@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 · 28 Mar 2025, 19:21

@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 · 28 Mar 2025, 20:08

@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 · 28 Mar 2025, 20:09

@CrazyCreator did you install the fan mosfet?

jay_s_uk · 28 Mar 2025, 20:10

@CrazyCreator looks like you didn't

@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

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 · 30 Mar 2025, 16:45

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

CrazyCreator · 30 Mar 2025, 16:49

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

jay_s_uk · 30 Mar 2025, 18:26

@CrazyCreator yes, that's right

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 · 19 Apr 2025, 05:28

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

CrazyCreator · 19 Apr 2025, 10:20

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

And it's connected like this:

jay_s_uk · 19 Apr 2025, 11:34

@CrazyCreator then just a normal end stop then

CrazyCreator · 21 Apr 2025, 15:55

@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?

jay_s_uk · 21 Apr 2025, 17:23

@CrazyCreator yes, if it's not connected it'll read like that. It'll also read like that if it's not calibrated

CrazyCreator · 21 Apr 2025, 17:33

@jay_s_uk
That will be the next project. Calibrating the scanner... Yeaaaaah

CrazyCreator · 22 Apr 2025, 21:53

@jay_s_uk
Can you help me again?

When I send the MicroProbe to probe the bed, it moves to the planned point and the pin pops out briefly but then goes back in immediately
and the bed stops.
The DWC Show: Z-Probe 0

Then the error message appears:

The config.g for this:

; Endstops

When i try the other way in config.g with !

If I connect it like this, the MicroProbe works. The pin pops out and is triggered by the bed, and the bed stops.

BUT then I see a red 1000 on the display.

But the homing works perfectly fine, even though it says 1000 in red. That's kind of surprising, because that's not how it's supposed to be, is it?

Maybe you can take a look at my configuration?

Attached are config.g and the homing files:
config.g
homeall.g
homex.g
homey.g
homez.g

Maybe

@CrazyCreator the V2 is inverted so your second config is correct
