    Hi, folks. I have hot pots! After maybe towards an hour, my stepper motors overheat. They can get to 80+ degrees C! (useful to light my cigarettes from..;)
    I'm using that blasted TB6560 blue Chinese board (with NEMA 17's on a Zen 6x6 router), and was wondering if setting the DIP switches to a lower amperage might help? I'm running it at 15v, and it sucks (the board) 1.5A max on a typical cut.
    On startup, all motors run fine, with no untoward noises.

    I worried about the steppers on my machine which probably reach that kind of temp. When I googled it a bit, the general view was that steppers do run hot, and I seem to remember figures of over 100C being normal. I don't worry if it's too hot to touch as long as it isn't hot enough to boil water (i.e. fizz when you touch it with a wet fingertip). I did turn down the max current a bit, which helped.

    I have found a PRC i/r thermometer very useful for this, too - it probably only cost me a fiver from fleabay... Cheers for your response.

    It takes most people by surprise but
    it is normal for stepper motors run too hot to the touch

    different manufacturers give the maximum temperature as 70 to 80 C
