Thanks for your help @Veti and @dc42 !
I've encountered a SM220A is a 2.0 AMP Surface Mount Schottky Barrier Rectifier, this is the datasheet
Can I replace the d1 diode on the board for this one?
In my region(BR) its so dificult to find specific components like this in warehouses, so i try to look in some waste electronics boards.

Hello friends!
I have a core xy printer equipped with an integrated pcb version of the paneldue 5i v1.0, last night during a maintenance the panel decided to jump off the bench and hit the floor and damaged some (4) components.
Two of them I don't know where they ended up, because they came off the board, they are the diodes DA1 and D1, could someone tell me which diode models I need to replace both?
The other two components that broke are the capacitor C2 and the coil L2, but these are still attached to the board and I can read the model of both.
I believe that even with the impact the lcd continues to work well.
I appreciate if you can help me, and wish me luck please
I've attached some pics of board!

I've worked yesterday on fan wiring, and now it's working as expected.
Thanks to everyone who helped me!

I hope that at some point this topic can help someone too.

@Veti said in M106 does not work:

out of curiosity. how did you managed to do that exactly?

Just wired together negative fans pins with gnd endstop pin, from print head.
And opened the single wire to respective pins in the duet enclousure.

@dc42 I've shorted negative fans connection to ground, sorry for inexperience

I've been checking this right now, wired another 24v fan on outputs, with other clean wires too, and both was working as spected.
So i'll working on wires of the FAN0 and FAN1.
Aparently don't have any damage on my duet because this,.

Do you think this might have damaged something?

@dc42 said in M106 does not work:

Are the Fan1 and Fan2 outputs working properly?

When i mesure the voltage on the FAN 0 output (without fan connected):

• startup the 3d printer (0V) - as spected;
• send M106 P0 S255 (23,4V) - as spected;
• send M106 P0 S0 (0V) - as spected;
• with control bar on web control (0V~23,4V) - as spected;

Now when i mesure the voltage on the FAN 0 output (with fan connected):

• startup the 3d printer (23,4V) - not spected;
• send M106 P0 S255 (23,4V) - as spected;
• send M106 P0 S0 (23,4V) - not spected;
• with control bar on web control (stay on 23,4V) - not spected;

What can make the fan turn on(in high) everytime, even the 3d printer startup, and can't control them with gcodes or web control?
I didnt make same tests in FAN1 channel, but i'm sure the cause it's exactly the same
The Fan0 specs is: Radial brushless fan dc, 24v, 0.08a;
The Fan1 specs is: E3D original fan dc(titan aero kit), 24v;

I'll try to test one by one with a multimeter.
First step with the cooling part fan output(FAN0), and watch any voltage difference after send these commands:
M106 P0 S0
M106 P0 S255

@dc42 said in M106 does not work:

After you send that command, what does it report if you send M106 P1 with no other parameters?

I've tried this in other moment, the firmware report supposed speed changes, but the fans stay on high speed every time

@dc42 said in M106 does not work:

Are the Fan1 and Fan2 outputs working properly?

I'm thinking they're not.
What i can do to have assurance about this?

Thanks for your care Mr. @dc42

Hello again.
I've been upgrading my firmware version to newest release (2.04)
But still have the problem.
Also try "M106 P0 S0 H-1" send by web control/panel due, and any speed changes on fan, everytime on full speed, and the other one too.

My firmware version is 2.03 beta 2.

I've been upgrade since jun, and since then haven't check for updates.
Do you think this could be it?
