    Thanks for the info

    when my H-bridge gets here I will hook it up

    Yeah they are around $1.50-$3.00 each work great. Keep in mind you hook this to the ledwiz input. Not the normal outputs of the ledwiz.

    I’ve seen this posted before… why is it only the shaker that needs to be hooked to the chip like this???

    I “think” it’s because you want to bypass that buffer chip in order to get the full voltage range of the PWM signal.

    If you don’t do that, then I think it will still work, but you won’t get as high an output for up to max, and as low as you want for low. So your shaker won’t be working to its full range or potential.

    I have the H-bridge hooked up and working but the maximum voltage going to the shaker motor is 7.8 V

    Are you connected (soldered) like in the diagram above?

    Confirm what your max intensity is set to in DOF Config Tool.

    If its not 48…then maybe its normal possibly to have less voltage?Try maxing it out (if not already) to see if it changes.

    I’m not sure if that setting only controls the width of the pulses, or if it affects your voltage output.

    Terry replied before I could but he is correct as always…what’s your max and min in tool? How are you testing the shaker? Try the dof test table and see what you get

    I have it hooked up exactly like both diagrams…

    I use the test Menu in DOFLinx

    I also used the new tester from DOF R3++

    DOFLinx is a good tester to use. I never checked my voltage while it was active…so I can’t compare… but my MAX output was simply way too much, even though my heavy as crap cabinet doesn’t budge. :)

    Is it running good at all at 7+ volts though?

    If input voltage is 12v maybe you have a bad h bridge output? You could try the other output on same h bridge and see if it’s same? Are your jumpers setup the same as pictured on the h bridge?

    When I was hook to the solid state relay it was way too fast so it must have been getting 12 V then..

    Is it running good at all at 7+ volts though? — half speed

    You could try the other output on same h bridge and see if it’s same? — I will check

    Are your jumpers setup the same as pictured on the h bridge? — Yes

    This is the one I have

    https://www.amazon.com/gp/product/B06XR1YNH4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

    At 12 V the motor pulls 3.2 continuous amp…

    The rating on the H-bridge is 2.0 amp ….

    So would appear the H-bridge I have is not going to work for this…

    Do you have a link to the exact H-bridge you are using?

    Looks like you have the exact same one I have. Mine has been running for 4-5 years with zero issues as have many others setup the same way.  Strange!

    You have the wire attached to input of the ledwiz and not output right?

    So your say running at 12 v it’s drawing to much? Or is it drawing to much at  7v? Did you get it to run at full speed 12v yet?

    you have 2 ledwiz’s? or just one but its device ID 2?

    When I don’t use the H-bridge the motor gets 12 V and pulling 3.2 amps –> Very fast

    When I use the H-bridge it’s only getting about 8 V and pulling about 2.0 amps

    This H-bridge is a maximum of 2 amps…  So I wonder if it’s regulating…. It will not let me use more than 2 amps

    Maybe TerryRed will charm in and give me a link to where he bought his…

    You have 2 ledwiz’s?   –  Yes

    It’s the same model h bridge that I use perhaps the cap on motor is causing the issue?  Mine don’t have a cap and I’m sure it’s getting full voltage

    Where I got my shaker. I did NOT use the PCB that came with it….well I did at first…. thinking the diode was in parallel, but it was actually in series!

    https://www.pinballlife.com/index.php?p=product&id=1352

    As a result, poor randr had me pestering him at night…

    It wound up blowing one of my h-bridge’s outputs. I used the other output after I saw the error of my ways, and it works perfect!

    It would appear I bought the same shaker motor set up that you did….

    On your motor did you leave the capacitor on their?

    TerryRed – Do you happen to have a link to To the H-bridge That you bought?

    Because the H-bridge I bought is not cooperating

    Yes, I left that cap on there. I didn’t change anything with the motor.

     

    What I ordered…

    Thanks – on order – We will see if they work for me
