Fly-SHT36 Max V3 RP2040 Based CAN-FD Toolboard

@jay_s_uk
So the entry for my test fan now looks like this:M950 F10 C"124.out1" Q500 M106 P10 S255It 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
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.
-
@CrazyCreator did you install the fan mosfet?
-
@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?
-
@CrazyCreator that looks fine.
You'll need the bypass jumpers in place as these are being treated as stubs.

@jay_s_uk Currently, all 8 jumpers are plugged in. I think that's correct, right?
-
@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.inUnfortunately, I'm currently a bit unsure about which pins I should use on the SHT36.
-
@CrazyCreator looks like it runs on 12-24v so same has the HVIN
-
@jay_s_uk
It's this sensor: https://s.click.aliexpress.com/e/_oo1zqJ5And it's connected like this:
-
@CrazyCreator then just a normal end stop then
-
@jay_s_uk Hello ... Ready now
MicroProbe and Proximity Sensor connected and working (in Testconfig).
Only if you interested, there the part from config.g

I think this is normal, because the Scanning Probe is not connected? -
@CrazyCreator yes, if it's not connected it'll read like that. It'll also read like that if it's not calibrated

@jay_s_uk
That will be the next project. Calibrating the scanner... Yeaaaaah
-
@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 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.gMaybe
-
@CrazyCreator the V2 is inverted so your second config is correct
-
@jay_s_uk
And this
is ok? -
@jay_s_uk and maybe @jumpedwithbothfeet said in Fly-SHT36 Max V3 RP2040 Based CAN-FD Toolboard:
... , watch out for the ribbon connectors I found them quite tricky!
I managed to get the ribbon cable in on the side of the probe, but on the board itself... No chance. It doesn't slide in deep enough to stay in place. It keeps falling out.
Do you have any tips that might make this easier or even possible?
Is there nothing on the socket itself that you need to unlock or open before inserting the ribbon cable?
