    Hello,

    it's a long time ago I build my simulator with this Interface.
    Its now time to give him a second life, as for me it is collecting dust. I will gift this to a friend.

    In the past I build a controller Box with 2 Monster Moto shields, one per motor. As i had little knowledge, and acces to tools, my controller box is quite ugly. I know managed to short one Monster moto while trying to remember which cable goes where ^^

    I was lucky and found a spare Moto Monster shield which i had ordered years ago. I am using the popular 90 ZYT Motors with MCP4 gearbox.

    Before it was a platform Simulator, which is now converted to a seatmover. Did any of you have any experience if one Monster Motoshield will be enough for both motors, or should I stick with one shield per Motor.

    If I understand it correctly, each channel of the Shield can supply 30A to the Motor peak. The motor is ratet at 23 Amps per label, so in theory one shield should be enough.

    I also have the pololu equivalent laying around, which maybe a better option than the cloned aliexpress monster moto.

    Clone MMs have long fallen out of favor with members.

    Member experience has led to the advice that even brand new clone MMs requires testing: https://xsimulator.net/community/faq/monster-moto-testing-before-use.158/

    I would suggest 1 MM per motor if they pass testing. The JRKs may be a better option. There are also other possibilities, for example: https://xsimulator.net/community/faq/reasonably-priced-100a-motor-controllers.412/

    Hello,

    I am aware of the issues with faulty clones, and tested this one years ago so it should be fine. Since the actual failure occured because of my wireing fail, I will replace the one defectrive driver. They worked flawless in the past when the sim was in use.

    If they will fail I will upgrade to another driver. Thanks for pointing me to the 100A driver. This should be a proper replacement for the future.

    While searching a little bit, i found this drivers: [​IMG]

    From the specs it looks got for me to drive both of my motors. Has anyone any experience with these drivers? They are a little bit easyer to source than the 100 A ones. It says 60A per channel.

    This is an amazing idea for a father and son project. I wonder, if there is a chance to get the source code of SMC3 and SMC3Utils. Does anybody know, where to get it from?

    you can get it on the first post of this thread :) at least the smc3 source code for the arduino. The Utils is only avalible as an executable as far as i know

    If I recollect correctly @RufusDufus confirmed the loss of the SMC3 utility source code many many years ago, as the result of a corrupted drive.

    Only the Arduino SMC3 Ino files remain, but those are the important bit and have been modified by many others over the years for different hardware.

    That is really a pity
    Ad we haven’t checked the Arduino code yet, we will dig into it.
    I am just wondering, if all the information provided by SimTools will arrive at the Arduino as well - like shown in the attached image.

    SMC3 is for configuring and tuning the hardware range/response, a SimTools plugin is totally separate from that, in that it allows available game telemetry and tuning of that within the hardware parameters/capabilities, be those set by SMC3 or others.

    Spend some time perusing the FAQs to get a bit of an overview: https://www.xsimulator.net/community/faq/
