@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

@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
