    Hi,

    I plan to use the IMS-1 drivers for my 2DOF and I am wondering if someone already used these, otherwise I need to do the programming on my own. Just curious if I can save some time ;-)

    Here is my test setup with one driver and a small motor. I placed everything on an aluminium sheet that fits perfectly in the 5 1/4 inch slot of the computer to be used. That way I don´t need to build an additional case.

    I can't find any projects using the IMS-1 drivers, looks like you are the pioneer!

    @earobbie: The mode2 as described in the link looks like a possible chance. That Bridge is made by the same manufactor afaik.
    Thanks for the link. Otherwise I´ll have to spend some time on the code. I am not too familar with c but it looks close to the stuff I made in python so I guess I´ll get into it with some reading.
    However first I need to make some progress on the hardware... just too few time :(

    So finally I got the 2DOF working and the IMS-1 do pretty well with 24V (Though I believe the psu only deliver 20V, my Voltmeter is a bit tolerant with its display ;-))
    They get a bit warm but since I put them on an aluminium sheet it is not close to a critical temperature.

    It doesn´t look that good for the motors I installed. These are 24V/2A (so 48W) wheelchairmotors and one of them gets really hot.
    So I´ll probably have to replace them with more powerful ones and THAT -might- get the IMS-1 in trouble.
