#13 Wiring Stepper Drivers To Controller & Panel Mounts #13 / CNC Control Box

CORRECTION 0:47 Input coming into the controller such as the start, hold and reset buttons, the probe and limits switches all need an active low signal - which means when the pin is receiving a voltage (normally 5v) it is disabled, and if that goes to 0V is it active. The coolant and spindle enable pins use an active high so the off state is normally at 0v and that goes up to 12v to turn those on. In the case of stepper drivers a high and low signal result in moving the stepper in one direction or the other. When I built my first controller I didn't use a probe or start/hold buttons, and my limits were simple mechanical limits which didn't require me to investigate how they worked.

In this video I wire the M542T stepper drivers to their aviation panel mounts and the controller. I didn’t do a great job soldering these to the chassis mounts but eventually figures out what I was doing wrong and corrected my first attempt in a separate video. Once that is uploaded later this week I will link to that that video here:

I used the DC power out feature as a PWM to check my VFD and that was great. But it is a little pricey and you don't to send that much to simply solder - you could use an iron like this instead: https://goo.gl/xkedGL - make sure you get one which corresponds to the electrical supply of your area.
