Fly-SHT36 Max V3 RP2040 Based CAN-FD Toolboard

@jay_s_uk
This means, whenever there is a RRF update I have to update manually with your Duet3Firmware_SHT36MAX3.uf2 downloaded from github and uploaded then via the DWC?

[jay_s_uk]

@CrazyCreator correct

[CrazyCreator]

@jay_s_uk
Many thanks for your support ... i think i write the next days for config the new z-probe-scanner

[CrazyCreator]

@jay_s_uk
So ... Now i have the first Question

; TestFan - Zum testen des FAN Port's am Fly-SHT36 Max V3
M950 F10 C"124.out13" Q500	; create fan 10 on pin gpio13 on Fly-SHT36 Max V3 Board and set its frequency
M106 P10 C"TEST-Fan" H-1	; set fan 10 value. Thermostatic control is turned OFF

I wrote this in my config.g, but without success.
The FAN is connected to the GPIO13 FAN0
Is a 24V Fan and the jumper is setting on the VCC

[jay_s_uk]

@CrazyCreator thats incorrect naming
the correct names to use can be found in this table here

@jay_s_uk Why didn't I see the button? Thank you.

[CrazyCreator]

@jay_s_uk
So the entry for my test fan now looks like this:

M950 F10 C"124.out1" Q500 	
M106 P10 S255				

It also appears in the frontend, but when I increase it with the slider, nothing happens.
but on SHT a blue LED lights up synchronously to control the slider
I think I need to test my cables and plugs

[CrazyCreator]

@jay_s_uk
I've now checked all the cables and crimped a new one.

But the fan remains silent.

I've attached a picture with the perhaps silly question: Did I set the jumper for 24V correctly?
There's 24V at the connector above, I measured it, and the fan is a 24V fan.

[jay_s_uk]

@CrazyCreator did you install the fan mosfet?

[jay_s_uk]

@CrazyCreator looks like you didn't

[CrazyCreator]

@jay_s_uk
Oh dear... How could I have forgotten that? I put the MOSFET in a small bowl so I wouldn't forget it!!!

Now the fan works too

[CrazyCreator]

So... Let's move on

Since the SHT36 is working so well, I got a toolboard yesterday and now want to connect 4 SHT36s to it.

Is the CAN wiring in my ugly drawing correct?

[jay_s_uk]

@CrazyCreator that looks fine.
You'll need the bypass jumpers in place as these are being treated as stubs.

[CrazyCreator]

@jay_s_uk Currently, all 8 jumpers are plugged in. I think that's correct, right?

[jay_s_uk]

@CrazyCreator yes, that's right

[CrazyCreator]

Today I finally got back to my printer and have a little bit of work ahead of me for tomorrow.

I would like to connect a GL-8FN1 sensor as an X-Endstop to the SHT36.
Unfortunately, I've only found these two options:

And now I'm not sure if the "HVIN" input corresponds to my sensor.

I'm already using the same sensor as a Y-Endstop. It's connected to the MB6HC, of ​​course:

M574 Y1 S1 P"!io2.in" ; configure switch-type (e.g., microswitch) endstop for low end on Y via pin io2.in

Unfortunately, I'm currently a bit unsure about which pins I should use on the SHT36.

[jay_s_uk]

@CrazyCreator looks like it runs on 12-24v so same has the HVIN

[CrazyCreator]

@jay_s_uk
It's this sensor: https://s.click.aliexpress.com/e/_oo1zqJ5

And it's connected like this:

[jay_s_uk]

@CrazyCreator then just a normal end stop then

@jay_s_uk Hello ... Ready now

Only if you interested, there the part from config.g

I think this is normal, because the Scanning Probe is not connected?
