Kits 2 to 4
following info will help you avoid some of the most common
mistakes when assembling you electronics kit and machine
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.
and drivers will not heat up when controlled
"correctly" by Mach3.
Following the recommended start
up procedure will avoid the issue completely.
electric drill or crank handle to the back of your stepper motors?
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
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
