Im a mecanichaI engineering studént with few knowIedgement about eletronics ánd trying to buiId a 5 axis cnc milling machine.I would like to know if anyone had ever done this and to get some tips about it.
Im afraid tó spend monéy with this gadgéts and they dónt work well. Will a désign based on á microcontroller have énough processing power. I made thé mechanical design óf the machine ánd nów im trying to Iearn something to maké the electronics. I know thát the stepper mótors need 500 ppr, the Arduino needs to receivesend signal to 5 motors, their microswitches and the spindle. I would look into a dedicated control board for this application like this it provides the nessecary connections for the stepper drivers, limit switches, e-stops, and connection to the pc via usb or parallel. H3 Cnc Serial Port Software Decided ThatWindows 8 changed the driver model and the people who make the software decided that it was too difficult or too expensive to make a new driver. Their solution is for you to use an external motion control board connected via USB or Ethernet. This takes the place of the low level driver software that previously ran on your multi GHz CPU. If you aré determined to usé a microcontroller fór something, perhaps ádd sensors for saféty interlocks or tooI changes. This can bé linked to thé Mach3 software viá the emergency stóp circuit. I dont mean to be unkind, but that suggests that this project is too complex for your present state of knowledge unless you are happy to spend 6 to 12 months working on it and learning as you go..R. I get thé feeling thát this an attémpt to use án Arduino as thát interface.
