For the life of me, I cant get this to run 'correct' (I don't think).   I followed the PinScape Build Guide v2 and still seem to have some issues.  I even found and followed  the Major Frenchy online video's (thanks BTW)

 

In Play---12 v  ATX jumped Power Supply (also supplying 5v for LED Matrix and side LEDs which works fine); LedWiz (running fine for all buttons and Contactors (8); and SainSmart 12 V/5V board- (new to install and using only as a relay).

 

DOF runs fine minus the Shaker--no other cabinet issues that I am aware of:

 

Current Wiring Setup:

12V in and Ground from ATX to Power on Sainsmart (distributed from block)

Output from Sainsmart board to LedWiz-   In this case port 7. 

12V from Power Supply to Common on Sainsmart relay board- Port 7

Ground from Power Supply to Positive of Shaker

Negative from Shaker to NO of Sainsmart- Port 7

Diode between Shaker motor wires. 

 

I have configured DOF to have Shaker on output channel of LEDWiz and turned the intensity down to 1 to 12-  At 48 it shakes the holy hell out of the cabinet. 

 

What I see happening:

 

Shaker engages but buzzes first and then shakes. Feels off....

 

DOF question---without a voltage adjustment---anyone have a good intensity setting for the Stern Shaker Motor (from Pinball Life)-  no control board in play.  Mine are 1 (min) to 15 (max)

Wiring correct?  I will admit---it seems a little off to me.

 

 

Thanks for the help and support!

If you are using a relay board then you only have two intensities,0 and 255, that is on and off.  You cannot use Pulse Width Modulation (PWM) via a relay.  On some occasions if you have a relay on a PWM output you can get "buzzing" of the relay as the power is turned on / off very quickly which is effectively PWM.

 

Set your intensity to 100% / 255 / max when you go via a relay.

Put the Port wire from the LEDwiz to in1

Run appropriate Power to the ground and VCC next to the input

Run the + to the Shaker, Solenoid or Fan

on other side of the board hook the ground from the power supply to GND

Then pick one of the outs and that will go to the shaker motor or solenoid

You may want to add a fuse in the circuit

You may or may not need this

I put one of these in between the shaker motor and the output board because sometimes the shaker motor would just go crazy

To hook this up take the OUT wire and hook it to the power negative, take the 12+ wire from the power supply hook it to the power +

Then the motor plus and motor negative hook to the shaker motor

Thanks much to both of you---you both helped a ton.  

 

One quick follow for those who can provide an opinion. Since I have another ATX power supply that can give me 5V---  can I just run this via 5V and not the 12V and have to step down/dial back the total voltage.  I know the LEDWiz can only handle the 5V (hence the relay board) but wondering if I can run the shaker with 5v and skip the relay and Sainsmart.  I really don't need to shake the holy hell out of the cabinet.  I really just want a gentle vibration.   

 

 

 

These forums and you experts provide so much to the newbies here like me---one day I hope to provide more and ask less.   I have learned a lot in the past 9 months of my build and this is the last toy I am adding.  Well maybe not the last----this feels like it is never done.   :)

The LEDWiz board can handle a lot more than 5V.  It runs on 5V, which can come from the USB connection or external, and from memory can switch directly 48v (someone please correct me) and 1 amp combined per bank of 8 outputs.  There are 4 banks of 8 outputs to which you can connect a +ve voltage per bank.  This +ve connection really just provides the equivalent of a flyback diode as the LedWiz switches -ve.

 

If your shaker runs the way you want it on 5V and starts every time (test this with a switch or similar), then yes you could run it on 5V.  From my experience though, a 12V motor on 5V is a long way from what its designed to do, but if it works the way you want - go for it.

 

The correct way to adjust the intensity of the shaker motor is via PWM and a solid state booster circuit rather than a mechanical booster like a relay.  So with a relay you will always have compromises.

I use a ATX power supply

I use  the 12v with my LEDwiz For my RGB Lights and power for the shaker

I use  the 5v for the addressable LED strips with the Teensy board

  Top Notch!  Thanks again for the input and discussion.   Anyone want a Sainsmart board?   :)

i just hooked my contactor up with this method on a pinscape (kl25 board) and as soon as i connect the output 1 wire to the pinscape board it triggers the contactor instantly, in the software the on/off trigger doesn't seem to work at all, i'm using 12V +/- from the pc psu and from the diagram on the opposed side the single ground is coming from the other 24v PSU that controls the contactor, + from that PSU hooked straight upto the contactor's + and ground to the mosfet board same one as your diagram and as i just menioned. little bit confused why its not working and instantly triggering as soon as i connect to the controller board.

Hello Viper i was having The same problem, it took me 3 months to solver. You need to put a 1k resistor on The dupont wire that goes from The kl25z output to The relay board. And do not put The 5v and The grn wire where you put The inputs on The relay board. You also need to configurate your output as active-low on The pinscape config software.
