what do i put in my config file to call that pin for the M150 command and how do i set it up for however many leds are in the strip?

Thanks

@jay_s_uk That was exactly the problem. Thanks!. I took something really close in size glued it on and no more issues with erratic behavior I think. Im not all too sure I have everything setup correctly tho as my height map looks as shown. Any suggestions?

@jay_s_uk ill have to rig something up to block the stray ir then, i mucked up the contacts on the capacitor and dont have a replacement on hand. Thanks for your reply!

@droftarts said in mini ir on duet2 wifi:

M558 P1 C"zprobe.in" H5 F120 T6000

Thanks for the reply. When high above the board it shows 0. I will have to make a "dummy" to put in that area as i dont have a replacement and didn't leave much to resolder with.

@norder The sensor is mounted 1.5mm above the bed and the wiring seems to be correct as the sensor DOES function properly but I seem to not have the correct settings and it isnt behaving as i think it should. I will attach pictures to confirm this for you tho.
P.S. The capacitor is oriented differently because i moved it as it was in the way of a previous printhead not the current one.

Thanks for your assistance!!

@norder I dont remember what was going on back then its not doing that now tho. I appreciate the quick reply tho!

@droftarts I don't remember what was going on back then its not acting that way now tho it just wont trigger at a low height to calibrate it.
