It works

@jay_s_uk Damn ... those who can read have a clear advantage

as soon as you do it right, it works

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

@dc42
now the update is visible and working

@fcwilt
it lives ... it breathes

the {} were the solution

many many thanks: D

@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

@droftarts said in Flashing firmware on Mac OS X:

@blacksheep99 Do you mean when you downloaded the zip file from Github it automatically extracted it? That's a browser setting. If you're using Safari, from the menus select Safari > Preferences, and untick the 'Open "safe" files after downloading' on the General tab. Zip files will then not automatically extract. Other browsers have this 'feature' optionally set in preferences, too.

or go in the waste box and drag&drop to desktop

hello jay my friend

Does that sound like everything is completely normal and intentional?

So is not a bug ... but a feature

With the new release 3.3RC3 it works

Now I have to put the code for power off the shelly-pm in my shutdownsbc.service

next adventure for me

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

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
Too bad... I guess I'll have to wire it differently.
Or will that be an update in one of the next versions?

Hello.

I copied this code snippet from the wiki and adapted it to my connections.
Unfortunately, it doesn't work as intended. The fans are always on (Temp in DWC is 36,9 °C).
But they're supposed to only start at 40°C.

M308 S10 Y"mcu-temp" A"MCU" ; configure sensor 10 as on-chip MCU temperature sensor
M950 F8 C"2.out3" Q500 ; create fan 8 on pin 2.out3 on MB3HC Board #2 and set its frequency
M106 P8 H10 T40:70 ; set fan 2 value

@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

@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
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

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

@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
