    Thanks. I wondered if it had any magnetic shielding.
  2. What happens when stepper motor is close to a magnet?

    I'm curious what would happen if a stepper motor is close to a small electromagnet such as those used to lock a door?

    Thanks. That worked. I've tried the machine using pens, and went through 2 of them. Apparently some of the sample gcodes called for deep plunges, which destroyed the pens. I guess I have to learn...

    I'm trying to learn Rhino. I bought the madcam 5 axis for less than $200 using a student discount. Supposed to be very good, though I've yet to use it.

    Most 4 conductor wire would work. I think that 18 gauge is a bit big when trying to solder to the db9 terminals. 20g might work better.

    Hi Arbo. I'm curious since I use the g540 and the ez540 connectors. My steppers get really warm. How warm does yours get...can you grab the motor for a minute or so warm or is it untouchably warm?
