@dc42 said in Pinda2 to Duet3 toolboard:

Also, the ^ pullup enable should not be used on Duet 3 IOx_in ports..

Could you please elaborate a bit more on this, why is that ?

The pullup resistor (internal to the MCU, so not something we can remove) never needs to be enabled when using Duet 3 IOx.IN pins, and doing so worsens the noise margin.

...and does "Duet3" do include Mini variants ?

Yes.

i find my end-stops (hall effect) work much better with ^ rather then without
If i remove ^ i get false triggers... so this appears a bit strange tbh..

@oc_geek on Duet 3 Mini 5+? @dc42 do you have a view on this?

@oc_geek same story I tried and i gives me false triggers on Pinda 2 too
EDIT
I did the first tests without cycling power, after a power cycle, now it works ok without Pullup

@dc42 I still do not know if using ^ will damage my duet3

@martin7404 No I don't think it will damage the board. I think the worst case is just lowering the noise floor. But it seems to work BETTER for you?

No it won't.

TO warp up
In the end I found that it is working both ways with or without pullup.
I ended up changing pinda2 to superpinda, as far I got one delivered and super panda is working flawlessly with the same config

@martin7404 Just curious, where were you able to purchase a superPinda? Prusa only sells them to registered owners. Asking because I would like to get one as well.

martin7404

@kb58 prusa online shop, I have mk3 printer. You can always ask somebody local for you with original prusa to order 1 for you

Hi there,

I wonder if I can connect a original Prusa Super Pinda the same way the pinda 2 is connected?
The Super Pinda has only 3 wires instead of four (white is missing).

I assume this is based on temperature independence now.

One thing in addition, does anyone know if the Super Pinda uses 5v only? I read a couple thing like 5v-24v and the higher the more accurate it should be.... is this a rumor, or proofed?

Thanks in advance.

Cheers

@sn1kk3r5 I switched to superpinda and it works. Just ignore the white wire on my drawing in first post
