Electronics Kit 4.3 Instructions



Electronics Kits 2 to 4

Important Info:
The following info will help you avoid some of the most common mistakes when assembling you electronics kit and machine

Hot Motors?
During your assembly you will want to turn your electronics kit while it is not being controlled by Mach3 (or other controller software) and is not connected to a PC. This is OK to test to see if everything is wired correctly and all the LED's come on. However you should not leave your CNC electronics in this state for any longer than you have to. The DIV268 drives are auto-enable and without a signal from Mach3 they will switch on and send 100% current to the motors in the "Hold" position. Within a couple of minutes your Motors and Drivers will begin to heat up so this should be avoided where possible as there is a chance you can damage both your drivers and motors if left in this state for prolonged periods of time.

Your motors and drivers will not heat up when controlled "correctly" by Mach3.

Following the recommended start up procedure will avoid the issue completely.

Attaching an electric drill or crank handle to the back of your stepper motors?
While assembling your machine you may find winding your axis's back and forth by hand slow and tiresome and be tempted to attach an electric drill to the shaft at the back of the stepper motor. This can be fairly disastrous as a motor becomes a generator when driven by an external force. The power feed back to the drivers will most likely exceeded their capacity in both voltage and amperage and permanently damage them.

Please don't externally/physically drive your motors.

Using a knob/wheel on the back of a stepper motor is fine when being turned by hand. Remember to turn your electronics off first (do not force motors in the hold position, it will damage them).
