do-it yourself CNC-machine
Most of the parts are made by ourself. Linear guidance
are made of grinded shafts with bronze bushes.
The machine has moverment dimensions of x-axis 300mm,
in y-axis 200mm and z-axis 70mm.
For controlling the machine AKKON
a self made CNC-software is in use.
mechanics of x-axis
Controlling of x-axis is done by tooth belt.
Mechanics of z-axis
Z-axis is linked directly with the spindel over a jaw
back-side of the CNC-Controller
The USB CNC-Controller
Hardware and software for controlling the machine is
also self-made. With the hardware four stepper motors
can be controlled. There is also an puls with modulated
digital output available. Furtheron digital outputs
for cooling system and vacuum cleaner as well as six
inputs for limit switches. Firmware updates can easily
be uploaded to the controller over USB loaderk..
