It has been a while since I last posted... Since this time I have been very busy working on my machine. I have tided up all of the wiring, and sorted out a power source. Also I have replaced the normal M3 bolts on the bottom of the bed for nylon lockable nuts. This means that the bolts will not loosen easily. As previously I found that when transporting my machine the nuts can easily loosen themselves off the bottom of the bed. I have also added X4 stepper motor drivers to the machine.
