Re: Design & Build of Lanky - A Ozzie 8x4' long gantry router
Pete, if you want to turn up the heat on voltage, Look for motor controllers that accept AC voltage and have a chat to Tortech about Toroid power supplies. The two attached are running 60v AC toroids so I guess the motors get around 90 volts. These were made to my specs by Tortech.
The black box is using Lam Technology stepper drivers and I configure them so they drop the amps to the motor to 30% when the motors are at constant velocity.
The other incomplete Box is using Rtelligent Ethercat drives and closed loop motors.
I did not eperience any issues with higher voltages but had a huge boost in performance.
The next box I build will use 220V AC servos, most likely ethercat ones. That way, there will be no power supply required. Give that serious consideration too.
