Now this

The accelerometer is OK, tested on other printer.
Used multimeter to verify connection pin to pin.

Tried another IO for CS/INT

@dc42
Is there a way to test port functionality for accelerometer on Mini5+ Lan version

I suspect that something is wrong with this board as it will not function.

@tecno are you using the same cabling on both machines, or different cabling? The most common issue we see with these accelerometers is that the CS signal is sensitive to noise, which it can pick up from other signals in the same cable. Better cabling fixes the problem, however a small capacitor between CS and ground on the LIS3D[S]H board would probably fix it too. 220pF might be a suitable value.

@dc42
Two different cabling, on this Delta I have two different shielded cables one for VCC/GND/CS shield grounded on Duet side.

Will try cap

tecno

@dc42

Same with cap CS to GND /// This does not work on my Chiron. May wrong value cap

dc42

@tecno you could try 470pF or even 1nF. If that still doesn't work then I would suspect a bad connection.

The error message you reported earlier concerning INT1 suggests that the INT line was not connected or was not configured correctly.

@dc42
Will do, back shortly. PS did work on my chiron !

Sorry NoGo

@dc42

Just made a very short cable just to verify if port on Duet board is busted or not = it is not.

So the long cable I have is just too much ~2.10m, Maybe I can cut it down to ~1.6m, need to have space to move all axis for input shaping.

tecno

Did cut down the cable = NoGo

tecno

Is it really that bad that my accelerometer boards are useless due to cable lenght?

Is there any development as regards Smart effector to include accelerometer?

dc42

@tecno I am pushing for the combined Smart Effector and tool board to be done soon. We will increase the size and the rod spacing (perhaps from 55 to 70mm) to accommodate a small direct drive extruder, and maybe change the hot end mounting to suit the E3D Revo Voron hot end. Does that sound OK?

tecno

@dc42
That sounds to be very good solution to get all signals as short as possible.

If you need a beta tester I am here awaiting

FWIW, it sounds fabulous to me - it has been mentioned a number of times, and I expect I'll place an order as soon as I see it (I'd even pre-order). Personally, I'd prefer a Revo Micro (because I currently have a revo micro on my smarteffector, so it avoids additional purchases) but I'd still buy if I needed a new Revo heatsink.

My preferred extruder would be orbiter (which I have on other printer and am happy with), but I do note that it's more eccentric (about the filament path) than some other options.

@achrn
I run a watercooled Phaetus Dragon with Orbiter V2.0 so it only needs a new SE board.

@dc42 awesome.....can´t wait for it!!!

Remind me, is that one "bolt compatible" with the Mosquito from Slice Engineering? If it is; Sign me up for a pre-order!
